IC694CHS398 GE Fanuc Baseplates and Racks PACSystems RX3i

Product Overview

The GE Fanuc IC694CHS398, also cataloged as the IC694CHS398 Expansion Baseplate, operates as a dedicated hardware component for structural chassis optimization and electrical interconnection within PACSystems RX3i platforms. The physical rack provides the local backplane architecture required to map data lines and supply logic voltages across supplementary input/output modules.

Hardware Specifications

Industrial Control & Deterministic Backplane Networks

The local backplane traces enforce structural parameters to protect internal register states and manage backplane bus communication velocity metrics between adjacent expansions. Programmed addressing protocols drive clear logic segmentation, supporting steady execution when balancing physical I/O density scaling profiles across distinct panel zones. This structural base operates beneath the execution software layer, sustaining exact firmware flash compatibility across integrated cards while bridging remote operations over Profinet / EtherNet/IP deterministic networks.

Frequently Asked Questions

Q: What is the maximum allowable distance when linking the IC694CHS398 expansion baseplate to a primary universal baseplate?

A: The physical boundaries of the RX3i serial expansion bus architecture restrict the overall cumulative cable length to a maximum limit of 15 meters (50 feet) when utilizing standard overall shielded expansion cables.

Q: Can an engineering technician install a central processing unit (CPU) module into any general-purpose slot of this baseplate?

A: No. The IC694CHS398 is an expansion-only backplane that handles serial bus communications. It lacks the high-speed PCI Express bus interface traces required to boot or execute processes from an RX3i central processing unit module.

Field Installation Guidelines

• DIN-Rail and Panel Mounting: Snap the chassis rear integrated retention clamps onto a clean 35 mm DIN-rail section, or bolt the backplane frame directly to the enclosure steel subpanel using four M4 pan-head screws.
• Chassis Grounding Sequence: Connect a heavy-gauge, low-impedance copper conductor from the dedicated ground terminal stud on the baseplate chassis directly to the primary enclosure safety ground bar.
• Expansion Cable Retention: Insert the 25-pin D-sub expansion connector plug into the matching port at the baseplate end. Tighten the dual jack screws securely to avoid connection failures caused by mechanical vibration.
• Module Slot Alignment: Disconnect all upstream supply lines before inserting functional cards. Slide each I/O module down the molded chassis slot guides until the backplane multi-pin plug engages fully into the receiver block.
