Timing Relay Module Timing Relay Switch On Off Timer Switch With 1a

The module is printed with clear markings for easy wiring.After power on, the relay goes on a non-stop on/off cycle.1A fuse added for better protection of the module.Adjustable on/off time range from 1sec to 20sec.Relay on/off time is adjustable by rotating two potentiometers on the module.Item Type: Time Relay ModuleOperating Voltage: 220VDelay Range: 1-20 secondsTime Adjustment:The potentiometer marked with OFF-TIME on the module adjusts the time when the relay is off. Clockwise rotate the potentiometer to increase time, counterclockwise rotate the potentiometer to reduce time.The potentiometer marked with ON-TIME on the module adjusts the time when the relay is on. Clockwise rotate the potentiometer to increase time, counterclockwise rotate the potentiometer to reduce time.The EC1 capacitor on the module (beside the two time potentiometers) is 470uF timing capacitor. The user can increase the capacitance of the capacitor to make time adjustment range larger.Note: Be sure to pay attention to the electricity safety when testing, and must be powered off when wiring. When power is applied, no part of the module can be touched by hand or conductor. Adjust the time resistance and then power on to test until adjusting to the time you want. Power-on debugging is faster, but it is very dangerous. If the screwdriver hits the board and your hand comes into contact with the screwdriver, an electric shock will occur, endangering personal safety.colour:As shownMaterial:pcb boardsize: 5 x 5cmPackage Contents:1 x Time Relay ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
