IC200MDL243 
Input Module, 120 V AC Isolated 16 Points 
Discrete input module IC200MDL243 provides 16 isolated input points. Inputs 
are positive logic or sourcing-type inputs; they receive current from AC input 
devices and return the current on the common.  Each input has its own return.  
 
Power for module operation comes from the backplane.  
Intelligent processing for the module is performed by the CPU or NIU.  The 
module provides 16 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.
