5V Relay 8 Channel Shield Module Board Optocoupler module for ARM AVR

Complies with international safety standards , the load control area and regional isolation for tank ;

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

Ising loose music authentic relay control ;

With the relay instructions , pull off, disconnect does not shine ;

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

The relay can control the various devices and the load ;

8 and 8 normally open normally closed contact ;

Blue KF301 terminals to the control line is more convenient.

Module size : 13.8*5.6*1.80cm/5.43"*2.20"*0.71"( L * for W * H )

With 4 fixing bolt holes , hole 3.1mm, pitch 131mm * 49.5mm

Finished by 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
