Digital Communication Unit

The DCU is approved for use with a variety of Det-Tronics sensors including Pointwatch IR gas detector and hydrogen sulfide (H₂S) electrochemical sensor. It also accepts any sensor/transmitter with a linear 4 to 20 mA output signal and allows for one person non-intrusive calibration. The DCU digitizes the analog signal and transmits the value to the system controller. The DCUEX accepts our catalytic combustible sensor.
