This 5-slot rack base expansion adds I/O capacity to Series 90-30 PLC systems. The GE IC693CHS398J connects to the main CPU rack through a shielded expansion cable. Five module slots accept any combination of discrete, analog, or specialty I/O modules. Consequently, automation engineers can expand system capacity without replacing existing hardware.
Technical Specifications of the 5 Slot Rack Base Expansion
The GE IC693CHS398J measures 350 mm in width and 110 mm in height. Its depth reaches 130 mm for standard panel or rack mounting. The base weighs approximately 1.2 kg including the backplane and mounting brackets. A single status LED indicates power availability and backplane communication. The rear side features a 50-pin expansion connector for cable attachment. This design stores no energy whatsoever. Therefore, the base contains no capacitors, batteries, or any other storage elements.

Functional Features and System Expansion
The GE IC693CHS398J extends the I/O count beyond the main CPU rack limits. You can install any standard Series 90-30 module in any of the five slots. The base automatically communicates with the CPU through the expansion cable. Each slot provides both 5V and 24V DC power to inserted modules. Consequently, this rack base supports up to 128 additional I/O points per expansion.
Installation and System Configuration
You must mount this rack base on a flat panel using the integrated mounting slots. The GE IC693CHS398J requires a shielded expansion cable for connection to the main rack. A 24V DC external power supply provides field power for I/O modules. The CPU automatically recognizes all modules in the expansion rack after configuration. Always verify cable routing to avoid electrical noise from motor cables.
Maintenance and Operational Benefits
Because the GE IC693CHS398J stores no energy, it requires no discharge time before handling. Technicians can install or remove modules without powering down the entire system. The open architecture allows easy access to module status LEDs and wiring. Consequently, this rack base offers a cost-effective expansion solution for growing automation systems.
