5V Dual Channel Relay Module with Optocoupler

This is a 5V Dual Channel Relay Module with Optocoupler for Arduino PIC ARM. It can be used to control various appliances and other types of equipment with a large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

This 5V Dual Channel Relay Module has a 1×4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays.

The pins are marked on the PCB as:

• GND – Connect 0V to this pin.
• IN1 – Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
• IN2 – Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
• VCC – Connect 5V to this pin. Is used to power the optocouplers
