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 are 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: 24V power supply connected to the positive

2, GND: 0 v 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
