Power distribution units (PDUs) are crucial components of automation control systems, providing various signal conversion, transmission, and processing capabilities to meet the needs of industrial applications. PDUs can work seamlessly with different types of industrial sensors to collect parameter signals, isolate and transmit them to local and remote monitoring systems.
PDUs find extensive use in several industrial sectors, including machinery, electrical, telecommunications, power, oil and gas, chemical, steel, wastewater treatment, and building construction. They are primarily used for data acquisition, signal transmission and conversion, and PLC/DCS industrial control systems. PDUs complement the functions of analog I/O modules, enhance system flexibility, and improve reliability in harsh industrial environments.
