Keenso 1 Channel 5V/12V/24V Relay with Optocoupler, High & Low Level Trigger

Nice bit of kit

Initially worked as it should. 12v pre amplifier trigger switched relay which fed 240 v to my power amp. Load was no more than 3 amps. Relay is now stuck. If 12v trigger is removed the relay state doesn't change unless I tap it with a screwdriver handle. I'm now returning it

I ordered single module to test it as I need at least 3 module device (so already ordered a 4 relay module). I used it to connect a 12v push switches in the work top to control 240v lights on the ceiling coving and under cabinets in the living room. It didn't work at the beginning but I switched the yellow connector on the pin to low voltage I believe, and it started to work. Not sure how long it will last but looks well built.

Very good relay dose the job.

Ideal for my e stop system

Works fine, I see there are a couple of negative reviews. You need to set the jumper to high and link +ve to IN if you don’t have a separate trigger, then it works fine when voltage applied. Hope that helps

Didn't work on first connection, straight in the bin...... Why oh why are earth's resources used by china to make defective rubbish, then shipped halfway round the world only to end up in local landfill. What is the point? The sooner the world wakes up to this the better chance we have of beating climate change.

Does the job. Using this to detect when mains power fails which then turns on a light in a radio studio. Cheap and it works!

Fonctionne comme prévu

Habe dieses Relais bei meinem Garagentorantrieb verbaut um ein externes Licht mit anzusteuern. Bedenkt man das das Originalteil zu meinem Torantrieb ein zigfaches gekostet hätte wobei dort das gleiche Relais verbaut ist handelt es sich hierbei um ein echtes Schnäppchen.
