Core Function and Integration
The GE IC670MDL640 is a versatile 16-point discrete input module for distributed I/O systems. This unit, part of the GE Fanuc legacy now under Emerson, belongs to the Field Control series. It reliably senses the on/off status of field devices like switches and sensors. Consequently, it provides critical digital data to the central control system for logic processing.
Electrical Characteristics and Sensing
This module accepts a wide input voltage range from 0 to 30 VDC, with 24 VDC as nominal. Furthermore, it operates with positive or negative logic for flexible wiring configurations. Each input channel requires a low signal current of only 7.5 mA at 24 VDC. Therefore, it minimizes the load on field devices and simplifies power supply design.
