This board enables users to control 2 x relays remotely. The 2 channels can be controlled remotely using a webserver\/WiFi connection. The project works with 5VDC. Two LEDs indicate relay operation. Screw terminals help user to connect devices and power the supply. Relay output has 3 contacts normally closed, normally open, and common. Relay can drive a load up to 10A\/250VAC or 10A\/30VDC. It can be used in applications such as IoT and smart Home\/Home automation.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe board can be connected to a server through a TCP Client and also can be controlled by HTTP. With this module, users can upload firmware and can create a versatile IoT project. It is suitable for your smart home and IoT project with network control.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eHardware Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eESP8266 MCUNODE (WiFi)\u003c\/li\u003e\n\u003cli\u003e2 x 5V Relay\u003c\/li\u003e\n\u003cli\u003e2 x LEDs Relay Operations\u003c\/li\u003e\n\u003cli\u003e2 x 3 Pin Screw Terminals (Relay Output Normally Open, Normally Closed and Common Connections)\u003c\/li\u003e\n\u003cli\u003e2 Pin Screw Terminal Power Input 5V DC\u003c\/li\u003e\n\u003cli\u003e2 x BJT (Transistors) drive relays\u003c\/li\u003e\n\u003cli\u003e2 x Flyback diodes\u003c\/li\u003e\n\u003cli\u003eESP8266 GPIO15 Connected to Relay 1\u003c\/li\u003e\n\u003cli\u003eESP8266 GPIO13 Connected to Relay 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Supply 5V DC\u003c\/li\u003e\n\u003cli\u003eCurrent 100mA (when Relays are on)\u003c\/li\u003e\n\u003cli\u003e2 x Relay LED\u003c\/li\u003e\n\u003cli\u003e4 x 3MM Mounting Holes\u003c\/li\u003e\n\u003cli\u003eScrew Terminal for Easy Connections\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 57.63 x 53.98 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections and Other Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1 Power Supply: Pin 1 = 5V DC, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN2: Pin 1 Normally Closed, Pin 2 = Common, Pin 3 = Normally Open (Relay 1 Contacts)\u003c\/li\u003e\n\u003cli\u003eCN3: Pin 1 Normally Closed, Pin 2 = Common, Pin 3 = Normally Open (Relay 2 Contacts)\u003c\/li\u003e\n\u003cli\u003eD2: LED for Relay 1\u003c\/li\u003e\n\u003cli\u003eD4: LED for Relay 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47241394323628,"sku":"C117","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/C117.jpg?v=1789715419","url":"https:\/\/dotfry.com\/products\/2-channel-wi-fi-relay-module-using-esp8266-node-mcu","provider":"dotfry","version":"1.0","type":"link"}
