This product is a 5V 8 Channel Relay Module Relay Board with LED indicators, It can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V.

This relay board provides 8 optically isolated inputs that accept a wide range of voltage, including the 3VDC and 5VDC signals available on the Arduino. This is a great way to switch on or off AC or DC loads using your Arduino!
The relay module are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals.

This Arduino Relay Module Shield provides a solution for controlling high current devices that cannot control by the Arduino digital I/O pins because of their current and voltage limits.

The Relay Shield features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to show the on/off state of each relay. And the standardize shield from factor to provide a smooth connection to the Arduino board or other Arduino compatible boards.


  1. Imported high quality double sided compact PCB.
  2. Opto-Isolated inputs, means your digital electronics is safe and noise free.
  3. This relay module is 5V active low.
  4. It is an 8-channel relay interface board, which can  controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
  5. It is also able to control various appliances and other equipment with large current.
  6. 5v Relay output maximum contact is AC250V 10A and DC30V 10A.
  7. Standard interface can be directly connected with microcontrollers.
  8. Red working status indicator lights are conducive to the safe use.
  9. Widely used for all MCU control, industrial sector, PLC control, smart home control.
