Anyone know anything about sending a signal down a wire a fair distance? In the region of 500m but say 1km for safety.
I basically want to operate a relay at one end from a signal at the other. All a bit hypothetical at this point but if anyone has any experience with such things be great to hear.
My knowledge is near zero. Likely I'd need to transform the signal to something that likes going a long way through cables and get a cable that keeps the signal intact. Can it be done analogue? Reliably?
