This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with 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).

It 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:-

• 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 opto couplers.

Features:

• 2 LEDs to indicate when relays are ON.
• Works with logic level signals from 3.3V or 5V devices.
• Opto isolation circuitry
• Module with diode current protection, short response time.
• Around the board with 4 mounting holes, hole diameter 3. 1 mm, easy installation and fixing.
