GE Fanuc IC697BEM735 Series 90-70 Remote I/O Scanner Module

Product Overview: GE Fanuc IC697BEM735 Remote I/O Scanner

The GE Fanuc IC697BEM735 is a high-performance remote I/O scanner module engineered for GE Series 90-70 PLC architectures.

This module creates a reliable communication link between remote I/O racks and the primary IC66 Bus network.

Engineers use the IC697BEM735 to consolidate field signals and expand controller range across vast industrial facilities.

The single-slot module seamlessly integrates standard IC697 discrete and analog hardware, PCMs, and bus transmitters.

A transparent hinged faceplate shields the inner circuitry while providing visual visibility for diagnostic LEDs.

The module communicates over long distances up to 7,500 feet (2,275 meters) without signal loss.

Each scanner drop supports up to 1,024 discrete I/O points or 64 analog channels efficiently.

Technical Specifications

System Compatibility

• Supports host communication with GE Series 90-70 IC697 CPUs.
• Interfaces directly with IC660 and IC655 PLC systems.
• Connects to personal computers equipped with PCIM interfaces or QBIM communication cards.
• Integrates third-party GENI-based interface units on the IC66 Bus network.
• Allows co-existence with companion scanners like the IC697BEM733 on shared multi-drop networks.

Installation Guide

• Turn off power to the destination IC697 rack before inserting the module.
• Align the IC697BEM735 circuit board with the rack guide rails carefully.
• Slide the module inward until rear backplane connectors firmly seat into position.
• Tighten the top and bottom rack retaining screws to secure mechanical grounding.
• Connect the IC66 Bus serial lines to the rear 16-point terminal assembly.
• Maintain twisted-shielded cable wiring to protect signal paths against electromagnetic interference.

Commissioning, Diagnostics, and Maintenance

• Configure the module using MS-DOS programming tools or an IC66 Genius handheld monitor.
• Monitor the 3 front panel LEDs to assess operational status during startup.
• The LEDs display power state, active bus communication, and internal hardware health.
• Use the 9-pin front D-type port to attach diagnostic tools quickly on the plant floor.
• Isolate module issues by reviewing LED error codes before removing field wiring.

Compliance and Certification

• UL Listed for industrial control equipment applications.
• CE Compliant for European electromagnetic compatibility standards.
• Class I, Division 2 Hazardous Location rated for industrial field safety.

Typical Application Scenarios

• Distributed Plant Architecture: Connecting remote I/O sub-racks across large water treatment facilities.
• Long-Distance Process Monitoring: Linking localized sensor racks in oil refineries up to 7,500 feet away.
• System Upgrades: Integrating legacy IC66 field nodes into centralized Series 90-70 control systems.

Global PLC Spare HUB's Insight

Our engineering team frequently evaluates field returns and system retrofits involving the GE Fanuc IC697BEM735. During a recent field audit at a paper processing facility, intermittent dropouts occurred across a 1,500-foot IC66 Bus run. Technicians initially suspected a failed scanner card. However, diagnostic testing via the 9-pin handheld connector revealed cumulative signal degradation caused by improper shield grounding on terminal 12. Once we corrected the bus cable shield routing, the IC697BEM735 restored 100% data throughput without dropping packets. We recommend verifying line termination resistance (75 ohms) at both ends of long bus segments during installation to ensure long-term stability.

Selection Guide & Buying Advice

When selecting a remote I/O scanner for GE Series 90-70 systems, confirm your network media type and I/O density.

The IC697BEM735 is ideal for environments using IC66 Bus architectures requiring up to 1,024 discrete points.

If your system uses alternate bus protocols or higher density backplanes, double-check CPU firmware compatibility prior to purchase.

Frequently Asked Questions (FAQ)

Question: How do I set the bus address for the IC697BEM735 scanner?

Answer: You must configure the bus address software-side using MS-DOS configuration software or an IC66 Genius Handheld Monitor connected via the front port.

Question: Can I hot-swap the IC697BEM735 module while the rack is powered?

Answer: No, always turn off system backplane power to the IC697 rack before inserting or removing the scanner to prevent circuit damage.

Question: What is the maximum number of remote drops supported on a single IC66 Bus line?

Answer: A single IC66 Bus line supports up to 30 remote drops, with each drop containing single or multiple rack configurations.

Question: What should I check if the diagnostic LEDs indicate a communication fault upon startup?

Answer: Verify cable polarity on the rear 16-point terminal block, inspect terminal resistor placement, and confirm correct baud rate matching in software settings.
