IC695LRE001 GE Fanuc PACSystems RX3i Serial Bus Transmitter

Product Overview

The GE Intelligent Platforms / GE Fanuc IC695LRE001 is a high-speed serial bus transmitter module. It bridges the main PACSystems RX3i universal backplane with remote expansion racks. The unit translates backplane logic signals into differential serial signals. It enables seamless data flow across distributed automation chassis over long distances.

System Compatibility and Architecture

The module plugs into the rightmost expansion slot on the RX3i universal backplane. It links serial expansion backplanes directly to the main system CPU. The hardware supports legacy GE Series 90-30 serial expansion racks. System logic handles I/O scanning transparently without custom protocol code.

Installation and Mounting Guidelines

Always disconnect main power before mounting the module into the chassis slot. Insert the IC695LRE001 into the designated expansion connector on the universal rack. Tighten panel retention screws securely to establish proper electrical grounding. Attach the shielded expansion cable to the front-facing multi-pin port.

Diagnostic Capabilities and LED Status

Two diagnostic LEDs provide real-time operational feedback for system technicians. The Expansion OK LED turns solid green when 5V backplane power is active. The Expansion Active LED illuminates during active data exchange across the bus. If communication breaks down, the Active LED turns off immediately to indicate fault conditions.

Suitable Equipment and Application Scenarios

• Large-scale water treatment plants requiring distributed I/O racks across separate control rooms.
• Automotive stamping lines linking remote valve manifolds to the main RX3i processor.
• Material handling systems spanning up to 700 feet across warehouse facilities.
• Power generation skids requiring centralized monitoring of distant field instrumentation chassis.

Global PLC Spare HUB's Insight

During a plant upgrade, a customer experienced periodic communication loss on a 400-foot expansion drop. The customer originally suspected a faulty IC695LRE001 module. Field diagnostics revealed missing cable shielding ground connections near high-voltage motor drives. Properly grounding the shield drained industrial noise and restored stable 500 kbps communication. Always route long expansion cables away from high-voltage AC wiring to prevent EMI interference.

Selection and Purchasing Guide

Choose the IC695LRE001 when expanding local or remote I/O chassis via serial connections. Calculate total cable distance before selection to stay within the 700-foot maximum limit. Verify that your universal backplane contains an open right-side expansion connector slot.

Frequently Asked Questions (FAQ)

Q: Where do I install the IC695LRE001 transmitter module in the rack?

A: Install it specifically into the custom expansion connector slot on the right side of the universal backplane.

Q: What cable distance does the IC695LRE001 support for remote chassis links?

A: It supports up to 50 feet for local expansion cables and 700 feet for remote expansion cables.

Q: What causes the Expansion Active LED to turn off during machine operation?

A: The LED turns off when data communication fails between the main rack and remote expansion chassis.

Q: Does the IC695LRE001 module require external 24 VDC auxiliary power?

A: No, it draws 132 mA directly from the 5 VDC backplane supply.

Q: How do field technicians prevent signal dropouts on long remote cable runs?

A: Ensure proper cable shield termination and maintain separation from high-voltage power lines.
