ABB PM851 3BSE018169R1 Power Supply Module – AC800M Series
Imagine a critical production line — a paper mill, a chemical reactor, or an offshore platform — suddenly losing its controller power. Within seconds, the entire automation system goes dark: PLCs stop scanning, I/O modules lose communication, and operators are left blind. The ABB PM851 (3BSE018169R1) is the power supply and processor module that prevents exactly this scenario. It is not a peripheral accessory; it is the beating heart of the AC800M controller cabinet, delivering regulated power and real-time processing to every connected module in the rack.
Within ABB’s AC800M family — one of the most widely deployed DCS platforms in process industries worldwide — the PM851 occupies the role of the primary CPU and power supply unit. Its dual function (processing + power distribution) reduces cabinet footprint and simplifies wiring, making it the preferred choice for brownfield upgrades and greenfield projects alike. From pulp & paper plants in Scandinavia to LNG terminals in the Middle East, the PM851 has accumulated millions of operating hours as a proven backbone of ABB System 800xA installations.

Frequently Asked Questions
Q: Is the PM851 the same as 3BSE018169R1?
A: Yes. PM851 is the commercial model name; 3BSE018169R1 is ABB’s internal ordering reference number. Both refer to the identical hardware unit.
Q: Can the PM851 be used as a drop-in replacement for an existing AC800M controller?
A: In most cases, yes — provided the firmware version is compatible with your existing project. We recommend verifying the Control Builder M version before installation.
Q: Do you provide a warranty?
A: Yes. New units carry the manufacturer warranty. Refurbished and tested-used units carry a 90-day Konmask.com functional warranty.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Absolutely. We handle bulk orders and long-term supply agreements. Contact us for volume pricing.
Q: What is the typical lead time for an out-of-stock PM851?
A: Typically 2–4 weeks for sourced units. We maintain a global supplier network to minimize delays.
