Product Overview
When your Series 90-30 PLC system needs more I/O capacity, the GE IC693CHS392 expansion baseplate delivers a reliable solution. This 10-slot expansion baseplate, formerly by GE Fanuc and now under Emerson Automation, provides ten I/O slots, one power supply slot, and a 25-pin D-shell female expansion connector. Designed for indoor panel mounting, it supports up to seven CPUs depending on the model.
Technical Specifications Breakdown
The IC693CHS392 operates on 5 Volts DC with a current rating of 150 milliAmps. Its internal power consumption is 150 mA at 5 VDC. The baseplate measures 443 x 142 x 130 millimeters (17.44 x 12 x 5.59 inches). It has no CPU slots, as CPUs reside in the main baseplate. The maximum expansion cable length is 50 feet (15 meters).
Industry Applications
In manufacturing lines requiring distributed I/O, the IC693CHS392 allows you to place I/O modules closer to sensors and actuators. For example, in a packaging plant, you can mount an expansion baseplate near the conveyor system, reducing wiring complexity. This baseplate also suits process control applications where additional analog or specialty modules are needed without overloading the CPU baseplate.
Installation & Setup Guidance
Mount the IC693CHS392 on a panel using the provided mounting tabs on the left and right sides. Ensure proper grounding to protect modules and minimize electrical noise. Connect the expansion cable from the CPU baseplate to the 25-pin D-shell female connector on the right side of the baseplate. The cable length must not exceed 50 feet (15 meters) for reliable communication. Install the power supply module in the dedicated slot, then insert I/O modules into slots 1-5 and option modules into slots 6-10.
Compatibility & Integration
The IC693CHS392 is compatible with Series 90-30 PLCs, specifically CPUs 331, 340, 341 (up to four baseplates) and CPU 350 and higher (up to seven baseplates). Intelligent modules like PCM, ADC, BEM330, and CMM are not supported on expansion baseplates—install them on the CPU baseplate. The baseplate supports standard I/O modules and option modules.
Selection Guide & Purchasing Advice
Before ordering, verify your CPU model to determine the maximum number of expansion baseplates allowed. Ensure you have the correct power supply module for the expansion baseplate. The IC693CHS392 is discontinued/obsolete, so check current availability with SpareTechPLC. We stock this baseplate and can help you find compatible modules.
Frequently Asked Questions
Q: Can I use the IC693CHS392 with any Series 90-30 CPU?
A: It works with CPUs 331, 340, 341 (up to four baseplates) and CPU 350 and higher (up to seven baseplates).
Q: What is the maximum cable length between baseplates?
A: 50 feet (15 meters). Exceeding this may cause the expansion baseplate not to be recognized.
Q: Can I install intelligent modules like PCM or CMM in this baseplate?
A: No. Intelligent modules must be installed in the CPU baseplate.
Q: What power supply does the IC693CHS392 require?
A: It requires a power supply module installed in the dedicated slot, providing 5 VDC at 150 mA.
Q: Is this baseplate still in production?
A: No, it is discontinued/obsolete. Contact SpareTechPLC for availability.
