Product Introduction
The GE IC693CPU331 is a powerful and compact single-slot central processing unit (CPU) module designed for use within the GE Fanuc Series 90-30 PLC family. Engineered to deliver reliable and consistent control performance, the IC693CPU331 provides a balance between affordability and functionality for industrial automation applications that require mid-range processing power. It occupies only one slot in the Series 90-30 base, allowing for efficient use of space while leaving room for various I/O modules, communication interfaces, and specialty units.
This CPU supports floating-point math, has battery-backed memory for data retention, and is capable of executing up to 32KB of user logic. Its design includes a built-in serial port (RS-232), real-time clock, and flexible memory management—making it ideal for OEMs, systems integrators, and facility engineers who require a dependable control solution without the footprint of larger controllers.
