Delay time relay for 12V 24V power off switch with trigger versionName: 1-way power off delay switchModel: YS-RT1DProduct specifications: 82*50*32mmPower supply voltage: DC 12V (7-13V)Trigger voltage: 12V version---4-15V trigger, 220V version--220V trigger (110V is not supported)Standby current: 11MAWorking current: 90MADelay time: time optionalOutput port: Normally open and normally closed, mechanical switch output portLoad type: incandescent lamps, energy-saving lamps, LED lamps, exhaust fans, automobile lines, etc. switch-controllable equipment.(The difference between the 12V version and the 220V version is that the detection voltage of the trigger port is different, but everything else is the same)12V version: trigger port voltage detection range 4-15V220V version: trigger port voltage detection range 110-250VSwitch working principle:This switch has a power-off delay shutdown function. The power supply of the 12V power supply port is a standing power supply. It can generally be connected to a battery or other adapter power supply. The trigger port is used to connect the detected signal or whether the power supply voltage is disconnected, thereby achieving related action.First, we connect the 12V standing power supply, and then if there is voltage at the trigger port, the switch will open. When the voltage at the trigger port is disconnected, the switch will automatically turn off after a delay; if there is voltage at the trigger port next time, The switch will turn on and you can cycle.Application scope:Household switch control--exhaust fans, cooling equipment and other household productsAutomotive electronic control - navigation, media sound effects, door and window delay lift and other automotive circuit power-off delay controlIndustrial equipment control--acce control equipment--warehouse, walkway lighting, etc.Test Methods:1. Connect the load circuit at the output port2. Connect to DC 12V standing power supply3. Select the delay time4. Connect the trigger port signal or power supply5. At this time, the switch has been turned on and the load has started to work. When the trigger port signal is disconnected, the switch has been turned off and the load has stopped working.Delay time selection method:The time is determined by flipping the red 4-digit switch to correspond to different delay parameters.
