ABB PM860AK01 3BSE066495R1 Processor Unit

Processor Performance: Equipped with a 32-bit RISC processor with a main frequency of 300MHz and a computing capacity of 50 MIPS (million instructions per second). It supports multi-task parallel processing and can stably run 100-200 control loops.

Memory Configuration: Built-in 256MB DDR2 RAM (with ECC verification), 128MB Flash program memory, and supports SD card expansion storage (up to 16GB) for storing historical data and configuration files.

Communication Interfaces: Equipped with 1 10/100Mbps Ethernet interface (supporting Modbus TCP/IP) and 1 RS-485 serial port (supporting Modbus RTU). The Ethernet interface supports communication with upper computers or HMI (Human-Machine Interface) with a maximum transmission rate of 100Mbps.

Power Parameters: Adopts 24VDC DC power supply, with an allowable voltage fluctuation range of ±10% and a rated power consumption of ≤8W. It has overvoltage (≥30VDC) and undervoltage (≤18VDC) protection functions.

Environmental Adaptability: Operating temperature ranges from -20℃ to +60℃, relative humidity from 5% to 95% (non-condensing), and protection class IP20 (must be installed in a control cabinet). It has passed the IEC 61000-6-2 industrial anti-electromagnetic interference certification and can withstand vibration (10-500Hz, 5g acceleration).

Mechanical Specifications: Dimensions are 120mm×80mm×60mm (length × width × height), weight is about 0.3kg. It supports DIN rail mounting, has a compact structure, and is suitable for installation environments with limited space.

Compact Design and Low-Power Operation: Adopts a miniaturized package, with a volume 40% smaller than that of high-end modules in the same series, making it suitable for installation in small control cabinets or equipment integration boxes. With a rated power consumption of ≤8W, it can be directly powered by the on-site 24VDC power supply, reducing the system power supply cost. It is particularly suitable for distributed control scenarios (such as the extension control of small production lines).

Simplified Programming and Quick Integration: Supports IEC 61131-3 standard programming languages (mainly ladder diagram and function block diagram). Lightweight configuration is carried out through ABB Control Builder M software, which provides preset control function blocks (such as PID, logical AND gate). Engineers can quickly complete program writing, and the debugging cycle is shortened by 30%.

Reliable Operation and Fault Self-Diagnosis: Built-in hardware watchdog circuit, which can automatically reset within 100ms when the program runs abnormally. It has basic self-diagnosis functions, which can monitor the power supply voltage and communication link status. Fault information is intuitively displayed through LED indicators (power, operation, communication), facilitating quick on-site troubleshooting. The mean time between failures (MTBF) is ≥200,000 hours.

Flexible I/O Expansion Capability: Through the CI853 communication interface module, it can be expanded to connect digital I/O modules (such as DI810, DO810) and analog I/O modules (such as AI830, AO830) of the AC 800M series, supporting a maximum of 128 I/O channels, which meets the signal collection and control needs of small and medium-sized production lines.

Convenient Remote Monitoring: Supports communication with upper computers (such as SCADA systems) via Ethernet, and can upload equipment operating status and process parameters in real time. It supports the Modbus RTU protocol and can be directly connected to small HMI panels to realize local visual monitoring (such as displaying temperature, pressure values and equipment start-stop status).
