The GE-Emerson IC670MDL644 Field Control Discrete Input Module receives power from the BIU for its own operation. An external 24VDC supply is needed to power the input devices. Individual LEDs (logic side), visible through the transparent portion of the module top, indicate the on/off status of each input. The PWR LED is on when field and backplane power are present.

Intelligent processing for this module is performed by the BIU or elsewhere in the system. This includes configuring features such as input defaults and fault reporting. The module has 16 bits (two bytes) of discrete input data. A BIU is required to provide this input data to the host and/or local processor.
