IC200MDL144
Input Module, 240 V AC Isolated 4 Points
Discrete Input Module IC200MDL144 provides 4 isolated discrete inputs. Inputs
are positive logic or sourcing-type inputs; they receive current from AC input
devices and return the current on the common. Input devices are connected
between the input terminals and common terminals.

Power for module operation comes from the backplane.
Intelligent processing for the module is performed by the CPU or NIU. The
module provides 4 bits of discrete input data.
LED Indicators
Individual green LEDs indicate the on/off state of each input point.
The green OK LED is ON when backplane power is present to the module.
