## Description

ELEGOO 4 Channel DC 5V Relay Module with Optocoupler Compatible with Arduino UNO R3 MEGA 2560 DSP ARM PIC AVR STM32: desertcart.com: Industrial & Scientific

Review: Ground triggered relay - These operate when you ground the input. Keep that in mind with your intended circuit. Out the box worked with zero issues. I upgraded 4 single relays to this and the design is much more compact. Good value for the money.
Review: Well made and tested top notch - I bought these to go with the Arduino board and have not used them yet. I did run tests on them to be sure they would work properly. They work great when tested and will function perfectly when programed. The board looks great, the soldering is clean and the parts are all well mounted. I have no doubt that it will work as advertised when it's time to go on the job.

## Features

- This relay module is 5V active low. Relay output maximum contact is AC250V 10A and DC30V 10A.
- Standard interface can be directly connected with microcontrollers.
- Working status indicator lights are conducive to the safe use
- 4-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipments with large current.
- Widely used for all MCU control, industrial sector, PLC control, smart home control.
