The General Electric IC693CHS391 is a 10-slot modular CPU baseplate designed for the Series 90-30 Programmable Logic Controller (PLC) family. Serving as the primary rack (Rack 0) in a Series 90-30 system, this baseplate provides the necessary backplane communication and power distribution for the CPU, power supply, and various I/O or option modules.

Features

• 10-slot configuration: 1 dedicated power supply slot, 1 dedicated CPU slot, and 9 slots for I/O or option modules.
• Modular design allowing for flexible system expansion.
• Integrated 25-pin female connector for expansion or remote baseplate connectivity.
• Supports system configurations with expansion or remote baseplates up to 700 feet away from the CPU rack.
• Local electronic backplane provides 5 VDC power to all installed modules.

Applications

• Automotive manufacturing for robot control and process monitoring.
• Food and beverage production line automation.
• Chemical and pharmaceutical batch processing.
• Water treatment facility valve and pump control.
• Power generation plant monitoring systems.

Technical Specifications

Installation Guidelines

• Ensure the system power is disconnected before installing or removing any modules from the baseplate.
• The power supply module must be installed in the leftmost slot of the baseplate.
• Slot 1 is reserved for the CPU module or compatible option modules.
• When connecting expansion or remote baseplates, ensure the total cable length adheres to system specifications (up to 700 feet for remote baseplates).
• Maintain proper ventilation around the baseplate to prevent overheating; avoid mounting near high-EMI sources.
• Use shielded cables for expansion connections to maintain signal integrity.

FAQ

What is the primary function of the IC693CHS391?

The IC693CHS391 acts as the CPU baseplate (Rack 0) for a GE Series 90-30 PLC system, providing the physical mounting and electrical backplane for the CPU, power supply, and I/O modules.

Can this baseplate be used as an expansion rack?

While it is designed as a CPU baseplate, it serves as the foundation for the main rack. Expansion and remote baseplates are used to add additional I/O capacity to the system.

What is the maximum number of additional baseplates supported?

The number of supported expansion baseplates depends on the specific CPU model installed. For example, the CPU 350 supports up to seven additional baseplates, while other models may support up to four.
