Overview

HDM5740 four–circuit digital display controller adopts surface mounting technology and automatic placement machine production with strong disturbance resistance capacity. The controller supports input of several kinds of signals and can be used with a variety of sensors and transmitters to realize measurement display of temperature, pressure, liquid level, speed, force and other physical quantity. It can display measurement signals at four channels simultaneously and be equipped with 8–channel separate alarm output or 4–channel separate alarm output, RS485/232 communication and other output functions, thus suitable for systems to carry out inspection of synchronous measurement of multi–points.
