ABB PM866AK02

The ABB PM866AK02 is a high-performance redundant controller in ABB's AC800M series. Here is its detailed introduction:
- **Basic Information**
    - **Model**: PM866AK02
    - **Part Number**: 3BSE081637R1
    - **Dimensions**: 119mm in width, 186mm in height, 135mm in depth
    - **Weight**: 2700g
- **Performance Features**
    - **Redundant Design**: Equipped with two identical analog output channels, each of which can independently output analog signals. If one channel fails, the other can continue to work, ensuring the normal operation of the system.
    - **Analog Output Function**: It has 40 analog output channels that can output voltage or current signals to control various industrial equipment such as motors, valves, pumps, etc.
    - **Powerful Processing Capacity**: Built-in high-performance processor, reportedly a dual-core ARM Cortex-A9 with a main frequency of 800MHz, ensuring fast response and real-time data processing to meet high real-time requirements.
    - **Rich Communication Interfaces**: Integrates 2 Ethernet interfaces, 2 RS232C interfaces, and ModulBus electrical and optical fiber expansion interfaces, supporting controller-level communication. The two Ethernet ports can be set to redundancy to improve system performance.
    - **High Reliability and Accuracy**: Adopts high-quality materials and manufacturing processes to ensure long-term stable operation in harsh industrial environments. Its analog output signals have high precision, guaranteeing the stability and accuracy of the control system.
    - **Large-capacity Memory**: Equipped with sufficient memory, reportedly 4GB eMMC storage and 2GB RAM, supporting large amounts of program and data storage, and facilitating the implementation of complex control strategies.
- **Working Environment**
    - **Operating Temperature Range**: 0℃-55℃
    - **Relative Humidity**: 5%-95% RH (non-condensing)
- **Application Fields**
    - Suitable for industrial automation control systems requiring analog output, such as oil and gas exploration and processing, power generation and energy management, chemical and pharmaceutical industries, water and wastewater treatment, manufacturing automation, etc.
