Emerson MOX12-P3509B 80026-173-23 Power Supply Module – Ovation Distributed Control System
When a power supply module fails inside an Ovation DCS cabinet, the consequences cascade instantly — controllers lose regulated voltage, I/O racks go offline, and the entire process loop becomes blind. In power generation, refining, or water treatment, even minutes of unplanned downtime translate into significant production loss and safety risk. The Emerson MOX12-P3509B (Part No. 80026-173-23 / 80026-173-23-R) is the factory-specified replacement that restores system integrity without re-engineering your power architecture.
Within the Ovation DCS platform — Emerson’s flagship distributed control system trusted by over 10,000 installations worldwide — the MOX12-P3509B occupies a critical tier as the primary DC power conversion and distribution module. Its dual part-number designation (80026-173-23 and the revised 80026-173-23-R) reflects Emerson’s continuous hardware refinement while maintaining full backward compatibility with existing Ovation controller and I/O chassis.

Frequently Asked Questions
Q: What is the difference between 80026-173-23 and 80026-173-23-R?
A: The “-R” suffix denotes a revised hardware revision of the same MOX12-P3509B module. Both revisions are functionally equivalent and backward compatible within Ovation DCS systems. We will confirm which revision is available and appropriate for your installation.
Q: Is this module new or refurbished?
A: We stock both new surplus (unused, original packaging) and tested refurbished units. Please specify your preference when submitting your inquiry, and we will advise on current availability and pricing accordingly.
Q: Can this module be used as a hot-swap replacement without shutting down the DCS?
A: In Ovation systems configured with redundant power supply architecture, hot-swap replacement is supported. We recommend consulting your Ovation system documentation or contacting our technical team to confirm your specific cabinet’s redundancy configuration before proceeding.
Q: What warranty do you offer?
A: All modules are covered by Konmask.com’s standard warranty. Please contact us for specific warranty terms applicable to your order condition (new surplus vs. refurbished).
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoices, packing lists, and certificates of origin as required. We work with established freight forwarders experienced in industrial equipment export compliance.
