  • 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.
  • Connects directly to a microcontroller
  • LED Indicator for each channel


Module Description: 

  • 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 
  • With 4 fixing bolt holes, hole 3.1mm, pitch 131mm * 49.5mm 
  • Finished by 100% functional testing and stability testing
