ABB 1SAP150100R0160 - PM591-ARCNET CPU (AC500)

The ABB 1SAP150100R0160 is the order code for the PM591-ARCNET CPU of the AC500 PLC family, listed in ABB conformity documentation as PM591-ARCNET: AC500, CPU, 4MB, 24VDC, ARCNET. Distributor listings confirm the same code as a 4MB ARCNET-equipped CPU module, offered refurbished and new with warranty. The ARCNET variant serves installations built on ARCNET networking rather than Ethernet, making it a like-for-like spare for legacy AC500 cabinets using PM591-class CPUs with 4MB of memory. Confirm firmware revision and network requirements against your installed unit before ordering.
