ABB PM866AK01 3BSE076939R1 AC 800M Processor Unit module

The ABB PM866AK01 (model 3BSE076939R1) is a high performance processor unit designed for use with the AC 800M series of rail mounted modules. These modules are part of the ABB AC 800M series, which includes CPUs, communication modules, power supply modules, and a variety of accessories.The AC 800M series is designed to provide advanced automation solutions for a wide range of applications in different industries, including machine tools, construction machinery, printing machinery, speciality machinery, controller building, textile machinery, machine tool construction, packaging machinery, mounting systems, pick-and-place machines, electrical/electronic industries, assembly machines, automotive, palletisers, and other industrial applications. /electronics industry, assembly machines, automotive, palletisers, water/wastewater treatment, general mechanical engineering, and food and beverage.

Optimised for integration into these applications, the PM866AK01 processor unit provides a powerful and reliable platform for automation control. It features a CPU board with microprocessor and RAM memory, a real-time clock, LED indicators, an INIT button, and a CompactFlash interface for programme storage. The controller's backplane includes two RJ45 Ethernet ports for network connectivity and two RJ45 serial ports, one of which is an RS-232C port with modem control signals, enabling it to meet a wide range of communication needs. In addition, the controller supports CPU redundancy for greater availability, ensuring continuous operation even in the event of component failure.

The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a CompactFlash interface.

The base plate of the PM866 / PM866A controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with modem control signals, whereas the other port (COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).

Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base plates are provided with a unique Ethernet address which provides every CPU with a hardware identity. The address can be found on the Ethernet address label attached to the TP830 base plate.
