Solenoid for Ro/Di

Glad to see it worked out as a quick fix. Good idea to look for a purpose built 24 VDC adapter as well, though. Intent of my earlier post was not to critique your work, merely to recommend that an adapter more suited to the requirements would be a better long term solution. Having the rectifier exposed outside the adapter housing with no protection could be an issue. You might consider protecting it somehow.

that transformer provides total isolation from your house voltage, the 24v side is basically harmless even if you short circuit it, just don't put it in your mouth, you could tape up the wires but I would leave the plastic parts of the diodes exposed to the air, you probably did a better job on that then anything you could buy out of china.
