Description
Product Description
The GE IC697CGR772 is a dual-bus CPU module engineered for the GE Fanuc Series 90-70 PLC family. Designed for large-scale industrial automation, this high-performance processor supports hot-standby operation, extensive memory, and advanced multitasking for complex control applications. It delivers reliable program execution across thousands of I/O points and integrates robust communication interfaces, making it ideal for demanding process and manufacturing environments.
Equipped with a 32-bit 80486DX4 microprocessor running at 96 MHz, the IC697CGR772 provides fast Boolean execution (0.4 μs per function), precise floating-point calculations, and a scan time of approximately 5.9 ms. Its memory includes 512 KB CMOS RAM for program storage and support for up to 8,000 analog I/O points, ensuring high scalability. Dual communication ports (1 × RS-232, 2 × RS-485) with SNP protocol support facilitate integration into plant networks.
