GE Fanuc IC697CHS750 Series 90-70 Rear Mount Expansion Rack

Product Overview

The IC697CHS750 is a heavy-duty Rear Mount Rack chassis from the GE Fanuc Series 90-70 PLC range. This rugged metal rack provides the physical foundation, high-speed backplane communication lanes, and structural alignments needed to host Series 90-70 CPUs, I/O modules, and coprocessors. Engineered for high-density, back-panel industrial layouts, it optimizes enclosure space while delivering stable structural integrity under severe shop-floor conditions.

Core Features

• Multi-Slot Expansion: Houses multiple Series 90-70 plug-in modules to support flexible, large-scale system expansion architectures.
• Dual Rack Operations: Advanced backplane distribution enables dual rack execution from a single, shared power supply interface.
• Universal Power Link: Fully compatible with both AC and DC modular plug-in power supplies without requiring extra hardware.
• Passive Convective Cooling: Thermally engineered chassis design eliminates the need for failure-prone cooling fan assemblies.

Technical Specifications

Engineering & Installation Guide

• Enclosure Fit Profile: Ensure your electrical panel meets the minimum 10-inch enclosure mounting depth specification to accommodate the rack, modules, and faceplate cable bend radii securely.
• Module Alignment & Seating: Given the solid 3.6 kg metal chassis weight, verify back-panel structural plates are thick enough to eliminate bowing. Guide card slots carefully during module insertions to protect delicate backplane pins.
• Dual Rack Power Layouts: When linking two racks to a single power supply source, carefully calculate the total 5 VDC bus current consumption across all populated slots to prevent under-voltage dropouts.

Technical FAQs

Q1: Does the IC697CHS750 rear mount chassis require dedicated external fans or active cooling units?
A1: No. The chassis is engineered for natural thermal convection, performing reliably across its full 0°C to 70°C ambient range without mechanical fan assemblies. Ensure surrounding air paths within the cabinet remain unblocked.

Q2: Can I combine both AC and DC input power supplies inside the same IC697CHS750 backplane?
A2: The rack architecture is fully compatible with both plug-in AC and DC power modules. However, do not mix different power supplies on a single bus structure unless explicitly following a verified, redundant parallel configuration blueprint.

Q3: Why is the 5 VDC voltage rating parameter critical for this Series 90-70 rack?
A3: The 5 VDC specification defines the main logic bus voltage provided by the plug-in power supply module to fuel the microprocessors and internal transceiver chips of all slotted I/O cards. Stable, ripple-free 5 VDC delivery is essential for accurate system backplane communications.
