• 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
