High performance control unit PM866AK02
The PM866AK02 is a high-performance control unit from ABB that is a 40-channel analog output redundant module.
The main features and functions of the control unit include:
Redundant design: there are two identical analog output channels, each of which can independently output analog signals. This design can improve the reliability of the system, ensuring that when one channel fails, the other channel can continue to output signals, so as to ensure the normal operation of the system.
Analog output: can output voltage or current signals, used to control various industrial equipment, such as motors, valves, pumps, etc.
Integrated power supply unit and processor: The power supply unit, CPU processor and memory are integrated on the CPU board, which is compact and powerful.
Scalability: Support for up to 12 fieldbus module expansions provides flexibility for system expansion.
Communication interface: Integrated 2 Ethernet interfaces, 2 RS232C interfaces and ModulBus electrical and optical fiber expansion interfaces, support controller-level communication, and two of the Ethernet ports can be set to redundancy, improve system performance.
High reliability and accuracy: The use of high-quality materials and manufacturing processes ensures long-term stable operation in harsh industrial environments. The analog output signal has high precision, which ensures the stability and precision of the control system.
In addition, the PM866AK02 features a CPU clock rate of 133 MHZ, a performance time of 0.09 ms, 64MB of memory, and 51.389MB of RAM that can be used for applications.
Overall, the PM866AK02 is a powerful, high-performance industrial automation control unit suitable for complex industrial automation control systems requiring analog output.
PM866AK02 technical parameters mainly include the following aspects:
Interface:
The PM866AK02 controller has two Ethernet ports (CN1 and CN2) and two serial ports (COM3 and COM4) on the baseboard for connecting to the control network.
One of the serial ports (COM3) is the RS-232C port with the modem control signal, while the other port (COM4) is isolated and used to connect to the configuration tool.
CPU redundancy:
The PM866AK02 supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interface, and S800 I/O).
Others:
The controller has full EMC certification2.
All baseboards provide a unique Ethernet address, giving each CPU a hardware identity.
