ABB PM866AK02 3BSE081637R1 Real-time Performance:
Minimum loop time 1 ms, execution time for 1000 Boolean operations 0.09 ms. Built-in 32 task priorities; a single controller can manage 32 applications, 64 programs, and 128 CFC diagrams. Event queue supports 3000 buffer entries; peak OPC transmission rate 143 messages/second, meeting the requirements of high-speed closed-loop, motion cascading, and Sequential Event Recording (SOE).
IV. Power Supply and Consumption: 24 VDC rated input, allowable range 19.2–30 V, typical power consumption 5.1 W, maximum 8.6 W. The module has a built-in 3.6 V/2.1 Ah lithium battery; RTC and holding register data retention ≥5 years after power failure. A dual-terminal redundant power interface allows connection to an external battery module (SB822) for further extended retention time.
Environmental Specifications
Operating temperature: -40 °C ~ +70 °C; Storage temperature: -40 °C ~ +85 °C; Non-condensing at 5%~95% RH. Vibration resistance: 0.5 g (5–500 Hz); Shock resistance: 15 g; Protection rating: IP20; MTBF > 400,000 h (Telcordia 25 °C). Certified by CE, UL 508, UL 61010, ATEX Zone 2, IECEx, and RoHS. Can be directly installed ithe n K3 nuclear power plant and Zone 2 explosion-proof enclosures.
Software and Protocols
Supports ABB Control Builder M V5.1–V6.1, compliant with IEC 61131-3 standards (LD, FBD, ST, IL, SFC) and CFC continuous function chart. Built-in redundant library RedLib automatically performs data synchronisation, fault diagnosis, and switchover management. Communication protocols include MMS, IAC, Modbus TCP, IEC 61850 GOOSE, and OPC DA/UA. These can be expanded via CI modules to include PROFIBUS DP, PROFINET, EtherNet/IP, and IEC 60870-5-104.
