8 channel relay module


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.
