Gas leakage cut-off valve

Gas leakage cut-off valveController features:

Adopting a two bus non-polar design makes the system wiring extremely simple, with arbitrary wiring paths and methods, and no particular order, improving wiring reliability, facilitating wiring construction and line maintenance, and greatly reducing project costs; Two wire design, compatible with the company's two wire sound and light, and also compatible with four wire equipment, with strong compatibility; WIFI debugging is divided into two modes: "internal network debugging" and "remote debugging". "Internal network debugging" can connect to the controller hotspot through a PC or mobile phone up close, complete the download, upload, and upgrade of engineering files, and also perform functions such as querying, setting, and installing the controller up close through a PC or mobile phone. Remote debugging "refers to connecting the controller to the cloud through a wireless network to achieve remote debugging functionality. Equipped with linkage programming function, it can meet various linkage logic requirements on the engineering site.
