Solving the Discontinued Hardware Crisis

The GE Series 90-70 was one of the most widely deployed large-frame PLC platforms of the 1990s and early 2000s. Thousands of facilities worldwide built their automation infrastructure around its modular rack architecture. GE Fanuc formally discontinued the Series 90-70 product line, ending both new production and OEM support. The IC697BEM713 Bus Expansion Module is a structural component of multi-rack configurations — without it, the physical expansion of the control system collapses, forcing either a partial rack consolidation (which may not be electrically feasible) or a full system replacement.

The practical approach for facilities still operating Series 90-70 systems:

• Audit all IC697BEM713 positions across your rack topology and identify single points of failure.
• Maintain a minimum of one cold-spare per expansion bus segment — more for high-criticality lines.
• Source from verified distributors with documented QA processes, not open-market surplus channels where counterfeit and degraded units circulate.
• Pair spare module procurement with a firmware version audit to ensure compatibility with your existing CPU and I/O configuration.

Condition & Reliability Assurance

Discontinued hardware sourced from secondary markets carries real risk. Electrolytic capacitor degradation, firmware version mismatches, pin corrosion from improper storage, and counterfeit assemblies are documented failure modes in the obsolete parts supply chain. DriveKNMS applies a 5-step QA process to every IC697BEM713 unit before it leaves our facility:

• Step 1 – Visual and Mechanical Inspection: Board-level examination for physical damage, burn marks, cracked solder joints, and connector pin integrity.
• Step 2 – Electrolytic Capacitor Assessment: Targeted inspection of capacitor condition — a primary failure point in modules that have been in storage or light-duty service for extended periods.
• Step 3 – Firmware Version Verification: Confirmation of firmware revision against known compatible versions for the Series 90-70 platform.
• Step 4 – Pin and Backplane Connector Inspection: Corrosion screening on all backplane interface pins, with cleaning where required.
• Step 5 – Functional Verification: Bench-level power-on and communication test where test infrastructure supports the module type.

Key Features for System Maintenance

How do I confirm the unit is genuine and not counterfeit?
All units sourced by DriveKNMS are inspected against known GE Fanuc manufacturing markings, board revision codes, and component layouts. We provide photographic documentation of the specific unit upon request before dispatch review.

Can this module be used with IC697CHS750 and IC697CHS782 racks?
The IC697BEM713 is designed for use within the Series 90-70 rack family. Compatibility with specific rack models should be verified against your system's configuration documentation before installation.

Do you offer long-term spare parts reservation?
Yes. DriveKNMS offers reserved inventory agreements for facilities requiring guaranteed access to critical obsolete components over a defined service period. Contact us to discuss terms.
