Description
Process Controller is a high-performance industrial controller designed to measure, monitor, and control multiple process variables using a single panel-mounted instrument. Supporting thermocouple (J, K, R, S), Pt100 RTD, and 4–20 mA analog inputs, the controller provides a flexible solution for temperature, pressure, flow, level, humidity, and other industrial process control applications. Its 96 × 96 mm DIN panel-mount design makes it suitable for process industries, OEM machinery, industrial automation systems, and control panels requiring dependable and accurate process regulation.
