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.

Features

  • Integrated MPC860 microprocessor architecture.
  • 8 MB SDRAM and 2 MB Flash PROM memory capacity.
  • Dual 10Base-T Ethernet communication ports (CN1, CN2) supporting IEEE 802.3 standards.
  • Two dedicated serial ports: COM3 (RS-232C with modem support) and COM4 (RS-232C for service tools).
  • Electrical ModuleBus interface for local connection of up to 12 S800 I/O units.
  • Internal 5ms power reservoir for controlled system shutdown during input voltage loss.
  • Compact slide-and-lock DIN-rail mounting mechanism.

Applications

  • 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.
