8 channel relay module

Features

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

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.
