ABB PM825 | 3BSE010796R1 | AC80 Processor Module

The ABB PM825 3BSE010796R1 is an AC80 processor module and is cataloged by ABB as “PM825; PM825 S800 Processor.” It belongs to ABB’s legacy AC80 / Advant Master control architecture and is used as the central processor for compatible industrial control systems.

ABB’s current product record shows that 3BSE010796R1 is no longer for sale and identifies 42000052 as the replacement product ID. The original PM825 is supplied without system software, so application software/configuration must be considered separately when replacing a unit.

Functional Description

The PM825 acts as the processing unit of an AC80 control system. It executes the installed control application and manages communication with associated system components.

One important point when buying a replacement: the ABB documentation explicitly states “no System Software Program including.” In other words, replacing the physical processor does not automatically mean the application configuration is present. The software/application backup and system configuration need to be handled separately.

Typical Applications

ABB Advant Master systems
AC80 industrial controllers
Industrial drive control
Process automation
AF100-based control networks
Power-generation equipment
Factory automation
Legacy ABB control-system maintenance

Installation & Configuration

Verify PM825 / 3BSE010796R1 on the existing unit.
Check whether the replacement is the same hardware revision.
Back up the existing application and configuration before replacement.
Record AF100 and power connections.
Remove the existing processor using appropriate ESD precautions.
Install the replacement processor in the correct AC80 position.
Connect the power and AF100 interfaces.
Install/verify the required backup battery where applicable.
Restore the approved system software and application configuration.
Power up and check processor/system diagnostics.
Verify communication with the associated control system.
Perform controlled functional testing.

⚠️ Replacement Note

There is a lot of inaccurate PM825 information on third-party websites, including specifications for newer or unrelated controller generations. For this particular 3BSE010796R1, ABB’s own product data is the better reference: it identifies the unit as an AC80 Processor / PM825 S800 Processor, with 42000052 as the replacement product ID.

Also, don’t confuse this legacy PM825 with later ABB AC 800M processor modules that happen to use similar PM8xx naming.
