Reading the web site concerning the 3051, it states:
"The relays can switch up to 240 V AC at 10 Amps and 100 V DC at 5 Amps."
I am confused though, because looking at the relays themselves, they are labeled "10A125V~". I understand this limits them to 125V at 10A.
I'm no electrician, but this seems wrong to me. I'm hoping someone can explain what I am missing. I want to switch a 240VAC 4A load with this relay.
I thought maybe the expectation was to switch each leg of the 240VAC line with a separate relay. The problem is that the load does not use the neutral wire and just connects the two hot wires at the load device, as is common with 240VAC, so the power of both legs would run through both relays. That's the same as switching with one relay: it pushes too much wattage through the relays. Or does it? Like I said, I'm not an electrician.
My assumption is that I simply don't understand something basic. What am I missing? I don't want to burn the relay board out.
