In many cases, using the built-in auxiliary +24VDC supply can result in a cost

savings for your control system. It can power combined loads up to 500 mA, which is

enough to eliminate the need for an additional power supply in some applications. If

you are the system designer for your application, you may be able to select and

design in field devices which can use the +24VDC auxiliary supply.

DC-powered DL105 Micro PLCs are designed for application environments in which

low-voltage DC power is more readily available than AC. These include a wide range

of battery-powered applications, such as remotely-located control, in vehicles,

portable machines, etc. For this application type, all input devices and output loads

typically use the same DC power source. The F1-130DR-D and F1-130DD-D are

compatible with either +12VDC or +24VDC systems. Typical wiring for DC-powered

applications is shown in the following diagram.

If the loads cannot be powered from the Micro PLC supply, then a separate supply

Some applications will use the Micro PLC power source to also power the input

circuit. This typically occurs on a DC-powered DL105, as shown in the drawing

below to the left. The inputs share the PLC power source supply, while the outputs

have their own separate supply.

A worst-case scenario, from a cost and complexity view-point, is an application

which requires separate power sources for the PLC, input devices, and output loads.

The example wiring diagram below on the right shows how this can work, but also

that the auxiliary supply out is an unused resource. For these reasons, you’ll

probably want to avoid this situation if possible.

Sinking / Sourcing

Before going further in our study of wiring strategies, we must have a solid

Concepts

understanding of “sinking” and “sourcing” concepts. Use of these terms occurs

frequently in input or output circuit discussions. It is the goal of this section to make

these concepts easy to understand, further ensuring your success in installation.

First we give the following short definitions, followed by practical applications.

Sinking = Path to supply ground (-)

Sourcing = Path to supply source (+)

First you will notice that these are only associated with DC circuits and not AC,

because of the reference to (+) and (-) polarities. Therefore, sinking and sourcing

terminology only applies to DC input and output circuits. Input and output points that

are either sinking or sourcing can conduct current in only one direction. This means it

is possible to connect the external supply and field device to the I/O point with current

trying to flow in the wrong direction, and the circuit will not operate. However, we can

successfully connect the supply and field device every time by understanding

“sourcing” and “sinking”.

For example, the figure to the right depicts

PLC

a “sinking” input. To properly connect the

Input

external supply, we just have to connect it

(sinking)

so the the input provides a path to ground

(-). So, we start at the PLC input terminal,

exit at the common terminal, and connect

Common

the supply (-) to the common terminal. By

adding the switch, between the supply (+)

and the input, we have completed the

circuit. Current flows in the direction of the

arrow when the switch is closed.

By applying the circuit principle above to the four possible combinations of

input/output sinking/sourcing types, we have the four circuits as shown below.

DL105 Micro PLCs provide all except the sourcing output I/O circuit types.

terminals instead of eight.

Note: In the circuit above, the current in the common path is 4 times any channel’s

input current when all inputs are energized. This is especially important in output

circuits, where heavier gauge wire is sometimes necessary on commons.

Most DL105 input and output circuits are

grouped into banks that share a common

common grouping is on the wiring label.

The I/O common grouping bar, labeled at

The following complete label shows two banks of four inputs and one bank of two.

The following label for relay outputs shows four banks of two output points each.

The last label below for DC outputs has no common grouping bar. In this unique

case, all eight outputs share the same electrical common. The common is available

on three terminals, so there is a physical place to connect each point’s common wire.

Connecting DC I/O

In the previous section on Sourcing and Sinking concepts, we explained that DC I/O

circuits sometimes will only allow current to flow one way. This is also true for many of

Field Devices

the field devices which have solid-state (transistor) interfaces. In other words, field

devices can also be sourcing or sinking. When connecting two devices in a series

DC circuit, one must be wired as sourcing and the other as sinking.

Solid State

The DL105’s DC inputs are flexible in that they detect current flow in either direction,

Input Sensors

so they can be wired as either sourcing or sinking. In the following circuit, a field

device has an open-collector NPN transistor output. It sinks current from the PLC

input point, which sources current. The power supply can be the +24 auxiliary supply

or another supply (+12 VDC or +24VDC), as long as the input specifications are met.

not to send DC power to an actuator.

The DL105’s DC outputs are sinking-only. This means that each DC output provides

a path to ground when it is energized. Also, remember that all eight outputs have the

same electrical common, even though there are three common terminal screws.

Finally, recall that the DC output circuit requires power (10 - 30 VDC) from an

external power source.

In the following circuit, the PLC output point sinks current to the output common

when energized. It is connected to a sourcing input of a field device input.

In the next example we connect a PLC DC output point to the sinking input of a field

device. This is a bit tricky, because both the PLC output and field device input are

sinking type. Since the circuit must have one sourcing and one sinking device, we

add sourcing capability to the PLC output by using a pull-up resistor. In the circuit

below, we connect Rpull-up from the output to the DC output circuit power input.

NOTE: DO NOT attempt to drive a heavy load (>25 mA) with this pull-up method.

NOTE 2: Using the pull-up resistor to implement a sourcing output has the effect of

inverting the output point logic. In other words, the field device input is energized

when the PLC output is OFF, from a ladder logic point-of-view. Your ladder program

must comprehend this and generate an inverted output. Or, you may choose to

cancel the effect of the inversion elsewhere, such as in the field device.

It is important to choose the correct value of R pull-up. In order to do so, we need to

know the nominal input current to the field device (I input) when the input is energized.

If this value is not known, it can be calculated as shown (a typical value is 15 mA).

Then use I input and the voltage of the external supply to compute R pull-up. Then

calculate the power Ppull-up (in watts), in order to size R pull-up properly.

ways to wire relay outputs to the loads. Note that there are eight normally-open

SPST relays available. They are organized into four pairs with individual commons.

Surge Suppresion

Inductive load devices (devices with a coil) generate transient voltages when

For Inductive

de-energized with a relay contact. When a relay contact is closed it “bounces”, which

Loads

energizes and de-energizes the coil until the “bouncing” stops. The transient

voltages generated are much larger in amplitude than the supply voltage, especially

with a DC supply voltage.

When switching a DC-supplied inductive load the full supply voltage is always

present when the relay contact opens

(or

“bounces”). When switching an

AC-supplied inductive load there is one chance in 60 (60 Hz) or 50 (50 Hz) that the

relay contact will open (or “bounce”) when the AC sine wave is zero crossing. If the

voltage is not zero when the relay contact opens there is energy stored in the

inductor that is released when the voltage to the inductor is suddenly removed. This

release of energy is the cause of the transient voltages.

When inductive load devices (motors, motor starters, interposing relays, solenoids,

valves, etc.) are controlled with relay contacts, it is recommended that a surge

suppression device be connected directly across the coil of the field device. If the

inductive device has plug-type connectors, the suppression device can be installed

on the terminal block of the relay output.

Transient Voltage Suppressors (TVS or transorb) provide the best surge and

transient suppression of AC and DC powered coils, providing the fastest response

with the smallest overshoot.

Metal Oxide Varistors

(MOV) provide the next best surge and transient

suppression of AC and DC powered coils.

opening a contact switching a 24 VDC solenoid. Notice the large voltage spike.

Prolonging Relay

Relay contacts wear according to the amount of relay switching, amount of spark

created at the time of open or closure, and presence of airborne contaminants.

There are some steps you can take to help prolong the life of relay contacts, such as

switching the relay on or off only when it is necessary, and if possible, switching the

load on or off at a time when it will draw the least current. Also, take measures to

suppress inductive voltage spikes from inductive DC loads such as contactors and

solenoids.

For inductive loads in DC circuits we recommend using a suppression diode as

shown in the following diagram (DO NOT use this circuit with an AC power supply).

When the load is energized the diode is reverse-biased (high impedance). When the

load is turned off, energy stored in its coil is released in the form of a negative-going

voltage spike. At this moment the diode is forward-biased (low impedance) and

shunts the energy to ground. This protects the relay contacts from the high voltage

arc that would occur just as the contacts are opening.

Place the diode as close to the inductive field device as possible. Use a diode with a

peak inverse voltage rating (PIV) at least 100 PIV, 3A forward current or larger. Use a

fast-recovery type (such as Schottky type). DO NOT use a small-signal diode such

as 1N914, 1N941, etc. Be sure the diode is in the circuit correctly before operation. If

installed backwards, it short-circuits the supply when the relay energizes.

The ten AC input channels use terminals on the bottom connector. This input type

also works for high-voltage DC signals. Inputs are organized into two banks of four,

plus one bank of two. Each bank has an isolated common terminal. In the case of DC

input signals, the input may be wired in as either the sourcing or sinking type. The

wiring example above shows all commons connected together, but separate

supplies and common circuits may be used. The equivalent input circuit shows one

channel of a typical bank.

The eight current sinking DC output channels use terminals on the top connector.

The three common terminals are internally connected, meaning all outputs actually

share the same electrical common. The wiring example above shows all commons

connected together, because it is best to share the common current among the three

terminal connections. Note the requirement for external power on the end

(right-most) terminal. The equivalent output circuit shows one channel of the bank of

circuits. Since the outputs are the sinking type, you’ll need to connect +24V to the

output commons. Be sure the combined load currents do not exceed 0.5 A. Note that

on the F1-130AD, the +24V auxiliary output is not high enough to power its input

circuits (input ON threshold is 90VDC).

internally connected, meaning all outputs actually share the same electrical

because it is best to share the common current among the three terminal

connections. The equivalent output circuit shows one channel of the bank of eight.

No Auxiliary +24V

The F1-130DR-D does not include a +24V output, as do most other DL105 PLCs.

Power Supply

Since this unit requires +24V as the main supply input, it it usually most economical

to use the same supply to power suitable field devices. In the wiring diagram above,

High-speed Input and Pulse Output Features

Introduction

Built-in Motion

Many machine control applications

Control Solution

require various types of simple

high-speed monitoring and control. These

applications usually involve some type of

motion control, or high-speed interrupts

for time-critical events. The DL105 Micro

PLC solves this traditionally expensive

problem with built-in CPU enhancements.

ÎÎ

The available high-speed input features are:

S High Speed Counter (5 kHz max.) with up to 24 counter presets and

built-in interrupt subroutine, counts up only, with reset

S Quadrature encoder inputs to measure counts and clockwise or counter

clockwise direction (5 kHz max.), counts up or down, with reset

S High-speed interrupt input for immediate response to critical or

time-sensitive tasks

S Pulse catch feature to monitor one input point, having a pulse width as

small as 100mS (0.1ms)

S Programmable discrete filtering (both on and off delay up to 99ms) to

ensure input signal integrity (this is the default mode for inputs X0-X3)

The available pulse output features are:

S Single-axis programmable pulse output (7 kHz max.) with three profile

types, including trapezoidal moves, registration, and velocity control

10 Discrete Inputs

The high-speed I/O circuit (HSIO) is dedicated to the first four inputs (X0 - X3) and

the first two outputs (Y0 - Y1). We might think of this as a “CPU helper”. In the default

operation (called “Mode 60”) the HSIO circuit just passes through the I/O signals to

or from the CPU, so that all ten inputs behave equally and all eight outputs behave

equally. When the CPU is configured in any other HSIO Mode, the HSIO circuit

imposes a specialized function on the portion of inputs and outputs shown. The

HSIO circuit operates independently of the CPU program scan. This provides

accurate measurement and capturing of high-speed I/O activity while the CPU is

busy with ladder program execution.

Wiring Diagrams

After choosing the appropriate HSIO mode for your application, you’ll need to refer to

for Each HSIO

the section in this chapter for that specific mode. Each section includes wiring

High-speed Input and Pulse Output Features

Mode 10: High-Speed Counter

Purpose

The HSIO circuit contains one high-speed counter. A single pulse train from an

external source (X0) clocks the counter on each signal leading edge. The counter

counts only upwards, from 0 to 99999999. The counter compares the current count

with up to 24 preset values, which you define. The purpose of the presets is to quickly

cause an action upon arrival at specific counts, making it ideal for such applications

as cut-to-length. It uses counter registers CT76 and CT77 in the CPU.

Functional Block Refer to the block diagram below. When the lower byte of HSIO Mode register V7633

Diagram

contains a BCD “10”, the high-speed up counter in the HSIO circuit is enabled. X0

automatically becomes the “clock” input for the high-speed counter, incrementing it

upon each off-to-on transition. The external reset input on X2 is the default

configuration for Mode 10. Inputs X1 and X3 are filtered inputs, available to the

ladder program.

High-Speed Input and Pulse Output Features

A general wiring diagram for counters/encoders to the DL105 in HSIO Mode 10 is

Wiring Diagram

shown below. Many types of pulse-generating devices may be used, such as

proximity switches, single-channel encoders, magnetic or optical sensors, etc.

Devices with sinking outputs (NPN open collector) are probably the best choice for

interfacing. If the counter sources to the inputs, it must output 12 to 24 VDC. Note

that devices with 5V sourcing outputs will not work with DL105 inputs.

Interfacing to

The DL105’s DC inputs are flexible in that they detect current flow in either direction,

so they can be wired to a counter with either sourcing or sinking outputs. In the

following circuit, a counter has open-collector NPN transistor outputs. It sinks

current from the PLC input point, which sources current. The power supply can be

Presets and

The goal of counting is to do a special action when the count reaches a preset value.

Special Relays

Refer to the figure below. The counter features 24 presets, which you can program.

A preset is a number you derive and store so that the counter will constantly compare

the current count with the preset. When the two are equal, a special relay contact is

energized and program execution jumps to the interrupt routine. We recommend

using the special relay(s) in the interrupt service routine to cause any immediate

action you desire. After the interrupt service routine is complete, the CPU returns to

the ladder program, resuming program execution from the point of interruption. The

compare function is ready for the next preset event.
