DC 5V 8 channel relay module with optocoupler supports AVR / 51 / PIC microcontroller PLC pcb relay board


Product Description

It is an 8-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipments with large current.Relay output maximum contact is AC250V 10A and DC30V 10A.Standard interface can be directly connected with microcontrollers. Red working status indicator lights are conducive to the safe use.Widely used for all MCU control, industrial sector, PLC control, smart home control.


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
