The GE Fanuc IC697MDL653 is a high-density, 32-point discrete input module designed for the GE Fanuc Series 90-70 programmable logic controller (PLC) system. It is engineered to monitor industrial-grade, 24V DC field devices—such as proximity switches, limit switches, and push buttons—and report their status to the CPU. This module provides a reliable solution for consolidating a large number of digital inputs in a single slot of the PLC rack.
