Hi,
I've got a piece of equipment that's powered by 220V service and I need to remotely switch it on and off from the internet. I've got a nice rack mount 110V power switch with network interfaces and I was thinking I could just wire up a relay to do that job. The following are my newbie questions:
1. I found the omron Z2872-ND relay at digikey.com by searching for a 220V 25 Amp relay with Control Voltage On of 96 VAC. The next higher control voltage in the search form was 150 VAC. Even though the datasheet says (MAX), I presume that's the voltage required to turn on the relay, therefore for a 110 VAC control circuit I should choose the 96 VAC part. Is that correct?
2. The relay has four terminals which I think the control and power wires. Does that mean to switch my 220 VAC service I need to use a relay for each leg of the circuit?
Thanks
Chris
