Description: 

This is a 5V 4-channel relay interface board.It can be used to control various appliances and equipment with large current. It is equipped with high-current relays that work under AC250V 7A ,125V 12A or DC24V 12A. It has a standard interface that can be controlled directly by microcontroller.

Circuit Diagram

Input:

• VCC: Positive supply voltage 5V

• GND: Ground 

• I1 - I4: Relay control port 

Output:

• Connect a load, DC 24V/12A，AC 250V/7A 125V/12A

Features:

• Easy to use with Arduino, Raspberry Pi,AVR, PIC, ARM, 8051 and other microcontrollers or low voltage circuits

• It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc

• There are four mounting holes at each corner of the board, easy for install and fix. The diameter of the hole is 3.2mm 

• High quality relay is used with single pole double throw, a common(COM) terminal, a normally open(NO) terminal, and a normally closed(NC) terminal 

• Green LED Status indicators to indicate the relay ON/OFF status.

• The maximum output of the relay: DC 24V/12A，AC 250V/7A 125V/12A

• Size: 95mm (Length) * 39mm (Width) * 19mm (Height)
