Discrete input/output module IC200MDD840 provides 20 discrete inputs and 12
relay outputs. The inputs form two groups of 10 points. Inputs are positive logic or
sourcing-type inputs; they receive current from devices and return the current on
the common. The relay outputs form two groups of 6 points. Each output group
can drive a maximum of 8 A.
Power for module operation comes from the backplane. Output loads must be
powered by an external source.
Intelligent processing for the module is performed by the CPU or NIU. The module
provides 20 bits of discrete input data and receives 12 bits of discrete output data.
LED Indicators
Individual green LEDs indicate the on/off state of the output points and input
points.
The output LEDs are logic-driven and independent of the load conditions.
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 through 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).
