PRODUCT INFORMATION
Product Overview
The ABB PM866AK02 3BSE081637R1 is an AC800M Controller designed for redundant operation. It features a 133 MHz MPC866 microprocessor with 64 MB of total memory. Application programs use 51.389 MB of dedicated RAM. The controller executes 1000 boolean operations in 0.09 ms. Up to 32 tasks and 32 applications run per controller node. Cycle times can be configured down to 1 ms.
Redundant configurations deliver a maximum hardware switchover time of 10 ms. The package includes base mounting hardware with a total weight of 2700 g. Dual RJ-45 ports provide 10 Mbit/s Ethernet connectivity. The unit communicates over CEX bus supporting up to 12 modules. Modulebus connectivity supports up to 84 redundant I/O modules across seven optical clusters. An internal 3.6 V lithium battery provides real-time clock and memory backup.
