GE Fanuc IC697CPX772 Series 90-70 PLC CPU Module

The GE Fanuc IC697CPX772 is a single-slot high-performance central processor unit for the Series 90‑70 VME-based PLC control platform. Equipped with a 96MHz 80486DX4 embedded processor, it cyclically executes automation control logic, processes complex floating-point calculations and manages all rack I/O data exchange for medium and large-scale industrial projects.

This CPU integrates 512KB battery-backed RAM and 256KB non-volatile flash memory to protect programs and configuration data during power loss. It features one RS232 and dual RS485 serial ports supporting multiple industrial protocols, offering flexible interconnection with HMIs, remote controllers and field devices, widely supplied as spare parts for plant system maintenance and upgrade projects.
