00:06Okay so here's a question I get asked a lot, should you actually spend money on an Omron relay, or
00:11is a solid state relay good enough to replace it?
00:14Because these two things look similar on the shelf, plug in the same kind of circuit, and cost almost the
00:19same.
00:20I grabbed five different options, the best deals I could find, and we're going to break them down one by
00:25one.
00:26By the end you'll know which side actually wins.
00:30Starting with the classic.
00:31This is a 10-pack of SRD relays, SRD-12 VDC-SLC, SRD-05 VDC-SLC, the whole family, coil
00:39voltages from 3 volts all the way up to 48.
00:4210 amps at 250 volts AC, standard 5-pin footprint, so the sockets and modules everybody already owns will fit
00:49them.
00:50650 for 10 of them is honestly the best value in this whole list.
00:55If you're building a controller with more than one channel, this is the one.
00:59Now the solid state side of the aisle.
01:02Single-phase SSR, and the current rating is where these get fun, you can pick 10 amps, 25, 40, 60,
01:0980, 100, even 120 amps, and you get either AC or DC control input.
01:146.71 bucks, almost 5,000 sold, and people love them because there's no click.
01:20No moving parts, no coil whine, switching in milliseconds.
01:24If you're driving a heater or a motor starter, this is the workhorse.
01:29Then there's the big one.
01:31This LCTC is a 3-phase solid state relay, 25 amps up to 200 amps, rated for 380 volts AC,
01:38and you can control it with either AC or DC.
01:4120 bucks, but think about what you're replacing, 3 individual relays, 3 sockets, wiring 3 separate phases.
01:48This is one box doing the whole job.
01:51For a kiln, a kiln fan, a 3-phase heater, this thing is a no-brainer.
01:56But cheapest doesn't mean worst.
01:59This CGZ GT40DA is 384, and it comes with the heatsink already bolted on, the plastic cover fitted, 10-40
02:06amps, 24-480 volts AC output, 3-32 volts DC input.
02:11That heatsink is the whole ballgame with solid-state relays, because they dump heat as waste instead of making a
02:17click.
02:18Most people buy one of these and skip the expensive part.
02:22Smart.
