GE IC698CHS017 17-Slot VME64-Compliant Rack Chassis

Description

The IC698CHS017 is the primary 17-Slot VME64-compliant Rack Chassis for the GE Fanuc (Emerson) PACSystems RX7i PLC series. As the largest baseplate in the RX7i family, it provides the high-bandwidth backplane necessary for the most demanding integrated control applications, supporting high-speed CPUs, large memory modules, and extensive I/O or communication sets.

Specifications

• Part Number: IC698CHS017
• Series: PACSystems RX7i
• Slot Capacity: 17 slots total.
• Slot 0: Dedicated for the Power Supply (e.g., IC698PWR624).
• Slot 1: Dedicated for the CPU (e.g., IC698CPE010/020).
• Slots 2–17: Available for I/O, Communication, and specialty VME modules.
• Backplane Type: VME64 (64-bit data path) with support for standard VME and RX7i-specific modules.
• Mounting: Rack-mount (Standard 19-inch RETMA rack) or Wall-mount/Panel-mount.
• Dimensions: 48.3 cm x 31.0 cm x 25.4 cm (19.0" x 12.2" x 10.0").
• Weight: Approximately 8.2 kg (18.1 lbs) empty.

Features

• VME64 Integration: Unlike the RX3i (which uses a PCI-based backplane), the RX7i uses the 64-bit VME standard, allowing users to integrate 3rd-party VME modules (vision systems, motion controllers) directly into the PLC rack.
• High-Speed Data Exchange: The backplane supports "Reflective Memory" and high-speed data transfer between modules, essential for synchronized multi-axis motion or complex turbine control.
• Thermal Management: Designed with open-frame ventilation to facilitate airflow; however, due to the high density of 17 slots, an external fan tray is typically required for vertical cooling.
• Robust Power Distribution: The backplane is engineered to distribute high currents (up to 60A on the +5V rail) with minimal voltage drop across the 17-slot span.
• Keyed Module Guides: Ensures that high-pin-count VME connectors align perfectly before seating, preventing bent pins during maintenance.
