GE IC693CHS392 – 10-Slot Expansion Baseplate

The IC693CHS392 is a 10-slot expansion baseplate designed for the Series 90-30 Programmable Logic Controller (PLC) platform. Manufactured by GE Fanuc, now under Emerson Automation, this baseplate plays a key role in enhancing system performance by enabling the integration of additional I/O modules. It offers flexibility by supporting up to ten I/O modules, one power supply module, and an expansion port, making it an essential part of the Series 90-30 control system.

Key Features

• Manufacturer: GE Fanuc (Emerson Automation)
• Model: IC693CHS392
• Type: 10-slot Expansion Baseplate
• Function: Expands system I/O capacity and allows module interconnection.
• Compatibility: Works with Series 90-30 PLCs, including CPUs 331, 340, 341, and 350.
• Mounting: Panel mounting using provided mounting tabs for secure installation.

Technical Specifications

The IC693CHS392 backplane is essential for expanding the I/O capacity of your system. It provides ten slots for standard I/O and option modules, as well as a power supply slot for the necessary power distribution. Importantly, this baseplate allows the connection of up to seven expansion baseplates, depending on the CPU model. For example, CPUs 331, 340, and 341 support up to four interconnected baseplates, while CPUs 350 and higher can manage up to seven.

Applications

This expansion baseplate is designed for systems requiring a significant increase in I/O points. It is particularly useful for projects involving large-scale automation, where more modules are necessary for system flexibility and performance. Additionally, this baseplate is fully compatible with Series 90-30 PLCs. However, when interconnecting multiple baseplates, make sure the total cable length does not exceed 50 feet (15 meters). Exceeding this limit could prevent the system from recognizing the connected baseplates, potentially causing the entire configuration to fail.

Furthermore, it is important to note that certain intelligent modules, such as the PCM, ADC, BEM330, and CMM modules, must be installed directly on the CPU baseplate, not on the expansion baseplate. This ensures proper functionality and system integrity.
