PM864AK01 REF3BSE018161R1 ABB Processor Unit
Technical Information
PM864AK01 Classic
System 800xA hardware selector
96MHz and 32MB. Package includes: -PM864A, CPU-TP830, Backboard – TB850, Cex-Bus Terminator – TB807, ModuleBus Terminator – TB852, RCU-Link Terminator – Memory Backup Battery (4943013-6)- Does not contain license includes the following text: Note! This part does not comply with RoHS 2 2011/65/EU. These are spare parts for systems placed on the market before July 22, 2017, and can only be ordered for repair, reuse, feature updates or capacity upgrades. For new installations, order PM866AK01 instead.
The CPU board contains the microprocessor and RAM memory, real-time clock, LED indicator, INITpush button, and CompactFlash interface.
The PM864A controller has two RJ45 Ethernet ports (CN1 and CN2) and two RJ45 serial ports (COM3 and COM4) on the baseboard for connecting to the control network. One of the serial ports (COM3) is an RS232C port with a modem control signal, while the other port (COM4) is isolated and used to connect to configuration tools. The controller supports CPU redundancy for higher availability (CPU, cex bus, communication interface, and S800 I/O).
Simple DIN rail connection/separation procedure with unique sliding and locking mechanisms. All baseboards have a unique Ethernet address, which provides a hardware identity for each cpu. This address can be found on the Ethernet address label on the TP830 baseboard.
