PRODUCT INFORMATION
Product Overview
The General Electric IC670MDL240 is a sixteen-point discrete input module for the Field Control I/O station. This module operates as an expansion unit alongside a Bus Interface Unit. The Bus Interface Unit supplies backplane power and manages intelligent processing duties for the module. It draws a maximum of 77 mA of current from the host power supply. Input filtering uses an internal network of resistors and capacitors to establish switching thresholds.
Field devices connect across sixteen discrete inputs arranged in a single electrical group. The module accepts nominal 120 VAC signals across an operating voltage range of 0 to 132 VAC. An external 120 VAC power source must supply voltage to the connected field signaling devices. Individual status LEDs indicate active logic states, while a power LED indicates backplane power reception.
