ABB 3BSE018161R1 PM64AK01 AC 800M Processor Unit

ABB AC 800M Processor Unit PM864AK01 (3BSE018161R1) is the central processing unit for ABB's AC 800M controller family, serving as the computing core of the automation system. The module houses the PM864A main processor and is designed for demanding industrial environments, with a compact footprint of 135 mm (depth) × 186 mm (length) × 119 mm (width) and a net weight of about 1.2 kg. It supports voltages up to 1000 V and uses a lithium‑ion backup battery (model 4943013-6-4, approximately 9 g) to preserve memory during power interruptions, while clock synchronization between AC 800M controllers is specified at 1 ms via CNCP protocol for coordinated multi‑controller operation. When deployed as part of an AC 800M control solution, PM864AK01 provides high‑performance processing to handle complex automation tasks across industrial environments.
