4-Channel Relay(5V) Module Shield for Arduino ARM PIC AVR
4 relay output modules, relay output contacts maximum 250A 10A. Input IN1, IN2, IN3, IN4 signal line is active low. VCC, GND power input can be individually powered relay relay power input JD-VCC.
Uses:
1 , support all MCU control .
2 , industrial areas ;
3, PLC control ;
4 , smart home control ;
Features
Using high-current relay , AC250V 10A DC30V 10A
Contact some independent wiring , safe and reliable
Standard interface , can be extended in a variety of development board
With fixed screw holes for easy installation
Suitable for a variety of platforms such as 51/AVR/AVR/ARM
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, there are four normally open and normally closed contacts 4 ;
8 , blue KF301 terminals to the control line is more convenient.
9 , the module size : 75mm * 55mm * 18.5mm ( L * W * H ) , Weight : 61g
10 with 4 fixing bolt holes , hole 3.1mm, pitch 68mm * 48mm
11 , finished by 100% functional testing and stability testing is very convenient
Two module interface :
1, VCC: 5V power supply connected to the positive
2, GND: 5V power supply connected to the negative
3, IN1-IN4: trigger signal , active low
Relay outputs : a 12- line interface, the interface can be directly connected to all leads , user-friendly
1, NO1 – NO4: normally open relay interface, the relay before the vacant after the pull shorted with COM
2, COM1 – COM4 Common Interface Relays
3, NC1 – NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant
