GE IC693CPU351-EK CPU Module | Series 90-30 PLC Processor

Programmable logic controllers require robust processing power for complex automation tasks. The GE IC693CPU351-EK CPU module delivers this core functionality for Series 90-30 systems. This module serves as the central processing unit for the entire control system. It executes user programs and manages I/O data exchange efficiently.

Technical Architecture and Specifications

This CPU module features a standard Series 90-30 form factor for rack-based installation. Its dimensions measure 12.5 cm in width and 11.4 cm in height. The GE IC693CPU351-EK weighs approximately 0.4 kilograms for secure mounting. It interfaces with the system backplane via a 48-pin card-edge connector. This connector provides power and communication to all I/O modules.

The internal assembly contains a single integrated circuit board with multiple processors. One processor handles logic execution, while another manages communication tasks. Engineers will note the inclusion of 240 KB of user program memory. This memory stores ladder logic, configuration data, and register values. The module also features 20 KB of register memory for data storage.

Communication and Connectivity

The GE IC693CPU351-EK provides built-in communication ports for system integration. It includes one RS-232 port for programming and one RS-485 port for networking. For operator interface, it supports connection to GE Fanuc operator panels directly. The module also accommodates an optional memory expansion cartridge for additional storage.
