Advanced Gas Alarm Controller with ≤ 10W Power Consumption and ≤ 1000m Communication Distance
KAN121 Gas Alarm Controller
Product Introduction
It has two sets of built - in passive relay contact outputs, which can directly control solenoid valves and AC fans (AC220V) with a power less than 1100W. It allows for remote correction of detector sensitivity and zero - point adjustment, eliminating the need for on - site calibration using large - scale gas distribution equipment. It is equipped with an automatic fault detection function and can indicate the location and type of the fault. It can store 2000 historical records in different categories. It is optional to carry out the transformation work for a three - wire system. The system has a reserved communication interface, facilitating networking with third - party control systems.
