Product Overview

The GE IC693CPU350 is a mid-range, high-efficiency processor designed to serve as the control intelligence for the Series 90-30 Programmable Logic Controller (PLC) platform. Powered by an Intel 80386EX microprocessor clocked at 25 MHz, this module is optimized for discrete manufacturing and process control applications that require a balance of speed and reliability.

As a single-slot module, the IC693CPU350 integrates seamlessly into the backplane, managing all I/O communication and logic execution. It features 32KB of configurable user memory, providing ample space for ladder logic, C-programming blocks, and system configuration data. This CPU is a legacy powerhouse, known for its deterministic performance and low power consumption in demanding industrial environments.

Control Logic and System Flexibility

The IC693CPU350 stands out for its flexibility in memory management. It allows users to partition the 32KB of memory between register data and program logic, supporting complex instructions and floating-point math through C-block programming. This makes it particularly effective for applications involving motion control or PID loop regulation.

Designed for high-availability systems, the CPU supports advanced diagnostics and real-time monitoring through GE Proficy Machine Edition or legacy Logicmaster 90 software. The integrated RS-485 port facilitates easy connection to Hand-Held Programmers or HMI interfaces. Furthermore, its low-power architecture reduces heat dissipation within the PLC rack, contributing to a longer lifespan of adjacent I/O modules. Whether deployed in a standalone machine or as part of a larger Distributed Control System (DCS), the IC693CPU350 delivers the consistent, millisecond-accurate execution required for modern industrial infrastructure.
