Product Description:

        This is a 2 Channel isolated 5V 10A relay module 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 relay has a 1×4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays.

Features:

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