Note:
This module uses RC step-down, debugging and installation, please pay attention to safety, and creepage distance requirements, to prevent electric shock damage.
Function:
After connecting to 220V, the voltage is immediately output to the load, and the load is disconnected after the delay time arrives. (Note that this power-on starts to delay, no trigger signal is required)
Description:
Direct 220V input, 220V output. External power line, load or 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 delay time is adjustable continuously. One second to 60 seconds.
The main control adopts NE555 monostable circuit, and the time delay is accurate.
The 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 ensure stable and reliable power supply.
Use FR-4 glass fiber sheet, and it is difficult to generate leakage arc. Be able to adapt to all kinds of environment and temperature in the electrical appliance.
Board size: 65 x 38 mm, with 4 mounting holes.
Input: 220V
Output: 220V peak current 10A (maximum 2200W)
Package Included:
1 x 220V Relay Board
