Product Overview
The GE IC697MDL671 Discrete Input Module is a high-performance industrial digital input module designed for the GE Fanuc Series 90-70 Programmable Logic Controller (PLC) platform. Built to provide accurate and reliable acquisition of discrete field signals, the IC697MDL671 serves as a critical interface between industrial input devices and the PLC processor, enabling real-time machine monitoring, process control, and automated decision-making.
As part of the proven Series 90-70 I/O family, the module continuously collects ON/OFF signals from field equipment such as proximity sensors, limit switches, push buttons, selector switches, relay contacts, emergency stop circuits, pressure switches, photoelectric sensors, and other industrial control devices. These signals are transmitted through the high-speed PLC backplane to the CPU, where they are processed by the user program to control machinery, monitor production status, and execute automation logic.
The IC697MDL671 is engineered to operate reliably in demanding industrial environments characterized by electrical noise, vibration, temperature fluctuations, and continuous production cycles. Its rugged industrial construction provides excellent signal integrity, minimizes maintenance requirements, and supports long-term system reliability.
With compact dimensions of 200 × 40 × 150 mm and an approximate weight of 0.77 kg, the module is easy to install in standard Series 90-70 racks and is well suited for both new automation systems and modernization projects.
The GE IC697MDL671 is widely used in factory automation, power generation, oil and gas processing, mining operations, chemical manufacturing, water and wastewater treatment, pharmaceutical production, food and beverage processing, packaging equipment, logistics centers, and material handling systems.
