Product Introduction
ABB PM825 3BSE010796R1 is a compact S800 processor unit for the AC800M control platform. It runs cyclic control logic, analog loops and sequential programs while communicating with S800 I/O via ModuleBus.
The backup lithium battery preserves application RAM data during power outages. This DIN rail controller fits smaller control cabinets and is widely used as a drop-in replacement for legacy PM825 hardware in existing 800xA installations.

Application Scenarios & Field Experience
Part 1 (Narrative Paragraph)
Smaller process skids and auxiliary plant systems often use older PM825 controllers. Battery depletion or component aging triggers random controller resets. Full rack replacement is expensive and time-consuming. The PM825 maintains the original S800 I/O backplane, so technicians replace only the processor without rewiring field instruments.
Part 2 (Numbered List)
- Chemical skids: Batch dosing and small reactor auxiliary control
- Power plants: Balance-of-plant auxiliary pumps and valve sequencing
- Water & wastewater: Pump station control, level and flow regulation
- Food & beverage: Continuous blending and CIP sequence automation
Part 3 (Short Field Story)
A wastewater pumping station’s PM825 controller suffered a dead backup battery. Random cold restarts would drop pump interlocks. The maintenance team installed a new 3BSE010796R1, downloaded the existing Compact Control Builder project, and replaced the battery. The controller held all process setpoints, and pump trips stopped after commissioning. No field wiring changes were needed.
Standard Operating Procedure (SOP) for Quality Control
- Visual & Origin Inspection: Verify ABB OEM marking, serial number, PCB condition, terminal connectors and factory seals for new original inventory.
- Live Rig Testing: Mount on DIN rail with S800 I/O base, apply rated supply voltage, run power-on self-test, validate ModuleBus handshake and battery status reading.
- Firmware Verification: Read and record hardware and firmware revision. Confirm compatibility with target Compact Control Builder version.
- ESD-Safe Packaging: Protect connectors, place inside anti-static bag, seal and pack in rigid shock-resistant carton for shipment.
Frequently Asked Questions (FAQ)
Q1: Can replace other AC800M CPUs like PM851? A: Not a direct swap. uses ModuleBus I/O architecture. PM851 uses different backplane and memory mapping. Re-validate project compilation and I/O mapping before commissioning.
Q2: What warranty do you provide for this unit? A: We offer a 12-month warranty. Warranty covers hardware defects under rated operating conditions. Overvoltage, ESD damage, or improper battery installation void coverage.
Q3: What is the current stock and shipping timeline? A: We hold limited new surplus inventory. Units ship within 3 business days after order confirmation. Larger project quantities require lead time; confirm stock before locking project schedules.
Q4: Does the ship with preloaded application logic? A: No. The processor ships blank. The control project must be downloaded via Compact Control Builder during commissioning. Check battery condition before loading your program.
Q5: Can I remove or insert this processor while the rack stays powered? A: is not hot-swappable. Cut cabinet power and wait for power supply discharge before removing or installing the unit. Live removal can corrupt ModuleBus and trigger field trips.
