General Electric IC693CPU350 CPU 350 Module

Overview

The General Electric IC693CPU350 CPU 350 Module is a high‑performance processor designed for the FANUC Series 90‑30 PLC platform. This single‑slot CPU delivers reliable real‑time control, efficient program execution, and broad system compatibility for industrial automation and process‑control applications.

Functional Design

The GE IC693CPU350 is powered by an 80386EX processor running at 25 MHz and includes 32 KB of user memory (RAM + Flash). This architecture supports fast logic execution and stable data handling across a wide range of automation tasks. The module integrates an RS‑485 serial port for flexible communication and maintains full compatibility with all Series 90‑30 components.

Operating on 5 VDC at 670 mA, the IC693CPU350 supports more than 2000 timers and counters, enabling precise sequencing and timing control. In typical configurations, it can support up to 20 DSM314 modules, although actual capacity depends on memory allocation, datagram usage, and program/configuration storage. Separating program and configuration files can improve overall performance.

With a processing speed of 0.9 ms per 1K Boolean instructions, the module provides dependable performance for both discrete and process‑control environments.
