IC200UEX122
14-Point Expansion Unit with 24DC Power, (8)
24DC Inputs, (2) High-Current and (4) Low-
Current Transistor Outputs with ESCP

VersaMax Micro PLC Expansion Unit IC200UEX122 accepts eight DC inputs and provides two
low-current and four high-current DC transistor outputs. The outputs have electronic short
circuit protection. The module requires +24Vdc nominal input power.

9.16.1

DC Inputs

The 24 volt DC input circuits can have positive or negative logic characteristics. Inputs are
compatible with a wide range of devices, such as pushbuttons, limit switches, and electronic
proximity switches.

The built-in isolated +24Vdc supply can be used for input devices and to power the DC input
circuits. The combination of input circuit current and external device current must not
exceed 200 mA.

9.16.2

Outputs

Expansion Unit UEX122 has two high-current transistor outputs (Q1 and Q2) and four low-
current transistor outputs (Q3 to Q6). They can be used as positive or negative logic
standard inputs.

All outputs are isolated between field and logic and are switching positive voltage.

All six outputs have electronic short-circuit protection; no fuses are needed to protect the
outputs.

An external source of 12/24Vdc power must be provided to power the outputs. The outputs
share this common incoming 24Vdc supply and one common ground. The outputs are able
to drive high inrush currents (8 times the rated current) and are protected against negative
voltage pulses. This makes it possible to switch lamps and inductive loads.

10.1.1

Removable Terminal Strips

The removable terminal assemblies are protected by hinged covers. After turning off power
to the Expansion Unit, a terminal assembly and attached field wiring can be separated from
the Expansion Unit by removing two screws.

10.1.2

Expansion Connector

The connector on the left side of the Expansion Unit is used to connect to the Micro PLC or
to the outgoing connector on the previous Expansion Unit. The connector on the right side
of the Expansion Unit can be used to attach to the next Expansion Unit.

10.1.3

Status LEDs

LEDs on the Expansion Unit provide quick visual verification of operating status. In addition
to LEDs Expansion Unit local Power and OK mode, there is an LED for each I/O point.

10.1.4

Cables

A 0.1 meter ribbon cable (IC200CBL501) is provided with each Expansion Unit. Cables are
also available in 0.5 meter (IC200CBL505) and 1 meter (IC200CBL510) lengths.

IC200UEX209
28 Point Micro PLC Expansion Unit, (16) 120Vac
In, (2/10) Relay Out, 120/240Vac Power Supply

VersaMax Micro PLC Expansion Unit IC200UEX209 accepts sixteen AC inputs and provides
two relay outputs at 10 Amps and ten relay outputs at 2 Amps. It uses 100Vac to 240Vac
nominal input power.

10.2.1

AC Inputs

The 120Vac input circuits are reactive (resistor/capacitor) inputs. The input circuits require
an AC power source: they cannot be used with a DC power source. Inputs are compatible
with a wide range of input devices, such as pushbuttons, limit switches, and electronic
proximity switches. Power to operate the field devices must be supplied.

10.2.2

Relay Outputs

The relay outputs can control many types of load devices such as motor starters, solenoids,
and indicators. The switching capacity of each of these circuits is 2 amps. An external source
of AC or DC power must be supplied to operate field devices.

AC Inputs

10.3.2

AC Outputs

The 120/240Vac, 0.5 Amp triac outputs are provided in isolated groups. The commons are
not tied together inside the module. This allows each group to be used on different phases
of the AC supply or to be powered from the same supply. Each group is protected with a
replaceable 3.15 amp fuse for its common. Also, an RC snubber is provided for each output
to protect against transient electrical noise on the power line.

AC power to operate loads connected to outputs must be supplied from an external
source.

This module provides a high degree of inrush current (10x the rated current) which makes
the outputs suitable for controlling a wide range of inductive and incandescent loads.
