A smart relay vs standard contactors on a 6-stop MOD job
Just wrapped up a modernization on a 6-stop hydraulic setup over in Oakwood. We debated using a smart relay instead of the typical mess of contactors and timers. I gotta say, the smart relay saved us SO much time on programming and troubleshooting. The wiring alone took half a day less. Has anyone else made the switch on smaller jobs like this?

Forget what happens when a surge takes out the smart relay's power supply though.

Baker.simon has a point but I've been zapped by contactor coils way more times than I've had a smart relay fry on me. On a 6-stop job the cost savings in labor alone makes it worth carrying a spare power supply in the truck. Still won't stop me from reaching for my meter with my tongue halfway out though.
