RE: 24 Volt 1-Wire dry contact relay??

All - And be sure to add a "back-EMF kickback" diode strapped across the
relay, or you will blow out the DS2406 on the 8x1-Wire board (cathode goes
to the relays +V).

Best regards, Kelly Smith

You can purchase these at DigiKey and connect them to an 8x1 Wire board as
long as the relay coil can be powered by 12 volts or less at 50 mA or less
so that it can be driven by PIOA from a DS2406.:
