....but mate this with a 99-cent (free-shipping from Asia) eBay relay module, set the current to max (45 mA) and for $3 you have an insulated-rail relay module for gate-crossing mechanisms, dual-aspect signals, etc.. Again, this means you must know which end of a soldering iron to hold, but I believe this would be the lowest cost ever for an insulated-rail relay module.

Okay Stan, where is the eBay link/item number for "99 cent ... relay module" for those of us who do not keep up with this stuff.

You and GRJ are terrific contributors to the content here--THANK YOU BOTH.
