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.
9 , Module size : 138m * 56mm * 18.5mm ( L * W * H ) , Weight : 120g
10 with 4 fixing bolt holes , hole 3.1mm, pitch 131mm * 49.5mm
11 , finished by 100% functional testing and stability testing
Two module interface :
1, VCC: 5V power supply connected to the positive
2, GND: 5V power supply connected to the negative
3, IN1-IN8: trigger signal , active low
Relay outputs : a 12- line interface, the interface can be directly connected to all leads , user-friendly
1, NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM
2, COM1 - COM8 Relay Common Interface
3, NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacant
Tips: choose the same channel, and will pay less freight
