4 Relay Module 30A

This is a 4 channels Relay module, can able to control various appliances, and other equipment with a BIG current for 30A (250VAC/30VDC). It can be controlled directly by microcontroller: Raspberry, Arduino, AVR, PIC, DSP, ARM or TTL logic. For control of module need power 5V and logic operation 3.3V/5V. To isolate the microcontroller from the relay, we added optocoupler. Now with this configuration, the microcontroller doesn’t have any physical connection with the relay, it just uses the LED light of the Optocoupler IC to activate the relay. This solution saves your microcontroller from a high voltage for VAC/VDC.

Features:

  • Working voltage: DC5V
  • Max Control Capacity:30A@250VAC or 30A@30VDC
  • Active level: High or LOW(Set by 2x4 header)

Package List:

  • 1 x 4 Relay Module 30A
