ABB PM864AK02 3BSE018164R1 is a redundant AC 800M processor package for System 800xA control applications. The package contains two PM864AK01 processor units together with the TK850 CEX-bus expansion cable and TK851 RCU-Link cable required for the documented redundant arrangement.
Each PM864A processor uses a 96 MHz MPC862 CPU with 32 MB RAM and 23.522 MB of application memory. ABB specifies redundancy support with a maximum switch time of 10 ms, up to 32 applications, 64 programs per application and 32 tasks.
For replacement, verify the full PM864AK02 3BSE018164R1 package identity, firmware and Control Builder compatibility, redundant pair status, RCU-Link and CEX-bus cabling, supply range and application backup before commissioning.
