GE IC697CHS783 Series 90-70 VME Integrator Chassis

Product Overview

The IC697CHS783 is a high-capacity 17-Slot VME Integrator Rack belonging to the GE Fanuc Series 90-70 and PACSystems RX7i controller families. Built with a highly flexible VME standard C.1 compliant backplane, this chassis permits seamless co-processing by hosting both standard GE modules and 3rd-party VME-based boards. It serves as the ultimate structural and communications foundation for advanced, high-speed industrial data processing and large-scale plant automation setups.

Core Features

• 17-Slot VME Backplane: Supports open-architecture VME standard C.1 for mixing 3rd-party and proprietary modules.
• Dual Mounting Profiles: Reversible engineering adapts to standard 19-inch front racks or 10-inch deep rear panels.
• Integrated Latches: Robust molded alignment latches hold plug-in cards firmly against heavy machinery vibration.
• Configurable Rack ID: Onboard physical jumpers (JP1–JP4) allow rapid hardware address tuning across multi-rack networks.

Technical Specifications

Engineering & Installation Guide

• Rack ID Configuration: Set physical hardware jumpers JP1 to JP4 to define the rack ID before mounting the unit. Misconfigured jumpers cause immediate I/O addressing bus conflicts with the CPU.
• Mechanical Load Management: Given the substantial 8.2 kg empty base weight, ensure your standard 19-inch rack rails or enclosure sub-panels are fully anchored to sustain the total weight load once all 17 slots are populated with heavy boards.
• Thermal Optimizations: For ambient operations trending near the +60°C maximum limit, or when using power-hungry 3rd-party VME computing cards, always fit the optional IC697ACC721 ball-bearing fan tray to prevent hot-spot stagnation.

Technical FAQs

Q1: What does VME Standard C.1 compliance mean for this integrator rack?
A1: It indicates an open-architecture backplane interface. Instead of restricting you to standard GE Fanuc modules, it allows engineers to integrate specialized 3rd-party VME-bus cards (like custom network links or high-speed processing modules) directly into the same hardware loop.

Q2: Can the IC697CHS783 chassis operate from separate power supplies for the 5V and 12V rails?
A2: No. The internal backplane power distribution network is strictly optimized for a unified, single power source supply configuration that manages both the 3.3A @ 5VDC and 1.1A @ 12VDC loads simultaneously to maintain system synchronization.

Q3: How do the molded latches prevent hardware failures in high-vibration plants?
A3: Microphonic vibration can cause slotted cards to walk out of their backplane seating over time, inducing tracking data faults. The factory-molded mechanical latches lock each module faceplate into the rigid frame, guaranteeing consistent, vibration-proof electrical contact.
