GE IC693CHS392 Expansion Baseplate: Key Specs & Review
GE IC693CHS392 Expansion Baseplate Overview
The GE IC693CHS392 is a 10-slot expansion baseplate for the Series 90-30 PLC platform. Formerly manufactured by GE Fanuc and now under Emerson Automation, this module supports system expansion by adding up to ten I/O or option modules. Engineers use this baseplate to increase the central controller's I/O capacity and implement specialty functions. The baseplate features one power supply slot and one expansion port using a 25-pin D-shell female connector.

Compatibility and Installation
The IC693CHS392 works with standard Series 90-30 I/O modules and option modules. However, intelligent modules such as PCM, ADC, BEM330, and CMM are not compatible with this expansion baseplate and require installation on the CPU baseplate. The baseplate allows interconnection of up to seven CPU units depending on the CPU model. Proper grounding is essential to protect modules and reduce electrical noise. The baseplate mounts via tabs on the left and right sides. Use this baseplate in indoor environments only, away from dust and moisture.
Practical Considerations
Since the IC693CHS392 is discontinued, buyers should verify availability and consider alternatives. The 10-slot design provides ample space for I/O expansion while maintaining a compact footprint. The 25-pin expansion port ensures reliable communication between baseplates. Operators must not exceed the 15-meter cable length to avoid configuration errors. The baseplate also includes a DIP switch for configuration.
