## Description

Product Description 4 Channel Relay Module, 4 Channel Relay Module Board with Optocoupler High & Low Trigger Module for Arduino 5V/12V/24V(5V) Specification Module interface 1. DC + : connected to the positive pole of power supply (voltage is required for relay, 5V, 12V and 24V for choice) 2. DC- : connect to the power negative pole. 3. IN1-IN4: according to the setting of each circuit, the corresponding relay can be controlled with high or low level to suck in. Relay output terminal: with 12 lines of interfaces, all interfaces can be directly connected to lead, convenient for users to use 1. NO1--NO4: the relay normally opens the interface, and the relay is suspended before it is sucked in, and is connected with COM after it is sucked in. 2. Common interface of relay COM1--COM4. 3. NC1--NC4: relay normally closed interface. The relay is short connected with COM before it is sucked in and suspended after it is sucked in. High and low level trigger selection terminal 1. S1-S4 is the high-low level trigger selection of relay 1-4 channels successively; 2. Com and low short connection, the corresponding relay for low level trigger, com and high short connection for high level trigger. Package List 1 x Relay Module

Review: Used with 12v push buttons to control 240v lightning. - Really cool and so easy to use! I ordered single module to test it and ended up with this one as I wanted to control 2x under cabinet lights and 1x ceiling LED in the living room. All devices are smart but I wanted to have an option to ON/OFF them in case of Home Assistant failure. So I figured out, that the easiest and safest way will be to used 12v push buttons in the worktop and they worked really well with this device. Just needed to swap the yellow jumper to low voltage as it didn't work at the beginning. Really cool device.
Review: All good so far, it appears to work well. - Appears to work very well I'm only holding off from a full five stars because I don't know how long it will last.

## Features

Appears to work very well I'm only holding off from a full five stars because I don't know how long it will last.

### ⭐⭐⭐⭐⭐ Worked out of the box without issues
*by A***A on 20 April 2022*

This a great interface board. The board needs a 5v DC supply for the relay coils but are driven by drivers which can be triggered using 3,3v so ideal for IOT devices like Arduino, ESP, Rasoberry Pi etc It can also use either logic hi or low switching by the use of jumpers on board.
