This is the \u003cstrong\u003eNon-Latching Mini Relay FeatherWing\u003c\/strong\u003e. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board.\u003c\/p\u003e\n\u003cp\u003eUsing our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight.\u003c\/p\u003e\n\u003cp\u003eThe are two 'flavors' of these FeatherWings, this is the simple \u003cstrong\u003eNon-Latching\u003c\/strong\u003e relay. This Wing has a single Set pin. Normally, the relay's \u003cstrong\u003eCOM\u003c\/strong\u003e pin is connected mechanically to the \u003cstrong\u003eNC\u003c\/strong\u003e pin and the \u003cstrong\u003eNO \u003c\/strong\u003epin is disconnected.\u003c\/p\u003e\n\u003cp\u003eWhen the SET pin is pulled high, the relay switches and the internal switch changes so that the \u003cstrong\u003eCOM\u003c\/strong\u003e pin is mechanically connected to the \u003cstrong\u003eNO\u003c\/strong\u003e pin and \u003cstrong\u003eNC\u003c\/strong\u003e is then disconnected\u003c\/p\u003e\n\u003cp\u003eWhen the relay is active, a red LED is lit, and about 50mA of current is used to keep the coil switched on. Note, if power is lost, the relay will go back 'open'.\u003c\/p\u003e\n\u003cp\u003eNow, you might be thinking \"wow I really don't want to waste 50mA of current, that will really sink my battery life!\". OK good news, we have another type of FeatherWing, the \u003cstrong\u003eLatching FeatherWing\u003c\/strong\u003e. You need two pins but save power. Note, if power is lost, the relay will stay in the last setting.\u003c\/p\u003e\n\u003cp\u003eBoth FeatherWings use the same family of relay. You can switch up to 2A of resistive current at 30VDC or ~40VAC or lower. At 110VDC you can switch up to 0.3A, at 120VAC up to 0.5A, and at 250VAC you can switch up to 0.6A. Check the datasheet for the relay for the exact switching capacity, and of course, for reactive\/inductive loads you will need to derate. This isn't a relay you can use to turn on and off your washer\/dryer, stick to 60W or less.\u003c\/p\u003e\n\u003cp\u003eEach FeatherWing comes with a fully assembled and tested PCB, header you can use to attach to your Feather. You also get a 3-pin terminal block you can use to wire up whatever you are going to be relay-controlling. Some light soldering is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e If using with high voltages (\u0026gt; 24V) use care and common sense! High voltages require experience, and are only for use by engineers who are comfortable with guidelines and know how to use safely!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlso: \u003c\/strong\u003ethe terminal blocks included with your product may be blue or black.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/mini-relay-featherwings\/overview\"\u003eThe Adafruit learn guide covers everything you need to know for the Non-Latching and the Latching Mini Relay FeatherWings!\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"fluid-width-video-wrapper\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/d2rQurTNd38?start=133\" frameborder=\"0\" allowfullscreen=\"true\" class=\"youtube\" id=\"fitvid440778\" data-ss1508158353=\"1\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 id=\"tab_technical-details\" class=\"hidden-sm hidden-xs\" style=\"display: inline !important;\"\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003ca data-toggle=\"collapse\" href=\"https:\/\/www.adafruit.com\/#technical-details\" class=\"toggle-link\"\u003e\u003c\/a\u003e\n\u003cdiv id=\"technical-details\" class=\"panel-collapse collapse in-md in-lg \"\u003e\n\u003ca id=\"technical-details-anchor\" class=\"invizzy-anchor\" name=\"technical-details\"\u003e\u003c\/a\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003e50.8mm x 22.9mm x 11.4mm \/ 2\" x 0.9\" x 0.45\"\u003c\/li\u003e\n\u003cli\u003eWeight (just the board): 5.6g\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/mini-relay-featherwings\/downloads\"\u003eSchematic, Datasheet, EagleCAD PCB files, and Fritzing available in the product tutorial\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":32902095831172,"sku":"ADA-FEATHNONLATCH","price":12.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0368\/0337\/9332\/products\/2895-00.jpg?v=1584963862","url":"https:\/\/roboticles.myshopify.com\/products\/adafruit-non-latching-mini-relay-featherwing","provider":"roboticles","version":"1.0","type":"link"}
