GE IC693CHS392 10-Slot Expansion Baseplate for Series 90-30 PLC

Product Introduction

As industrial automation systems evolve, the need for scalable I/O capacity becomes critical. The GE IC693CHS392, part of the Series 90-30 PLC platform, addresses this challenge by providing a robust 10-slot expansion baseplate. Formerly manufactured by GE Fanuc and now under Emerson Automation, this baseplate enables engineers to expand their control system's I/O points and integrate specialty functions without replacing the central controller. Designed for indoor environments, the IC693CHS392 supports panel mounting and ensures reliable performance in demanding industrial settings.

Technical Specifications Breakdown

The IC693CHS392 operates at 5 Volts DC with a current draw of 150 milliAmps, ensuring low power consumption while powering up to ten I/O modules. It offers ten I/O slots, one power supply slot, and one expansion port with a 25-pin D-shell female connector. The maximum expansion cable length is 50 feet or 15 meters, critical for maintaining signal integrity across interconnected baseplates. Dimensions are 443 x 142 x 130 millimeters (17.44 x 12 x 5.59 inches), and the baseplate supports panel mounting only. It is compatible with CPUs 331, 340, 341, 350, and higher, allowing up to seven baseplates in a system. Note that intelligent modules like PCM, ADC, BEM330, and CMM must be installed on the CPU baseplate, not the expansion baseplate.

Industry Applications

In manufacturing plants requiring distributed I/O, the IC693CHS392 enables cost-effective expansion. For example, a bottling facility can use this baseplate to add sensors and actuators in a remote location, connected via the 15-meter expansion cable. Similarly, in water treatment systems, it allows integration of analog and digital modules for monitoring flow and pressure. This flexibility reduces downtime during upgrades and simplifies maintenance.

Installation & Setup Guidance

Mount the IC693CHS392 on a panel using the provided tabs on the left and right sides. Ensure proper grounding to minimize electrical noise and protect modules. Connect the expansion cable from the CPU baseplate to the 25-pin D-shell female connector, keeping the cable length under 15 meters. Install the power supply module in the dedicated slot, then insert I/O modules into slots 1-5 for standard I/O or option modules. Verify compatibility with your CPU model before commissioning.

Compatibility & Integration

The IC693CHS392 is compatible with Series 90-30 CPUs 331, 340, 341, 350, and higher. It supports up to seven baseplates when using CPU 350 or higher, and up to four with CPUs 331, 340, and 341. The expansion baseplate works with standard I/O modules and option modules but excludes intelligent modules like PCM, ADC, BEM330, and CMM. For systems requiring those, install them on the CPU baseplate.

Selection Guide & Purchasing Advice

Before purchasing the IC693CHS392, verify your CPU model to determine the maximum number of baseplates supported. Ensure the expansion cable length does not exceed 15 meters.
