220V Relay Board Timer Relay Delay Switch Module Input Output Delay Off Switch Module

Features: After connecting to 220V, immediately output the voltage to the load, and disconnect the load power after the delay arrives. Direct mains input, direct 220V output. External connection power cord, load, and button can work. Easy to use. Using high quality original Songle relay, switching current up to 10A. It is equipped with normally open and normally closed points and can be connected as required. Delay adjustment time length potentiometer is continuously adjustable. 1 second to 60 seconds. The main control adopts NE555 monostable circuit with accurate delay. The control part of the power supply adopts RC step down, the capacitor adopts X2 capacitor conforming to safety regulations, the step down resistor adopts 3W high power resistor, and the filter capacitor is up to 470uF to ensure stable and reliable power supply. FR 4 glass fiber board is adopted, which is suitable for the mains demand and is not easy to produce leakage electric arc. Can adapt to various environments and temperatures in electrical appliances.
