4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Very compact design that can fit on top of Arduino UNO. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4 inputs connected to D8 To D11 of Arduino digital pins through solder jumpers J1 To J4. All trigger inputs can be connected to other I/O pins of Arduino using female header connectors and you will need to open solder jumpers J1-J4 in this case.  D1, D2, D3, D4 LEDs provided to indicate the Relay ON/OFF status. D5 is Power LED. Each relay has 3 pin screw terminals with normally open/normally closed switch to connect the load. Project is ideally used for low voltage applications and requires extra care in case of using high voltage AC switching.

Features

  • Input supply 12 VDC @ 170 mA ( Arduino DC Jack)
  • Output four SPDT relay
  • Relay specification 7A/24V DC-230V AC
  • Trigger level 2 ~ 5 VDC
  • Header Connector for connecting power and trigger voltage
  • Solder Jumpers J1, J2, J3, J4 Interface Arduino Pins D8, D9, D10, D11
  • LED on each channel indicates relay status
  • Power Battery Terminal (PBT) for easy relay output
  • PCB Dimensions 68.37MM x 51.91 MM
