This is a DC12V controlled 2 channel relay module. It’s high level trigger. Trigger current need not less than 5mA, It can be used in many industry system that using DC12V power supply.



  • SMD optocoupler isolation
  • Good in safety. In power system and high voltage system, the lower current can control the higher one, able to control various appliances and other equipment with high-current current.
  • Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
  • Indication LEDs for Relay output status.
  • With a normally-open (NO) and a normally-close (NC) contact.


  • Number of Relays: 2
  • Working voltage: 12V DC
  • Control signal: TTL level
  • Rated load: 7A/250VAC; 10A/125VAC; 10A/28VDC;
  • Contact action time: 10ms/5ms
  • Current: 15-20mA per channel
