Product Introduction
The ABB PM856AK01 is a high-performance central processing unit package engineered for the widely deployed ABB AC 800M distributed control system (DCS) family. As part of the Processor Unit (PU) bundle, it includes the PM856 processor module along with its matching TP850 baseplate and battery backup components.
Featuring an embedded Motorola PowerPC processor architecture, the PM856 provides exceptional execution speed, large memory capacity for user applications, and robust system availability. It supports comprehensive redundancy configurations (CPU and communication redundancy), making it an ideal core controller for complex process control applications in power generation, oil and gas, and heavy manufacturing.

Compliance & Standards Alignment
- Designed and manufactured in compliance with international CE, UL, and RoHS safety and environmental standards.
- Equipped with ruggedized conformal coating to resist corrosive gases, humidity, and chemical pollutants typical of heavy industrial environments.
Technical Note: The “AK01” suffix indicates a complete starter kit package containing the baseplate and battery. When configuring redundant controller nodes, verify that both PM856 modules match identical firmware revision levels to prevent synchronization faults on the control network.
Storage & Asset Preservation Guidelines
- Store the processor package inside its original antistatic ESD bag to protect delicate CMOS logic circuits and flash memory from electrostatic damage.
- Keep warehouse storage environments temperature-controlled with relative humidity maintained strictly below 60%.
- Avoid mechanical shocks, drops, or placing heavy weights on the module box to prevent bending the DIN-rail latching mechanism or backplane pins.
Physical Installation Prerequisites
- Ensure that all control cabinet power feeds and node backplane supplies are completely de-energized and locked out (LOTO) prior to mounting or servicing.
- Snap the TP850 baseplate firmly onto the standard 35mm DIN rail, then carefully seat the PM856 module onto the baseplate pins, ensuring parallel alignment before tightening retention screws.
- Install the backup battery module (SB821) and connect communication cabling securely before powering up the controller rack.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this ABB CPU module?
A: Industrial process control system computers, programmable controllers, and electronic processing modules typically classify under HS code 8537.10 (Boards, panels, consoles for electric control) or 8538.90. Confirm final parameters with your customs broker.
Q: Does the PM856AK01 bundle include the system battery?
A: Yes. The “AK” designated package bundle typically includes the processor unit, baseplate, and necessary backup battery components (SB821) to ensure volatile RAM data protection during power interruptions.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, software version, and inventory conditions; contact our technical sales desk for a formal, time-sensitive quotation.
