Self Latching Relay
Posted: Mon Mar 21, 2016 7:35 am
I have been trolling the internet and have asked on other electronic forums, but since I want to use with the BCS, I am repeating it here.
Question:
Is there a board out there that will work? If so, could you point me to it.
What I need:
Self Latching Relay Board?
I am confused by what I found on the internet as it talks about manual buttons and triggers. I want one with a trigger to go from “NO” to closed.
I want a "switch" that is "NO" but electrically activated to "Closed". Once Closed, it stays that way until either manually or electrically returned to the "NO" State.
Basically I want to replace some manual Toggle Switches that I had planned set up on my Fermentation BCS. I am in the “building mode” now and while I have almost everything I need to start, I want to add automated switches that will jump to the correct State if I have a power outage while I travel.
I live outside of Dallas and we have frequent but brief power issues during Thunderstorm season. I do have the BCS on a Battery UPS.
This is my planned Process. I have the Toggle switches but have not wired my fermentation BCS yet.
It would be nice if the BCS could trigger the latching relay but I have no problems using an Out SSR to drive the trigger for the latching relay.
I will need to tweak this a bit but this is the "plan":
