Size: 6.8CM x 2.1CM\u003cbr\u003e2. Main chip: NE555\u003cbr\u003e3. Working voltage: DC 12V\/5V\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e1. The relay time delay and power supply is connected.Specific as follows: for 12V\/5V power supply to the relay, relay not immediately and absorption, relay the output status to: normally open and public disconnect, normally closed and public conduction;Wait for delay 1-10 s (adjustable), relay and absorption, at this point, the relay outputs status to: normally open and public conduction, normally closed and public disconnected;As long as the module power continuously, this state will remain.\u003cbr\u003e2. The delay time is adjustable, (0-10 seconds)\u003cbr\u003e4. Increase the potentiometer to increase the delay time\u003cbr\u003e5. Increasing the capacitor C1 can increase the delay time\u003cbr\u003e6. With input power indicator light\u003cbr\u003e7. With relay pull-in indicator light\u003cbr\u003e8. It can control AC 220V\/10A equipment. (Large control equipment 2000W)\u003cbr\u003e9. With relay freewheeling protection.\u003cbr\u003e10. Delay time formula: T=1.1RC. For example: capacitor 100uf resistor 100K T=1.1 x 100000 x 0.0001=11 seconds\u003cbr\u003e\u003cbr\u003eApplications\u003cbr\u003e1. The on-board equipment on the time delay, prevent excessive current when the car lighter burned on-board equipment.\u003cbr\u003e2. Need to have order to start the occasion, to prevent multiple devices at the same time starting current is too large burning appliances.\u003cbr\u003e\u003cbr\u003e","brand":"DropKart","offers":[{"title":"5V","offer_id":44041501671512,"sku":"TBD0604008801","price":2.48,"currency_code":"USD","in_stock":true},{"title":"12V","offer_id":44041501704280,"sku":"TBD0604008802","price":2.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0721\/3947\/2984\/files\/TBD0604008801.jpg?v=1777307655","url":"https:\/\/dropkartllc.com\/products\/ne555-time-relay-shield-timing-relay-timer-control-switch-car-relays-5v-12v","provider":"DropKart LLC","version":"1.0","type":"link"}
