Description
The PM864A is a high-performance controller module designed by ABB for the AC800M distributed control system (DCS), delivering advanced processing capabilities and seamless integration for critical industrial applications. As part of ABB’s industrial automation portfolio, the PM864A supports complex control logic, real-time data processing, and communication with a wide range of field devices. Its modular architecture and rugged design make it ideal for industries such as oil and gas, power generation, water treatment, and manufacturing.
The
PM864A serves as the core processing unit in ABB’s AC800M system, enabling precise control of industrial processes through its dual-core ARM Cortex-A9 processor and 256 MB RAM. It supports multiple communication protocols, including Ethernet, PROFIBUS DP, and Modbus TCP, ensuring compatibility with legacy and modern systems. With a wide operating temperature range (-25°C to +70°C) and shock/vibration resistance, the module withstands harsh environments typical of industrial settings.
