ABB PM891K01 is an AC 800M processor unit package built around the PM891 CPU for demanding process control applications. ABB documents a 450 MHz processor, 256 MB RAM and 208.985 MB RAM available for applications. The package includes the PM891 CPU module, TB850 CEX-bus terminator and TB853 RCU Control Link terminator, with no software license included. PM891 supports CPU redundancy, twelve communication modules on the CEX bus and two 10/100 Mbit/s Ethernet channels. System compatibility depends on the installed hardware revision, firmware, engineering software, controller project and redundancy architecture. Stockoems supports verification, packaging and worldwide shipping coordination.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments.
PM891 processes engineered AC 800M control applications.
Two 10/100 Mbit/s channels support Control Network communication.
TB853 supports the documented redundant architecture interface.
