Can I just say I really love this little relay. Well, actually it is larger (can’t hide it behind a light switch), but it is three relays in one with dry contacts and discrete switch inputs.
I’ve used it in a number of ways, which I’ll post about elsewhere in this forum. The most cool involve any place I need to send or receive signals from another system. This is because the dry contacts on the relay can be used to close a sensor on a foreign system; and the switch inputs can detect a foreign systems switch closing. It makes a great interface module of sorts.
The fact that it will operate on low voltage (12v DC) is a significant plus as well, allowing for a variety of use cases. I’ve powered this off of alarm system takeover modules - just need to be careful of the overall power budget - but it makes for a nice all in one solution.
