Supply
VersaMax Micro PLC Expansion Unit IC200UEC008 accepts four 24Vdc inputs and provides
four 24Vdc source-type transistor outputs with Electronic Short Circuit Protection. The
module requires +24Vdc nominal input power.
9.2.1
DC Inputs
The four 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 +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.
9.2.2
Transistor Outputs
Expansion Unit IC200UEC008 has four source-type high-current transistor outputs. All
outputs are isolated between field and logic and are switching positive voltage.
All 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.
