This is a LOW Level 5V relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with large current. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by microcontroller. This module is optically isolated from high voltage side for safety requirement and also prevent ground loop when interface to microcontroller.

DESCRIPTION:

• • 2-8 Channel Relay Module with Opto-coupler
  • Used to control various appliances and equipment with large current such as Motor, DC/AC Load , Lights and etc
  • Standard interface that can be controlled directly by microcontroller ( 8051, AVR, *PIC, DSP, ARM, ARM, MSP430, TTL logic), CNC controllers
  • Opto-Coupler isolation, for high voltage safety and prevent ground loop with microcontroller
  • Operating Trigger Voltage: 5V DC (3.3V in optocoupled mode without jumper and externa power supply)

 PINOUT DESCRIPTION

• VCC - Pin provides power to the built-in optocouplers and, optionally, the relay’s electromagnet (if you keep the jumper in place). Connect it to the 5V pin on the Arduino.
• GND - Is the common ground pin.
• IN1 ∼ IN8 - These pins control the relay. These are active low pins, which means that pulling them LOW activates the relay and pulling them HIGH deactivates it.
• JD-VCC - Provides power to the relay’s solenoid. When the jumper is in place, JD-VCC is shorted to VCC, allowing the solenoids to be powered by the Arduino’s/controllers  5V line. Without the jumper cap, you’d have to connect it to a separate 5V power source.
• VCC - This pin is shorted to the JD-VCC pin with the jumper cap on. Keep this pin disconnected if you remove the jumper.
