## Description

Keenso 4 Channel Relay Module, 5V Relay Board with Optocoupler, High & Low Trigger, 5V/12V/24V : desertcart.co.uk: Business, Industry & Science

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

- 【Fault-tolerant Design】This 4 Channel Relay Module with Fault-tolerant design,even if the control line breaks,the relay will not move. Power indicator light (green), 4-way relay state indicator light (red).
- 【Stable Performance】The Relay Board adopt patch photocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA. The module can be high or low by a jumper setting trigger.The module uses genuine quality relay, normally open interfaces.
- 【Humanized Interface Design】This 4 Channel Relay Module with Humanized interface design, all interfaces can be directly connected through the terminal lead, very convenient. Four fixing bolt holes are provided. Standard interface that can be controlled directly by microcontroller ( ,, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic);
- 【More Choice】 Relay module operating voltage is 5V,12V,24V for choice. Each path of the module can be triggered by the high level or low level through a jumper setting.
- 【after-sales service】We stand behind all of our them with a product guarantee and promise to give you the best in customer care! If you have any issue about the 4 Channel Relay Module, please contact us by e-mail, we will try our best within 24 hours to reply.

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.
