Product Overview
When an existing Series 90-30 system requires a baseplate replacement, the GE IC693CHS391 modular CPU baseplate provides a direct, reliable drop-in solution. Manufactured by GE Fanuc, this 10-slot baseplate houses the CPU, power supply, and I/O modules, forming the core of a Series 90-30 PLC system. Designed for panel mounting, the IC693CHS391 supports one CPU in slot 1 and up to nine I/O or option modules in slots 2-10.

Discontinued/Obsolete |
The GE IC693CHS391 baseplate draws 420 mA at 5 V DC and includes a 25-pin female connector for expansion or remote baseplates. It supports panel mounting and a default rack address of 0, configurable via programming software.
Applications & Use Cases
In a typical upgrade scenario, the IC693CHS391 replaces a failed or outdated baseplate in a Series 90-30 installation used for discrete manufacturing, packaging lines, or material handling. Its 9 I/O slots accommodate analog or digital modules, while the dedicated CPU slot hosts a 90-30 CPU (e.g., IC693CPU313, IC693CPU363). The expansion port allows connection to up to 7 additional baseplates, increasing I/O capacity without redesigning the control cabinet.
Installation & Setup Guidance
Mount the IC693CHS391 baseplate onto a panel using screws through the provided mounting holes. Install the power supply module in the leftmost (unnumbered) slot. Insert the CPU into slot 1 and I/O modules into slots 2-10. Connect expansion cables using the 25-pin female connector on the right side; cable length must be less than 700 feet. Ensure the environmental temperature stays within the specified range and avoid exposure to water, dust, or chemicals.
Compatibility & Integration
The IC693CHS391 integrates with any Series 90-30 PLC system. It supports one CPU baseplate per system; additional baseplates are expansion or remote I/O types. Connection to a personal computer requires a PCI card. The baseplate cannot operate standalone—it must be paired with a PLC CPU or PC interface. Only one CPU module is permitted per system, and slot 1 can also accept special option modules like the FIP Bus Remote I/O scanner.
Selection Guide & Purchasing Advice
When replacing an existing baseplate, verify that the CPU and I/O modules are compatible with the IC693CHS391. The baseplate is discontinued, so sourcing a genuine unit from a reliable supplier like UBEST Automation ensures long-term operation.
