12v relay board 8 channel relay 12v 

Module Description:

1, the module complies with international safety standards, the load control area and regional isolation

tank;

2, using double-sided FR-4 circuit board design, high-end chip production process;

3, using loose music authentic relay control;

4, with the relay instructions, pull off, disconnect does not shine;

5, the signal input has a low signal, often beginning with a common terminal will be turned on;

6, the relay can control the various devices and the load;

7, 8 and 8 normally open normally closed contact;

8, blue KF301 terminals to the control line is more convenient.
