Description
Product Description
The IC697CPU771 is a robust central processing unit module for the GE Fanuc Series 90-70 PLC family. Designed to provide reliable processing, memory management, and communication capabilities, it is ideal for medium-to-large automation systems that demand stable and consistent performance.
Equipped with an Intel 80386 (or 80C816DX) microprocessor, the IC697CPU771 operates at 12–20 MHz, delivering fast execution of ladder logic and advanced control programs. It supports up to 512 KB of battery-backed RAM for user programs and data storage, along with discrete and analog I/O memory for efficient system operation.
The module includes built-in serial communication ports (RS-232/RS-485) for integration with supervisory systems, remote I/O, or other PLC modules. Its single-slot form factor fits standard Series 90-70 racks, with LED indicators for module status, RUN, and output enable, ensuring clear operational feedback.
