EQ2200DCU/EQ2200DCUEX數(shù)字通訊單元
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.
