GE Fanuc IC697CHS791 5-Slot Front-Mount Baseplate

Description

The IC697CHS791 is a 5-Slot Front-Mount Baseplate designed for the GE Fanuc Series 90-70 PLC system. This baseplate acts as the physical and electrical foundation for the control system, providing the high-speed VME-based backplane required for communication between the CPU, power supply, and I/O modules. The "Front-Mount" designation refers to its mechanical design, which allows for easy installation into standard 19-inch industrial racks or onto a mounting plate within a control cabinet.

Specifications

• Part Number: IC697CHS791
• Series: Series 90-70 PLC
• Slot Capacity: 5 Slots (Slot 1 is always reserved for the Power Supply).
• Backplane Type: VME64-compliant (high-speed parallel bus).
• Module Compatibility: Supports all Series 90-70 CPUs, Memory, I/O, and Communication modules.
• Mounting: Front-mount (Standard 19" rack compatible).
• Dimensions: 26.4 cm x 48.3 cm x 19.0 cm (10.4" x 19.0" x 7.5").

Features

• Rugged VME Architecture: Utilizes the industry-standard VMEbus, which provides superior data throughput and robust electrical noise immunity compared to standard PLC backplanes.
• Mechanical Rigidity: Constructed from heavy-duty aluminum and steel to withstand high-vibration environments typical of power plants and heavy manufacturing.
• Integrated Grounding: Features a dedicated internal ground plane and external grounding studs to ensure signal integrity and protection against EMI/RFI.
• Keyed Slots: Designed with mechanical guides to ensure modules are aligned correctly before making contact with the backplane pins, preventing pin damage.
• Convection Cooling: The chassis design promotes natural airflow around the modules, though it is often paired with an IC697ACC700 fan tray for high-density configurations.
