Introduction
Is your Series 90-30 PLC running out of I/O capacity? The IC693CHS392 from GE is a 10-slot expansion baseplate that solves this problem by adding ten additional slots for standard I/O and option modules. Formerly manufactured by GE Fanuc and now under Emerson Automation, this baseplate connects to your CPU baseplate via a 25-pin D-shell connector, extending your control system’s reach. However, please note that this product is discontinued. Verify current lifecycle status and availability with SpareTechPLC before ordering.
Technical Specifications
Understanding the key specs helps you plan your expansion correctly. The baseplate operates on 5 VDC and draws 150 mA. It provides ten I/O slots and one power supply slot, but no CPU slot. The maximum expansion cable length is 50 feet (15 meters) — exceeding this may cause the CPU to not recognize the baseplate. The 25-pin D-shell female connector on the right side ensures reliable interconnection. Dimensions are 443 x 142 x 130 millimeters, and it supports panel mounting.
Compatibility and Integration
The IC693CHS392 works with Series 90-30 PLCs. It supports CPUs 331, 340, and 341 with up to four baseplates interconnected, and CPU 350 and higher with up to seven. Intelligent modules like PCM, ADC, BEM330, and CMM are not compatible with this expansion baseplate; they must be installed on the CPU baseplate. This baseplate is for indoor use only and should be protected from water, dust, and heat.
Installation and Setup
Mount the baseplate on a panel using the mounting tabs on the left and right sides. Ensure proper grounding to minimize electrical noise. Connect the expansion cable to the 25-pin D-shell connector, keeping the length under 15 meters. The open architecture allows easy access during installation and replacement. Always follow local electrical codes and the manufacturer’s guidelines.
Maintenance and Reliability
Since this product is discontinued, maintenance focuses on periodic inspection of connections and the environment. Keep the baseplate clean and dry, and check for loose cables or corrosion. For safety, never disassemble or repair internal components; consult a qualified technician. If you need a replacement, SpareTechPLC can help you find suitable alternatives or verify availability.
