PM861 3BSE018129R1 | ABB AC800M Processor Module

Description

The PM861 3BSE018129R1 is a processor module for the ABB AC800M control system, with technical specifications and features aligned with the closely related PM861 series processor units. It is equipped with either a PowerPC 604e or ARM Cortex-A9 main processor (varies by version), running at clock speeds of 400 MHz or 800 MHz to support high-speed data processing and control logic execution. The module includes 256 MB RAM and 1 GB Flash memory to store control programs and process data, and supports multiple communication interfaces including Ethernet, Modbus, Profibus-DP, and CANopen for seamless integration with industrial field devices and other control components.

With a compact footprint measuring 119 mm in length, 135 mm in width, and 189 mm in height, and weighing approximately 1.15 kg, it is designed for space-efficient installation in control cabinets. It operates reliably across a temperature range of -40 degrees Celsius to 70 degrees Celsius, with an input voltage range of 12-48 VDC, output voltage of 5 VDC, maximum output current of 10 A, and power efficiency greater than 90%. As a core component of industrial automation systems, it is engineered to control and coordinate diverse industrial processes and equipment, with a modular design that suits applications requiring high reliability, high security, and flexible configuration, including process control, machine control, and automated packaging lines.
