The RB-KY combustible gas alarm controller is a high-tech product developed by our company, which can be matched with the RB-TTy, RB-TZy, and RB-TZS (4-20) mA standard signal output point gas detectors developed by our company to form a powerful gas alarm control system. It can also output a standard signal of (4-20) mA and connect to a secondary (or DCS) instrument. The controller unit receives the 4mA-20mA signal transmitted by the detector unit, processes and logically analyzes it, and reflects it in the form of digital display and sound and light alarm, and links it with the connected fans, magnetic valves or other fire-fighting equipment.
