I really need some help with a home automation project. I am looking for a relay to fulfill the following requirements and need some recommendations. I have searched all over and I must be using the wrong terminology for this relay, because I can't find what I am looking for.
I need to use a dry contact closure to activate the relay (input). I have taken measurements and it is truly dry contact, not low voltage. I have seen suggestions that require me to add a voltage source to input and I'd like to avoid this because I am not confident that the source can handle the additional voltage.
On the output side, I would prefer SPST Type C (both NO and NA options - if I am using terminology correctly). But a NO (type A I think) would suffice if type C is not possible given the input requirements. I am controlling 12V DC load, but would be happy if it could handle 5V DC as well for future use.
Price needs to be sub $20 each as I need 6 of these relays.
As far as form-factor, I am wiring this up to home security type devices (16ga wire in most cases) - so something that is either pre-wired or has a plug in option might be best. But I can work with anything that I can solder to or use crimped wire connectors, etc. Price and function are more important than form to me in this case.
TIA if anyone has ideas!
