PM858K02
ABB PM858K02 AC 800M Redundant Controller Unit, 33 MHz, 16 MB Memory, with Dual CPU Configuration.
Overview
Description
ABB PM858K02 Redundant Processor Unit for the AC 800M automation system, featuring a 33 MHz MPC866 processor and 16 MB memory. The package includes two PM858 CPU units, two TP830 baseplates, two TB807 ModuleBus terminators, one TK850 CEX-Bus expansion cable, one TK851 RCU-Link cable, and two batteries for memory backup. Each controller provides two RJ45 Ethernet ports for Control Network connectivity and two RJ45 serial ports, including an RS-232C interface with modem control signals and an isolated configuration-tool interface. The unit supports CPU redundancy to improve system availability, along with redundant communication interfaces and S800 I/O configurations. Additional features include a real-time clock, LED indicators, an INIT push button, CompactFlash storage support, and DIN-rail mounting with a slide-and-lock mechanism. The controller supports a 24 V DC power supply and is compatible with ABB System 800xA version 6.0.2 and Compact Control Builder version 6.0.0-1 or later.
