Other names of PM856AK01:

Editable controller PM856AK01

PM856AK01 redundant processor

Processor unit PM856AK01

PM856AK01 is a processor unit in ABB’s AC 800M series controller. It is a modular, rail-mounted controller designed for industrial automation. It integrates CPU, communication module, power module and expansion interface, supports redundant configuration, and is suitable for complex control scenarios with high reliability requirements.

Core Features

Modularity and Scalability

Supports multiple I/O modules (such as S800 I/O), can connect up to 98 remote I/O stations (via Profibus DP bus), and supports local and remote installation.

Provides 12 fieldbus module expansion slots, supports Modbus, Profibus DP, Ethernet IP and other protocols, and has strong compatibility.

Communication Capability

Dual Ethernet interface: supports redundant configuration, built-in switching program, and improves network reliability.

Dual RS-232C interface: used for programming, debugging and communication with third-party devices.

Supports OPC Server service, which can be seamlessly integrated with HMI, SCADA and other systems.

High Reliability and Redundant Design

Supports redundancy of CPU, power supply, communication link and I/O, with a switching time of less than 10ms to ensure continuous system availability.

Fanless, enclosed design, adapts to harsh industrial environments and reduces failure points.

Powerful processing capability

Supports multi-tasking, can run up to 16 tasks, and the minimum task cycle is 1ms.

Built-in RISC 32-bit real-time processor, supports complex control algorithms (such as PID, fuzzy control).

Low energy consumption and compact design

The size is only 119mm (width) × 186mm (height) × 135mm (depth), and the weight is 1.2kg.

Low power consumption, no additional heat dissipation device is required, suitable for compact installation.

High-speed processing capability

Equipped with a high-performance processor, the computing speed is more than 30% higher than that of traditional PLC, ensuring the rapid execution of real-time control instructions, suitable for precise control of complex systems.
