ABB 3BSE081637R1 PM866AK02 is a redundant central processing unit package designed for the AC 800M control system within the ABB Ability System 800xA platform. The unit houses a microprocessor, RAM, real-time clock, LED status indicators, INIT push button, and a CompactFlash interface. It provides CPU hardware redundancy with a maximum switchover time of 10 ms for high availability application environments. Network connectivity includes two built-in RJ45 Ethernet ports for Control Network communication using MMS and IAC protocols, alongside RS-232C serial ports for configuration and general communication. The controller interface extends to Modulebus and CEX-Bus communication lines, managing up to 32 applications and supporting up to 84 Modulebus I/O modules in a redundant processor setup.
