ABB BAS-DC2 Circuit Board – Obsolete Bailey Series Spare Part

DriveKNMS maintains a controlled inventory of hard-to-find ABB legacy modules sourced through verified industrial channels. Each unit passes a structured inspection protocol before dispatch.

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 ABB Bailey INFI 90 and Network 90 platforms were installed across thousands of power generation, chemical, and pulp & paper facilities from the 1980s through the early 2000s. Many of these systems remain in active service today — not because operators are unaware of their age, but because the cost and risk of replacement outweigh the cost of maintenance. The BAS-DC2 circuit board sits within the control backbone of these systems. It is not a peripheral accessory. Its failure can halt a process loop, trigger a plant-wide alarm cascade, or force an unplanned shutdown.

ABB's official support for the Bailey INFI 90 hardware line has been progressively wound down. Spare parts are no longer available through standard distribution channels. Facilities that did not build strategic inventory reserves during the transition window now face a secondary market that is both thin and unverified. A single unvetted counterfeit or degraded board installed in a live control system represents a safety and liability exposure that no plant manager should accept.

Condition & Reliability Assurance

Every BAS-DC2 unit dispatched by DriveKNMS passes a five-stage inspection process designed specifically for legacy industrial electronics:

Key Features for System Maintenance

• Drop-in Replacement: The BAS-DC2 is a direct slot-for-slot replacement within compatible Bailey backplane configurations. No hardware modification to the chassis is required.
• No Reprogramming Required: Configuration data resides in the DCS database, not on the module itself. Swapping a verified BAS-DC2 does not require re-engineering the control strategy or reloading application logic from scratch in standard replacement scenarios.
• Avoids Engineering Reconstruction Costs: Maintaining the existing hardware platform eliminates the need for I/O mapping redesign, loop tuning from baseline, and third-party system integration work that accompanies a platform migration.
• Preserves Operator Familiarity: Operators trained on Bailey HMI environments continue working without retraining overhead. Institutional process knowledge is retained.
• Extends Asset Life 5–10 Years: A verified spare inventory strategy, combined with proactive preventive maintenance, is the lowest-cost mechanism available to defer a multi-million dollar DCS replacement project.

Q: What if my system requires a specific hardware revision of the BAS-DC2?
A: Revision information is documented during our inspection process. Inform us of your required revision at the time of inquiry and we will confirm compatibility before confirming the order.

Q: Can export requirements be reviewed?
A: Destination, documentation and routing requirements are confirmed during RFQ review.
