GE IC660BBR100 Block Relay Output – Obsolete Series 90 Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Solving the Discontinued Hardware Crisis

The GE Series 90 platform — including the Genius I/O bus architecture that the IC660BBR100 operates within — was the backbone of discrete and process manufacturing automation throughout the 1990s and 2000s. Tens of thousands of these systems remain in active service across automotive, food and beverage, chemical, and utilities sectors. GE Fanuc's acquisition by Emerson Automation Solutions and subsequent product rationalization removed the IC660BBR100 from active production. The OEM will not manufacture replacements.

The IC660BBR100 is not a generic relay block. It communicates over the Genius Bus protocol, which is proprietary to the GE Series 90 architecture. There is no cross-compatible substitute from another manufacturer that can be installed without a full system redesign. For any facility running a Genius Bus network, this module is a single point of failure with no off-the-shelf modern equivalent.

Condition & Reliability Assurance

Every IC660BBR100 unit processed by DriveKNMS undergoes a structured 5-step quality protocol before dispatch review:

• Step 1 – Visual and Mechanical Inspection: Full enclosure inspection for cracks, burn marks, and connector pin integrity. Relay contact pins are examined under magnification for corrosion and deformation.
• Step 2 – Electrolytic Capacitor Assessment: Capacitors are tested for ESR (Equivalent Series Resistance) drift and capacitance loss — the primary failure mode in boards stored beyond 10 years.
• Step 3 – Firmware Version Verification: Where accessible, firmware revision is confirmed against known compatible versions for Series 90-30 and 90-70 host controllers.
• Step 4 – Pin and Connector Corrosion Remediation: All I/O terminal blocks and bus connectors are cleaned and treated. Corroded pins are flagged and units are downgraded or rejected accordingly.
• Step 5 – Functional Output Test: Relay coil actuation and contact switching are verified under load conditions prior to packaging.

Units are classified as New (factory-sealed), Refurbished (tested and restored to operational specification), or As-Is (sold for parts only, clearly labeled). Condition is disclosed in full at the time of quotation.

Key Features for System Maintenance

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.
