Each channel connects three digital outputs of the Arduino directly to a 10 A relay, allowing even beginners to control motors, heaters, or lights without having to work on electrical installations.\u003c\/p\u003e \u003cp\u003eThe optoisolation between the inputs and the relay coils protects the Arduino board from feedback and interference voltages from the switching circuit. The four relays operate independently of one another and each switches a separately wired circuit, allowing several consumers to be controlled simultaneously or at staggered intervals.\u003c\/p\u003e \u003cp\u003eApplications include home automation, where pumps or valves are opened and closed on a timer, as well as experimental setups that switch LED lights and smaller DC motors. Controlling warning lights or activating electromagnetic locks are also among the possible applications. In every case, the logic runs on the Arduino, while the module provides the switching capacity.\u003c\/p\u003e \u003cp\u003eThe Arduino provides the control signals via four digital outputs. Power for the relay coils is supplied through a separate power input, which keeps the module independent of the Arduino's operating voltage. A separate external power source is required for the load connected to the relay contacts, providing 250 V AC or up to 30 V DC depending on the application. The jumpers on the module allow the coil voltage to be matched to the available external power supply.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eThis module is intended exclusively for building prototypes and for testing and development purposes, and is not intended for installation in household electrical circuits. Work on or near electrical installations and on high-voltage circuits must be carried out by qualified electricians; if you are unsure about safe wiring, consult a qualified electrician before commissioning. Avoid reversing the power supply polarity to prevent damage to the module.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x Relay Shield V1.3 Arduino compatible 4-channel \/ Relay Shield V1.3\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045674815837,"sku":"F23108531","price":8.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/relais-shield-v13-arduino-kompatibel-4-kanal-relay-shield-v13-funduino-4437682.png?v=1791492585","url":"https:\/\/funduino.com\/en\/products\/relay-shield-v1-3-arduino-compatible-4-channel-relay-shield-v1-3","provider":"Funduino","version":"1.0","type":"link"}
