Module Description :
 1. the module complies with international safety standards, the control area and the load region isolation trench.
 2. using double-sided FR-4 circuit board design , high-end chip production process.
 3. using loose music authentic relay control.
 4. with relay instructions , pull off, disconnect does not shine.
 5. there are low-level signal input signal, the common terminal will start with regular conduction.
 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 through 100% functional testing and stability testing

Module interface :
 1. VCC: 5V power supply connected to the positive
 2. GND: 5V power supply connected to the negative
 3. IN1-IN8: signal triggers the end , active low

Relay outputs : There are 12 line interface, all interfaces can be connected directly leads, user-friendly
 1. NO1 - NO8: normally open relay interface, the relay becomes vacant before , pull short after the COM
 2. COM1 - COM8 Relay Common Interface
 3. NC1 - NC8: normally closed relay interface relay shorted to COM before , pull vacant post
