Product Overview
The GE IC697CPU772RR is a high-performance central processing unit (CPU) module from GE Fanuc’s Series 90-70 PLC platform, engineered for mission-critical industrial automation. Utilizing an 80C186 microprocessor clocked at 12 MHz and equipped with 512 KB RAM + 256 KB non-volatile flash memory , this module delivers rapid Boolean instruction execution (0.4 μs) and robust real-time control. It seamlessly integrates into VME-based PLC racks, managing up to 8,000 analog I/O points and 512 discrete I/O points . Configuration is entirely software-driven via GE’s Proficy ME or Windows tools, eliminating error-prone physical switches and enhancing reliability in vibration-intensive environments. As a core component, the IC697CPU772RR ensures operational continuity through battery-backed memory (lithium battery IC697ACC701) and advanced security protocols, making it ideal for complex automation systems requiring fail-safe performance .
