12V 10A 8-Channel Optocoupler Relay Board Module are suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC. The relays used are rated up to 10A and have NO/NC contacts. Each channel has an LED indicator to show the relay is on.


  • Using high-current relay, AC250V 10A DC30V 10A
  • Contact some independent wiring, safe and reliable
  • Standard interface, can be extended in a variety of development board
  • With fixed screw holes for easy installation
  • Suitable for a variety of platforms such as 51/AVR/AVR/ARM
  • Connects directly to a micro-controller
  • LED Indicator for each channel


  • Input voltage: DC 12V
  • Input Current: more than 300mA
  • Connection : NC / COM / NO
  • Relay parameters:
  • The maximum you can control AC 250V, 10A DC30V 10A AC load, and maximum DC load.
  • Square onboard USB interface for connection stability
  • The use of imported high-performance USB controller chip
  • Use the special relay driver chip ULN2803, relay work more stable
  • Board power outlets and terminals, two kinds of access to power is flexible. After connecting the power, even if the computer off or unplug the USB from the computer, the relay can also remain set.
  • The module complies with international safety standards, the load control area and regional isolation tank;?
  • Using double-sided FR-4 circuit board design, high-end chip production process;?
  • Using loose music authentic relay control;
  • With the relay instructions, pull off, disconnect does not shine;
  • The signal input has a low signal, often beginning with a common terminal will be turned on;
  • The relay can control the various devices and the load;
  • 8 and 8 normally open normally closed contact;
  • Blue KF301 terminals to the control line is more convenient.
  • Module size: 138m * 56mm * 18.5mm (L * W * H), Weight: 120g
