The PM862K01 is a logic controller module from ABB and belongs to the PM862 series. The PM862K01 is an integrated microprocessor and RAM memory CPU unit with a real-time clock, LED indicator, initialization button, and CompactFlash interface.
The module supports CPU redundancy to improve system availability and reliability. In addition, the PM862K01 has two RJ45 Ethernet ports (CN1, CN2) and two RJ45 serial ports (COM3, COM4) for connection 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.
The PM862K01 controller unit also supports a simple DIN rail connection/removal procedure using unique sliding and locking mechanisms. All substrates are equipped with a unique Ethernet address that provides a hardware identity for each CPU. In addition, the module features a clock rate of 67 Mhz, 32 megabytes of memory, and 0.18 milliseconds of performance.
Overall, PM862K01 is a high-performance, highly reliable logic controller module, widely used in industrial automation, process control, energy management and other fields.
