DK-C Controller (Wall Mounted)

Product Overview

DK-XXC large-screen LCD wall-mounted gas alarm controller (hereinafter referred to as the controller), using a wall-mounted structure, can receive up to 16 (4 ~ 20) mA signal input, using high-precision CPU chip. It can be used to continuously monitor the gases in the environment, display the measured gas concentration according to the received input signals, set two levels of alarm values, and send out different sound and light signals according to different alarm levels when the measured gas concentration exceeds the standard. Through the LCD display, you can observe the gas type, gas concentration value,gas concentration unit, and channel status (offline, normal, low alarm, high alarm,fault, burst meter, etc.) of each channel in real time.
