- Part Type: AC 800M Processor Unit Kit
- CPU: PM864A, 96 MHz
- Memory: 32 MB
- Lifecycle: Classic
Technical Introduction
The ABB PM864AK01 (3BSE018161R1) is a processor unit kit for the AC 800M controller platform, used within ABB System 800xA control architectures. ABB documentation identifies the package as including the PM864A CPU together with the TP830 baseplate, bus terminators, memory-backup battery, and power plug.
The PM864A CPU provides the central processing function for an AC 800M controller, with CEX-Bus and ModuleBus interfaces for communication and S800 I/O expansion. The controller also provides two Ethernet ports and two serial interfaces; ABB’s product documentation identifies the PM864AK01 as a Classic processor unit with a 96 MHz CPU and 32 MB memory.
Best Suited For
- ABB AC 800M controller maintenance
- System 800xA legacy control-system spares
- CPU replacement and planned obsolescence management

ABB PM864AK01 3BSE018161R1
The 1.2 kg weight and 119 × 186 × 135 mm dimensions apply to the processor-unit assembly with its base and associated components, rather than the CPU board alone. ABB documentation confirms the PM864AK01 package contents and the 96 MHz / 32 MB processor configuration.
Field Engineer’s Tech Notes
- Check the battery before commissioning a stored unit. PM864AK01 includes the 4943013-6 memory-backup battery. For a long-stored spare, inspect the battery condition and replace it when required before relying on retained controller data.
- Do not confuse the kit number with the CPU board number. 3BSE018161R1 identifies the PM864AK01 processor-unit kit, which includes the PM864A CPU and TP830 baseplate plus termination and backup components. A procurement request for only the CPU board is therefore a different requirement.
Adaptive QA & Testing Protocol
QA starts by matching PM864AK01 / 3BSE018161R1 and checking that the supplied kit contains the expected PM864A, TP830, TB850, TB807, TB852, battery, and power plug where the sale is for a complete kit.
Functional testing should use an appropriate AC 800M test environment. The CPU is checked for power-up/self-test behavior, Ethernet communication, service-port operation, controller diagnostics, and communication with the applicable CEX-Bus/ModuleBus hardware. Where redundancy is part of the customer’s configuration, the controller should also be checked with the corresponding redundancy hardware and configuration.
Test reports, inspection photographs, and available test videos can be provided upon request.
Buyer’s FAQ
Q: What is ABB PM864AK01 used for?
A: It is an AC 800M Processor Unit Kit used as the controller CPU assembly within ABB control systems, including System 800xA.
Q: Is PM864AK01 still an active product?
A: ABB documentation identifies 3BSE018161R1 / PM864AK01 as a Classic lifecycle product. This makes verified spare stock relevant for maintaining existing AC 800M installations.
Q: What is included with PM864AK01?
A: The documented kit includes the PM864A CPU, TP830 baseplate, TB850 CEX-Bus terminator, TB807 ModuleBus terminator, TB852 RCU-Link terminator, 4943013-6 memory-backup battery, and 3BSC840088R4 power plug.
Q: Can you supply a tested replacement?
A: New surplus, unused, and refurbished availability can vary. For refurbished unit
