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.
