The GE-Emerson IC670MDL740 Field Control Discrete Output Module includes outputs that switch loads to the positive side of the DC supply, supplying current to the load. The module is powered by the bus interface unit (BIU) power supply. An external source of DC power must be provided for the switches that power the loads. Within the module, the external power supply is connected to a 5A fuse. During operation, the module monitors this power to be sure it is above 9.8VDC. If not, it is interpreted as a fault by the BIU.
Individual LEDs (logic side), visible through the transparent portion of the module top, indicate the on/off status of each output. The PWR LED is on when field and backplane power are present and the module fuse is not blown.
Intelligent processing for the module is performed by the BIU 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 BIU is required to obtain this output data from the host and/or local processor.
