The module receives radio signals and switches its output to control connected devices such as electromagnetic contactors, valves, or small motors.\u003c\/p\u003e \u003cp\u003eThe module operates at a frequency of 433 MHz. The radio signal from the transmitter closes or opens a transistor output, which can switch up to approximately 2 amperes. For devices with higher current consumption or higher voltage requirements, a separate relay or MOSFET module is used as an amplifier stage.\u003c\/p\u003e \u003cp\u003eTypical applications include remotely controlled door openers and garage doors, alarm systems with wireless activation, and simple model controls. With a clear line of sight, the module offers a range of up to 500 meters; indoors, the usable distance is considerably shorter.\u003c\/p\u003e \u003cp\u003eA compatible transmitter module operating on the same frequency is required. The module already includes a 12-volt power supply, so no additional external power sources are needed. The emitter and collector of the switching output are connected via open contacts, so only low voltage may be applied here.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eThis module is intended solely for building prototypes and for testing and development purposes; it is not suitable for installation in household electrical circuits. Before commissioning it to control higher-power devices or for operation at mains voltage, consult a qualified electrician. Make sure the power supply polarity is correct.\u003c\/p\u003e \u003ch4\u003ePackage contents\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x Wireless remote control + receiver module, incl. 12V 1-channel relay, 433 MHz\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045685170525,"sku":"F23109092","price":9.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/funkfernbedienung-empfaenger-modul-inkl-12v-1-kanal-relais-433-mhz-funduino-7894027.jpg?v=1791492851","url":"https:\/\/funduino.com\/en\/products\/radio-remote-control-receiver-module-including-12v-1-channel-relay-433-mhz","provider":"Funduino","version":"1.0","type":"link"}
