GE Fanuc IC693CPU351 Series 90-30 PLC Processor Module

The GE Fanuc IC693CPU351 is a high-performance 25 MHz CPU for Series 90-30 PLCs. It features 240KB user memory, three serial ports, and supports up to 2048 I/O points, providing robust control for complex industrial automation and DCS applications.

Product Overview

The General Electric IC693CPU351 acts as a high-performance computational core for the Series 90-30 Programmable Logic Controller (PLC) family. This module integrates an 80386EX processor operating at 25 MHz, significantly boosting execution speeds for complex logic and floating-point math compared to entry-level units. Designed for scalability, the IC693CPU351 manages large-scale I/O architectures while maintaining a compact footprint within a standard 90-30 baseplate.

Core Functional Capabilities

  • Advanced Memory Architecture: This processor provides 240 KB of user-configurable memory, which accommodates extensive ladder logic programs, register data, and diagnostic storage.
  • Expanded I/O Capacity: The module supports up to 2048 discrete inputs/outputs and 32,640 analog channels, making it suitable for sophisticated distributed control systems (DCS).
  • Serial Communications: It features three integrated serial ports that facilitate simultaneous connections to programming terminals, HMI devices, and peripheral sensors via SNP/SNP-X protocols.
  • High-Speed Logic Execution: By utilizing an optimized 25 MHz clock speed, the CPU handles over 2000 timers and counters with minimal scan-time impact.
