Output Module, 24 V DC Positive Logic 0.5 A, w/ESCP 16 Points
Discrete output module IC200MDL741 provides one group 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.

Q
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 16 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.
