New Arrival ABB PM866AK02 Redundant Processor Unit , 3BSE081637R1

News January 12, 2023


The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a CompactFlash interface.

The base plate of the PM866 / PM866A controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with modem control signals, whereas the other port (COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).

Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base plates are provided with a unique Ethernet address which provides every CPU with a hardware identity. The address can be found on the Ethernet address label attached to the TP830 base plate.

Package including:

2 pcs PM866A, CPU

2 pcs TP830, Baseplate, width =115mm

2 pcs TB807, ModuleBus terminator

1 pcs TK850, CEX-bus expansion cable

1 pcs TK851, RCU-Link cable

2 pcs Battery for memory backup (4943013-6) 1 for each CPU
