The GE-Emerson IC670MDL331 Field Control Discrete Output Module uses power from the power supply in the Bus Interface Unit. An external source of AC power must be provided to power the loads.
Intelligent processing for the module is performed by the Bus Interface Unit or elsewhere in the system. This includes configuring features such as output default and fault reporting. The module has 8 bits (one byte) of discrete output data. A Bus Interface Unit is required to obtain this output data from the host and/or local processor.
Individual LEDs (logic side), visible through the transparent portion of the module top, indicate the on/off status of each output. The abbreviations F1/PWR, F2/PWR, F3/PWR, and F4/PWR refer to the Fuse OK LED for each of the four groups.
