10.7

IC200UEX214
28 Point Micro PLC Expansion Unit, (16) 24Vdc
In, (12) 24Vdc Out, 24Vdc Power Supply

VersaMax Micro PLC Expansion Unit IC200UEX214 accepts sixteen DC inputs and provides
four low-current and eight high-current DC transistor outputs. It uses +24Vdc nominal input
power.

10.7.1

DC Power

The 24Vdc power source must have enough transient current capability to support the
inrush current of the power supply and to maintain a 24Vdc voltage level.

10.7.2

DC Inputs

Sixteen configurable DC inputs can be used as positive or negative logic inputs. The inputs
are compatible with a wide range of input devices, such as pushbuttons, limit switches, and
electronic proximity switches.

The 24Vdc 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.

10.7.3

Transistor Outputs

Twelve positive-logic transistor output circuits can be used to switch devices like valves,
lamps or contactors. External fusing should be provided to protect the outputs. Otherwise,
a load short could damage the module output transistor, which is not user replaceable. Fast
fuses are recommended.

Outputs are grouped in two groups with separated incoming supply. Each group contains 4
outputs with a maximum load of 0.5A and 2 outputs with a maximum load of 1A.

All outputs are isolated between field and logic and are switching positive voltage. The
outputs have one common incoming supply (VC) and one common ground (COM). 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.
