GE IC693CPU350-CG Single Slot CPU Module

Technical Specifications and Processing Power

This single slot CPU module serves as the brain for GE Series 90-30 PLC systems. The GE IC693CPU350-CG executes logic programs with consistent scan cycle performance. You can rely on this processor for demanding machine control applications. Its compact design occupies only one slot in the base rack. The module weighs approximately 0.5 kilograms. Its dimensions measure 14 cm in height, 4 cm in width, and 12 cm in depth.

Memory Management and Data Retention

The module includes a factory-installed lithium battery for data backup. This battery preserves your application logic and register values during power loss. You should replace the battery every five years for reliable operation. The GE IC693CPU350-CG stores its user program in CMOS RAM. A secondary flash memory holds the operating system firmware permanently. The module also supports an optional EPROM memory cartridge. You can use this cartridge for program backup or remote copying.

Connectivity and Communication Ports

You will find two built-in communication ports on the front panel. Port 1 uses RS-485 for programming or operator interface connections. Port 2 supports RS-232 for point-to-point data exchange. The module also includes a dedicated coprocessor port for high-speed I/O. Each port operates independently without interrupting the scan cycle. You can configure baud rates from 300 to 19.2 Kbps easily.

Installation and Operational Guidelines

You must insert this CPU into the first slot of the expansion rack. The backplane provides 5V DC power to the module. Removing the battery will clear all stored user data immediately. Therefore, you should backup your program before any battery change. The module powers up automatically when the system receives voltage.
