IC200MDL650
Input Module, 24 V DC Pos/Neg Logic 32 Points
Discrete input module IC200MDL650 provides four groups of 8 discrete inputs.
Inputs in each group can be either positive logic inputs that receive current from
input devices and return the current on the common, or negative-logic inputs
that receive current from the common and return current to the input device.
Input devices are connected between the input terminals and common
terminals.

INPUT 24VDC
POS/NEG GRP 32PT
Note: Negative-logic functionality requires module version IC200MDL650C or
higher.
Power for module operation comes from the backplane.
Intelligent processing for this module is performed by the CPU or NIU. The
module provides 32 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.
Configuration Parameters
The module’s basic input on/off response time is 0.5ms.
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 CPU 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).
