Voltage or current? Either way, chaining relays (or maybe a transistor) would be the answer. I.e. use a 10mA output to run a transistor, providing the 250mA that the relay needs. Use a parametric search (like digikey, mouser) to find a relay with a low voltage coil and high voltage/current contacts.
- hacknewslogin 4y agoIt's probably both, I haven't checked the current requirements yet. I was originally planning to use a raspberry pi zero. the GPIO pins put out 5 or 9v, but the relays that handle 240v run on...I think it was 12v.
- dicknuckle 4y agoWhat about Solid State Relays? I think one of mine takes 5v-30v input and I switch mains with it.
- hacknewslogin 4y agoawesome, I'll look into it. Thanks!
