IC200MDL244 
Input Module, 240 V AC Isolated 8 Points 
 
Discrete Input Module IC200MDL244 provides 8 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 8 bits of discrete input data (4 bits per card). 
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.
