GE IC693CPU352 – Series 90-30 High-Performance Single-Slot CPU Module

In stock

Product Introduction:

The IC693CPU352, manufactured by GE Fanuc (Emerson Automation), is a high-performance CPU module in the Series 90-30 PLC family. Designed as a single-slot “Turbo CPU,” it leverages a 32-bit 80386EX processor to deliver fast logic execution, floating-point math, and extensive I/O control for medium-to-large hybrid discrete/analog automation systems. Integrated with multiple serial ports, a real-time clock, and support for advanced communication modules, it serves as the core controller for complex industrial applications requiring high reliability and processing power.
