IC200UDR003
14-Point Micro PLC, (8) 12Vdc In, (6) Relay Out,
12Vdc Power Supply

VersaMax Micro PLC IC200UDR003 accepts eight DC inputs and provides six normally open
2 Amp relay outputs that can control 5 to 30Vdc or 5 to 250Vac output devices. It uses
+12Vdc nominal input power for PLC operation.

3.10.1

DC Power

The DC power supply requires more current at startup voltage (approximately 4Vdc) than
at rated input voltage.  A minimum of 2.0 A is required to start up the DC power supply. If
configured to disable power-up diagnostics, the PLC begins logic solution 100ms after the
voltage level of the power supply input reaches and maintains  24Vdc. The 24Vdc power
source  for  the  PLC  must  have  enough  transient  current  capability  to  support  the  inrush
current  of  the  power  supply  and  to  maintain  a  24Vdc  voltage  level  (see  power  supply
specifications for inrush requirements).

3.10.2

DC Inputs

Eight configurable DC inputs can be used as positive or negative logic standard or High-
Speed Counter inputs. When used as standard inputs, they are compatible with a wide range
of devices, such as pushbuttons, limit switches, and electronic proximity switches.

The Micro PLC 12Vdc supply can be used for input devices and to power the DC input circuits
at about 7.5 mA per input. The combination of input circuit current and external device
current must not exceed 200 mA.

3.10.3

Relay Outputs

The  six  normally-open  Form  A  relay  outputs  (SPST-single  pole  single  throw)  can  control
many  types  of  devices  such  as  motor  starters,  solenoids,  and  indicators.  Power  for  the
internal relay coils is provided by the internal supply.  An external source of AC or DC power
must be supplied to operate field devices.

The relay outputs can be configured as HSC outputs. They cannot be used as Pulse Train or
PWM outputs. Connections and specifications for HSC outputs are the same as for standard
relay outputs.

4.1.1

Run/Stop Switch

The Run/Stop switch can be configured as a run/stop switch or a memory protect switch and
used for clearing faults when a fatal fault exists.

4.1.2

Ports

Port 1 is a built-in RS-232 serial port with an RJ-45 connector.

A second port can be added to a Micro-20 PLC using one of the port Option Modules
described in Chapter 14:. If a second port is installed, both ports can be used for
programming. Only one port can be used at a time for programming, but both ports can be
used for monitoring at the same time.

Port 1 and the optional Port 2 are individually configurable for SNP master/slave, RTU
master/slave, and Serial I/O protocols. Both 4-wire and 2-wire RTU are supported when the
RS-485 Port Option module is installed as port 2. Port 2 does not support hardware flow
control. When either port is being used for RTU slave, it automatically switches to SNP slave
mode when that port is being used by the programmer. If a port is configured for Serial I/O,

RTU Master, or SNP Master operation, that port defaults to SNP slave and automatically
reverts to SNP slave when the CPU is in Stop mode.

Either port can be  software-configured to set up communications between the CPU and
various  serial  devices.  An  external  device  can  obtain  power  from  the  port  if  it  requires
200mA or less at 5Vdc.

4.1.3

Analog Inputs

The RS232 Option Module (IC200USB001) or the RS485 Option Module (IC200USB002) can
provide two 0-10V analog inputs. See Chapter 14: for more information about option
modules. The two inputs can be used to adjust the values in analog registers %AI016 (input
1) and %AI017 (input 2). An example use for the analog inputs would be to set threshold
values for use in logical relationships with other inputs/outputs.

4.1.4

Removable Terminal Strips

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

4.1.5

Status LEDs

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

4.1.6

Backup Battery

The Micro PLC uses a large value capacitor to provide memory retention current to the
System/User RAM and the Time-of-Day clock when the power supply is either not present
or not powered up. The capacitor retains memory contents for at least 30 minutes.

To maintain memory for longer than this, a replaceable battery assembly can be installed in
the battery holder, as described in Chapter 15:. The Micro PLC reports the battery state to
the PLC Fault Table and also uses Status Bits %SA011 and %S0014 to indicate the battery
state.

High-Speed Counters

All VersaMax Micro PLCs with DC power can be configured to provide built-in High-Speed
Counter and pulse operation.

When configured for High-Speed Counter operation, inputs can be set up as:

•

Up to four Type A Counters or

•

One Type A and one Type B Counter.

•

Up to four Type A_32 Counters or

control applications such as meter proving, turbine flow meter, velocity measurement,
material handling, motion control, and process control.

Each counter can be enabled independently. Type A counters can be configured for up or
down counting (default is up) and for positive or negative edge detection (default is
positive). The type B counter provides an A Quad B counting function.

Supply

VersaMax Micro PLC IC200UDD020 accepts twelve DC inputs and provides four ESCP
outputs and four 24Vdc low-current outputs. It uses +24Vdc nominal input power for PLC
operation.

4.4.1

DC Power

If configured to disable power-up diagnostics, the PLC begins logic solution 100ms after the
voltage level of the power supply input reaches and maintains its nominal voltage (24Vdc).
The power source for the PLC must have enough transient current capability to support the
inrush current of the power supply and to maintain the nominal voltage level (see power
supply specifications for inrush requirements).

4.4.2

DC Inputs

The twelve configurable DC inputs can be used as positive or negative logic standard inputs.
Eight of these inputs can be used for High-Speed Counter inputs. When used as standard
inputs, they are compatible with a wide range of input devices, such as pushbuttons, limit
switches, and electronic proximity switches.

The Micro PLC +24Vdc supply can be used for input devices and to power the DC input
circuits at about 8mA per input. The combination of input circuit current and external device
current must not exceed 435 mA.
