220V relay board power on time delay circuit module D1B5

after the 220V is connected the output voltage is delivered to the load immediately and the load power is broken when the delay arrives. Direct power input direct 220V output. External power line load button can work. Easy to use. Adopt high quality original loose relay switch current up to 10A. It is equipped with normally open and normally closed points and can be connected as required. The length of time adjustment is adjustable continuously. One second to 60 seconds. The main control adopts NE555 monostable circuit and the time delay is accurate. Control part of power supply adopts RC step-down capacitor adopts X2 capacitor according to safety regulation step-down resistor adopts 3W high-power resistor filter capacitor up to 470uF to stable and reliable power supply. FR-4 glass fiber sheet is used to meet the requirement of city electricity and it is difficult to generate leakage arc. Be to adapt to all kinds of environment and temperature in electrical appliance. Board size: 65x38 mm with 4 mounting holes. Input: 220V Output: 220V current 10A (maximum 2200W) This module uses RC step-down debugging and installation please pay attention to safety installed in the product should pay attention to creepage distance requirements to prevent electric shock damage.
