Promotion 8 Channel 5V Relay Module with Optocoupler

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
