Mixed Module Output Relay 2.0 A per Pt Isolated 8 Points /
Input 120 V AC Isolated 8 Points
Discrete input/output module IC200MDD849 provides 8 isolated discrete inputs
and 8 relay outputs. Inputs are positive logic or sourcing-type inputs; they receive
current from AC input devices and return the current on the common. Each input
has its own return. Outputs are individually-isolated relays which can drive a
maximum of 2 A per output. These are Form A relay outputs where the contact is
closed when the host CPU is active and the corresponding output logic bit is “1”.

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 8 bits of discrete input data and receives 8 bits of discrete output data.
LED Indicators
Individual green LEDs indicate the On/Off states of the output points and input
points. Operation of the output LEDs is logic driven and independent of the load
conditions.
The green OK LEDs are ON when backplane power is present to the module.
