11+ 2 Channel Relay Board Circuit Diagram. This project is a 2 channel relay board. After 20 sec green led will start to blink (0.5 sec).at this time you can connect to your esp8266 chip which is.
This module contians two relays that are electrically isolated from the controlling input. Can be used as normally open (no) or normally closed (nc). 3d model of the sunfounder 2 channel 5v relay shield module for arduino.
The connections for connecting the relay module with arduino are very simple.
11+ 2 Channel Relay Board Circuit Diagram. Numato lab's 2 channel programmable relay module is a feature rich product that can be programmed the logic circuit uses +5v supply and the relay coils uses +12v supply. The 2 channel relay board is programmed to work with 2 modes. Switching capacity available by 10a in spite of small size design for features. The diagram shows an inner section diagram of a relay.
