Description
The ABB PM856K01 3BSE018104R1 is a high-performance processor unit kit designed for the AC 800M control system architecture. This central controller integrates an MPC860 microprocessor operating at 48 MHz to manage real-time application logic and process data across industrial control loops. The unit features 8 MB of SDRAM and 2 MB of flash PROM for firmware storage, with dedicated internal battery backup to safeguard volatile memory. Designed for flexible connectivity, the PM856K01 includes dual Ethernet ports for network communication, alongside dual serial interfaces configured for service tool interaction and modem support. It supports modular expansion through the electrical ModuleBus, accommodating up to 12 S800 I/O units, or via an optical ModuleBus for expanded cluster configurations.
Distributed process control in large-scale industrial manufacturing environments.
High-availability automation tasks requiring redundant communication pathways.
Modular expansion of I/O control clusters in process automation plants.

Installation Guidelines
Mounting: Ensure the unit is installed on a standard DIN-rail using the integrated slide-and-lock mechanism.
Grounding: Verify that the power supply ground (L-) and chassis ground comply with electrical safety standards to prevent EMI interference.
Battery Maintenance: The internal low-rate lithium battery (3.6V, 950 mAh) provides a minimum of 48 hours of backup. Ensure batteries are replaced according to site safety protocols.
Cable Routing: Maintain appropriate clearance for Ethernet and serial RJ45 cabling to avoid signal degradation.
Compliance and Certifications
EMC Directive 89/336/EEC
