Found this: http://www.rapidonline.com/electronic-components/high-sensitivity-relay-spdt-1a-62221

Seems to be a drop in replacement and has the advantage of being NO on the same side of the board as the original.

Datasheet here: http://www.rapidonline.com/pdf/60-2452.pdf

Can you see anything wrong with this part?

Remember that due to EU recommendations we are using PB free alloy. Due to fact that we like to have low melting point temperature, we are using not common used bismuth based alloy, which have small melting temperature. So, please to be careful when heating for de-soldering, because you can "loose" the other SMD components very easy, due to over heat and movements.
Warmest Regards

It is the same as we are using, same polarization.

Looks like the contacts are reversed no?

The normally closed contact would be bottom left rather than bottom right as per your relay.

Noted re: non-PB solder and low melting point. I'll keep the heating to an absolute minimum.

I check with multimeter, to be sure and seems to have the same polarity, I have the same relay from our production on my desk.
Please check with your one

No worry, I'll order 2 of them and depending on polarity I'll solder one to the top or bottom of the board, as required. They'll arrive tomorrow or Thursday from Rapid so don't worry about sending me the relays.

When they arrive I'll confirm which pin is normally closed/open.

Just a suggestion, but if you exposed both the NO/NC pins of the relay on the connector block then the same relay would serve both purposes. Maybe a jumper to choose NC/NO an then you wouldn't need an extra position on the connector block. Maybe for V2 UPiS.

Thanks for your help.

Any updates on the firmware issue when power comes back during shut-down?
For me it looks like a no-go for this system, at least for all the folks who are planning to deploy such a system remotely.
You are implementing so many bells and whistles, but missing out on core functionality.

Warmest regards

Hi, It is needed mainly for the remote using peoples. My colleague is working on that and very soon, hopefully next week it should be released.
