EMERSON IC670MDL640 24VDC Positive/Negative Discrete Input Module

The positive/negative input module provides a single group of 16 discrete inputs, which may be driven by positive or negative logic. 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 Bus Interface Unit 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 Bus Interface Unit is required to provide this input data to the host and/or local processor.
