GE Series 90-70 IC697

The GE Series 90-70 IC697 family is a modular PLC system designed for larger control applications using rack-mounted processors, I/O, power supplies, and communication modules. Its architecture supports high-capacity discrete and analog I/O, specialty functions, network interfaces, and expansion racks connected to a central processor. Series 90-70 systems were applied in process control, power generation, material handling, and large machine automation where higher I/O counts and coordinated control were required. IC697 replacement modules are commonly used to maintain installed systems without changing the original rack or application structure. Selection normally depends on exact catalog number, rack position, electrical characteristics, interface type, and compatibility with the existing CPU and system configuration.
