ITEM NAME:5V Relay 8 Channel Shield Module Board Optocoupler module for Arduino ARM AVR 100% brand new and high quality Complies with international safety standards , the load control area and regional isolation 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 * W * H ) With 4 fixing bolt holes , hole 3.1mm, pitch 131mm * 49.5mm 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 Quantity:1Pc Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! 1Pc x Module.3, NC1 - NC8: normally closed relay interface relay shorted with COM ago, after the pull- vacant. 1, NO1 - NO8: normally open relay interfaces, relay before the vacant after the pull shorted with COM.
