GE IC695CHS007 Universal Backplane for PACSystem RX3i

Technical Specifications Breakdown

Key parameters for the IC695CHS007 are listed below for quick reference:

Industry Applications

• Remote I/O Architectures: The backplane's compact size and support for serial-based modules make it suitable for distributed control systems where space is limited.
• Machine Control Upgrades: Replace aging Series 90-30 racks with the IC695CHS007 while retaining existing I/O modules, minimizing downtime and retraining.
• Process Automation: Integrate analog and discrete I/O modules from the RX3i family for precise monitoring and control in chemical, oil and gas, or water treatment plants.

Installation & Setup Guidance

Mount the backplane horizontally on a panel using the provided holes. Ensure a minimum clearance of 102 mm (4 inches) on all sides for proper airflow. Use 14 to 22 AWG wire for the isolated 24 VDC terminal strip (TB1): terminal 7 for +24 VDC and terminal 8 for isolated ground. The internal grounding bar simplifies shield connection for hosted modules. Always install in a NEMA/UL Type 1 (IP20) enclosure; for hazardous locations, use an IP54 or greater enclosure.

Maintenance & Reliability

Periodically inspect the backplane for dust accumulation and ensure all module connections are secure. The module supports hot-swap, allowing replacement of I/O modules without powering down the rack, which minimizes production interruptions. Verify that the enclosure maintains the required IP rating to protect against moisture and contaminants.

Universal Backplane for Seamless Integration

The GE IC695CHS007 universal backplane is a core component of the PACSystem RX3i platform, designed to host power supplies and I/O modules in a compact 7-slot form factor.

Optimized Slot Architecture for Mixed I/O

Slot 0 is reserved for an IC695 power supply, while slots 1 through 5 feature dual connectors (PCI and serial) to accommodate both RX3i and Series 90-30 modules. Slot 6 supports only PCI-based RX3i modules, ensuring high-speed data transfer for demanding applications. This design allows engineers to reuse existing IC693 and IC694 modules, reducing upgrade costs.

Compatibility & Integration

The IC695CHS007 is compatible with the entire PACSystem RX3i and Series 90-30 module families, including IC695, IC694, and IC693 series. It supports both PCI and serial bus communication, enabling seamless integration with existing control networks. The backplane is available in two releases: the initial IC695CHS007-AA and the enhanced IC695CHS007-BA with improved PCI connector mechanics.

Selection Guide & Purchasing Advice

When selecting a backplane, consider the number of I/O points required and the mix of module types. For larger configurations, consider 10- or 18-slot backplanes from the same series. AutoDCSTech stocks this model and can advise on lifecycle status and availability.

Troubleshooting & Common Issues

If modules are not recognized, verify that they are fully seated in the correct slot type (PCI-only modules in slot 6, serial modules in slots 1-5). Check the 24 VDC supply at TB1 and ensure the grounding bar is connected to earth ground. For intermittent faults, inspect the enclosure for overheating and confirm that clearance requirements are met.
