5V 2 Channel Relay Module

This is a 5V, 10A 2-Channel Relay interface board. It tends to be utilized to control different apparatuses, and different types of gear with enormous current. It tends to be controlled straightforwardly with 3.3V or 5V rationale signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL rationale).

It has a 1×4 (2.54mm pitch) pin header for interfacing power (5V and 0V), and for controlling the 2 relays.

Pin Details:-

• 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

Specification:-

• High current relay, AC250V 10A, DC5V 10A
• 2 LEDs to indicate when relays are on
• Works with logic level signals from 3.3V or 5V devices
• Opto isolation circuitry
