ABB PM866AK01 AC 800M Processor Unit
The ABB PM866AK01 (Order Number: 3BSE076939R1) is a high-performance processor unit designed for the AC 800M distributed control system (DCS). Operating on a 24 VDC supply (19.2 to 30 VDC range), it provides deterministic processing, real-time control, and network communication for demanding industrial automation environments.
Processor Performance and Memory Architecture
Driven by a 133 MHz MPC866 processor, the unit delivers an execution speed of 0.09 ms per 1,000 Boolean operations. Its onboard memory architecture includes 64 MB of total RAM (with 51.389 MB allocated for applications) and 4 MB of flash memory, supporting up to 32 applications, 64 programs per application, and 32 tasks with a minimum cycle time of 1 ms.
System Integration and Kit Contents
The controller features dual 10 Mbps RJ45 Ethernet ports supporting MMS and IAC protocols, alongside two RS-232C serial interfaces and a CEX-bus expansion capacity for up to 12 modules. The complete PM866AK01 package includes the PM866A CPU module, a TP830 baseplate, bus terminators, and a 3.6 V lithium backup battery.
