IC200MDD842
Mixed Module, Output 24 V DC Pos. Logic 0.5A Grouped w/ESCP 16 Points
/ Input 24 V DC Pos/Neg Logic Grouped 16 Points
Discrete input/output module IC200MDD842 provides one group of 16 discrete
outputs w/ESCP and two groups of 8 discrete inputs. The outputs are positive or
sourcing type outputs. Each point has electronic over-current protection and short
circuit protection, and generates a fault if either condition exists. They switch the
loads to the positive side of the DC supply and thus supply current to the loads. 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.

Note:
Negative-logic functionality requires module version IC200MDD842B or
higher.
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 NILU. The
module provides 16 bits of discrete input data and receives 16 bits of discrete
output data.
LED Indicators
Individual green LEDs indicate the on/off state of the output points and input
points. Operation of the output LEDs is 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.
