AEDIKO 2pcs DC 24V Relay Module 2 Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger

A good little relay that easy fits in a single gang surface box.

The media could not be loaded. Works perfectly, used to switch polarity of toy train track to have train continuously go back-and-forth on a short run of track.. and why not ?

I've only given this unit 4 stars because it's a replacement for an identical product I bought two years ago which has stopped working after only modest use, however while it was working it worked extremely well.

very easy to use

The media could not be loaded. I used this product as an interface between a photoelectric sensor and an indicating beacon. The sensor output wouldnt have the power to drive anything substantial so I added the relays to allow uprating the switching ability of the sensor. The driven beacon has 2 lights and a buzzer. This relay could drive upto 230v 10AMPs so could be used to stop and start a hoover with a current sensor etc to get automatic stop start of a hoover with 230v power tools etc. The ideas are endless.I use the 2 relays to seperate the light control and buzzer control for my little project.

Nothing

Item is as described, works exactly as hoped, i did have to google for the instrcutions to be sure i was using it correctly, otherwise it would have been 5 stars
