Base Racks GE Fanuc IC695CHS007 PACSystems RX3i

Product Overview

The GE Fanuc IC695CHS007, also cataloged as the IC695CHS007 Base Rack, operates as a dedicated hardware component for physical module housing and backplane signal routing within PACSystems RX3i control networks. It provides the mechanical framework and electrical distribution bus to interface seven single-slot I/O, power supply, or processor modules.

Hardware Specifications

Deterministic Backplane Network Scaling

The hardware utilizes an dual-bus backplane architecture that establishes parallel execution paths for high-velocity internal data transfers. The integrated interface supports both high-speed PCI bus communications for native RX3i modules and serial bus signal layers to accommodate legacy Series 90-30 modules. This layout implements direct firmware flash compatibility checks across the active slots, maintaining strict network velocity profiles and preventing data packet collisions during dense I/O scaling updates.

Frequently Asked Questions

Q: Does this base rack support hot-swap operations for connected modules?

A: Hardware insertion and removal under power (RIUP) is supported on the RX3i PCI bus sub-layers for compatible modules. However, the upstream power supply modules or specific legacy configurations require complete backplane power isolation before physical removal to prevent backplane bus communication errors.

Q: What are the backplane current limits for the internal power rails?

A: The passive backplane distributes 5 VDC, 3.3 VDC, and 24 VDC rails directly from the integrated power supply module slot. Total current draw must not exceed the rated output capacity of the installed power supply module or the maximum current limits enforced by the physical trace geometry of the internal circuit board.

Field Installation Guidelines

• Secure the base rack to a flat, unpainted conductive mounting panel using M4 or #8 screws to ensure a direct chassis-to-ground low-impedance electrical connection.
• Maintain a minimum clearance distance of 100 mm on the top and bottom, and 50 mm on both sides of the enclosure to provide proper thermal convection currents.
• Ensure the physical system ground strap is terminated directly to the dedicated grounding terminal lug located on the right side of the rack frame.
• Verify that all terminal block wiring and industrial network cables are routed through separate mechanical wire ducts away from high-voltage motor control lines to prevent electromagnetic cross-talk.
