GE IC693CHS397K Industrial Control System Base

Rack Architecture and Physical Configuration

The GE IC693CHS397K provides a 10-slot baseplate for the Series 90-30 programmable controller family. It supports CPU modules, power supplies, and I/O modules in a single integrated assembly. This base measures 12.5 cm in height, 42.5 cm in width, and 12.9 cm in depth. It weighs approximately 1.9 kg, offering substantial structural integrity for industrial mounting applications.

This unit features a passive backplane that distributes power and data signals to all installed modules. The backplane accommodates up to 10 modules arranged in a single row for straightforward system configuration. Engineers can populate slots with any combination of Series 90-30 compatible components. This flexibility allows users to build custom control systems tailored to specific application requirements.

Interface Connections and Slot Architecture

The IC693CHS397K includes ten individual slot connectors that provide both power and communication pathways. Each slot features keying mechanisms that prevent incorrect module insertion during installation. The baseplate includes two mounting tabs on each side for secure panel attachment. A DIN rail mounting option also accommodates applications requiring quick removal and repositioning.

The backplane design supports hot insertion of select modules for maintenance without system shutdown. This capability reduces downtime when replacing faulty components in critical applications. The base also provides grounding terminals for connecting chassis ground to protective earth systems.

Power Distribution and Energy Management

This baseplate distributes 5 VDC and 24 VDC power from the power supply module to all occupied slots. It incorporates power filtering components that reduce electrical noise on the backplane. The passive design includes overcurrent protection circuitry that isolates faults to individual slots. This isolation prevents a single module failure from affecting the entire system.

Technical Specifications

System Integration and Compatibility

The IC693CHS397K accepts all Series 90-30 CPUs, including the IC693CPU374 and IC693CPU363 models. It supports power supplies such as the IC693PWR322E and IC693PWR321 for various power requirements. Users can combine this base with input modules like IC693MDL752F and output modules for complete system configurations. This base replaces earlier versions including the IC693CHS397 with enhanced thermal management features.
