Product Description
ABB · AC 800M Controllers
ABB PM856AK01 3BSE066490R1 — AC 800M Processor Unit, 24 MHz / 16 MB
PM856AK01 is an AC 800M processor unit based on the PM856A CPU, with 24 MHz clock frequency, 16 MB memory and 0.46 ms performance for 1,000 Boolean operations.
01 / Overview
AC 800M Processor Unit
PM856A CPU with TP830 baseplate and termination hardware.
PM856AK01 is the 3BSE066490R1 processor-unit package for the ABB AC 800M controller family. The package includes the PM856A CPU, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator and memory-backup battery.
The PM856A baseplate provides two RJ45 Ethernet ports, CN1 and CN2, for the Control Network, plus COM3 and COM4 serial ports. COM3 is RS-232C with modem-control signals; COM4 is an isolated configuration-tool port.
