IC200MDL742
Output Module, 24VDC Positive Logic 0.5 Amp, w/ESCP 32 Points
Discrete output module IC200MDL742 provides two groups of 16 discrete outputs.
Each point has electronic overcurrent protection and short circuit protection, and
generates a fault if either condition exists. The outputs are positive or sourcing type
outputs. They switch the loads to the positive side of the DC supply and thus supply
current to the loads.

An external DC power supply must be provided to switch power to the loads.
Intelligent processing for this module is performed by the CPU or NIU. The module
receives 32 bits of discrete output data.
LED Indicators
Individual green LEDs indicate the on/off state of the output points. The LEDs are
dependent on field power, but independent of load conditions.
Individual amber LEDs indicate overload conditions on each output point.
The green FLD PWR LED is on when field power is applied to the module.
The green OK LED is on when backplane power is present to the module.
Diagnostics
The module reports the presence of any overloaded points to the system on a per-
module basis. Amber LEDs indicate the overload conditions on a per-point basis.
Once the overload condition is removed, normal operation is resumed.
