IC200MDL631
Input Module, 125VDC Pos/Neg Logic Isolated 8 Points
Discrete input module IC200MDL631 provides 8 discrete isolated inputs. Inputs can
be either positive logic inputs that receive current from input devices and return the
current on the return, or negative-logic inputs that receive current from the return and
return current to the input device. Input devices are connected between the input
terminals and return terminals.

Power for module operation comes from the backplane.
Intelligent processing for this module is performed by the CPU or NIU. The module
provides 8 bits of discrete input data.
LED Indicators
Individual green LEDs indicate the on/off state of each input point. Backplane
power must be present for LEDs to provide status of inputs.
The green OK LED is on when backplane power is present to the module.
Configuration Parameters
The module’s basic input on/off response time is 0.5 ms.
For some applications, it may be preferable to add additional filtering to compensate
for conditions such as noise spikes or switch bounce. Input filter times of 0ms,
1.0ms, or 7.0ms are selectable via software configuration, for total response times of
0.5ms, 1.5ms, and 7.5ms respectively. The default is 1.0ms filter time (total response
time is 1.5ms).
