Description
Product Description
The IC697MDL671 is a high-voltage discrete input module engineered for the GE Fanuc Series 90-70 PLC family. It offers 32 positive logic input points operating at 48 VDC, providing reliable digital signal acquisition from field devices such as pushbuttons, limit switches, and proximity sensors.
Equipped with opto-isolated inputs, the IC697MDL671 delivers excellent noise immunity for stable operation in electrically noisy environments. It connects via two 20-pin field connectors and integrates seamlessly into standard Series 90-70 racks. The module is designed for high reliability and continuous operation in industrial applications.
This module supports a wide range of input devices, making it suitable for machine control, process monitoring, and multi-rack PLC systems where higher voltage signal acquisition is required.
