GE IC693CHS392 Series 90-30 10-Slot Expansion Baseplate

Product Overview

When your control system requires additional I/O capacity beyond the CPU baseplate, the GE IC693CHS392 expansion baseplate provides a reliable solution. Part of the Series 90-30 PLC family, this baseplate offers ten I/O slots and one dedicated power supply slot, enabling seamless system expansion. Designed for indoor panel mounting, it supports standard Series 90-30 I/O and option modules, making it a versatile choice for growing automation needs.

Technical Specifications

The IC693CHS392 operates on 5 Volts DC with a current draw of 150 milliAmps. It features ten I/O slots and one power supply slot, with no CPU slot. Expansion is facilitated via a 25-pin D-shell female connector, supporting a maximum expansion cable length of 50 feet (15 meters). The baseplate dimensions are 443 x 142 x 130 millimeters (17.44 x 12 x 5.59 inches). It is compatible with CPUs 331, 340, and 341 (up to four baseplates) and CPU 350 and higher (up to seven baseplates). Note that intelligent modules like PCM, ADC, BEM330, and CMM are not supported in this expansion baseplate.

Industry Applications

This expansion baseplate is ideal for manufacturing lines requiring distributed I/O points, such as automotive assembly or packaging systems. By adding the IC693CHS392, engineers can centralize control while physically separating I/O modules for better organization and reduced wiring complexity. It also suits process control environments where additional specialty modules are needed without overloading the CPU baseplate.

Installation Guide

Mount the IC693CHS392 baseplate on a panel using the provided mounting tabs on the left and right sides. Ensure the expansion cable does not exceed 15 meters to maintain reliable communication with the CPU baseplate. Proper grounding is essential to minimize electrical noise and protect modules. This baseplate is for indoor use only and should be kept away from dust, heat, and water splashes.

Maintenance & Reliability

Regularly inspect the baseplate for secure connections and clean contacts. Since the IC693CHS392 is discontinued, verify availability with BluePLC Industrial before ordering. For long-term reliability, ensure the power supply module is correctly seated and the expansion cable is not damaged. Environmental protection against dust and moisture extends service life.

Compatibility & Integration

The IC693CHS392 integrates with Series 90-30 PLCs using CPUs 331, 340, 341, 350, and higher. It supports up to seven CPUs in a multi-baseplate configuration. The 25-pin D-shell expansion port allows daisy-chaining additional baseplates. Note that intelligent modules (PCM, ADC, BEM330, CMM) must remain on the CPU baseplate. The baseplate is compatible with standard I/O and option modules installed in slots 1-5.

Selection Guide & Purchasing Advice

Before purchasing the IC693CHS392, confirm your CPU model and the maximum number of baseplates supported. Verify the expansion cable length stays within 15 meters. Since this product is discontinued, contact BluePLC Industrial to check current stock and find suitable replacements if needed.
