Signal Output

Greetings!

If I will run my output signal from relay and bring it into one location of around 300 meters far, will it still be energize? I am just curious on geting drop / losses on wiring a signal.This is for monitoring purposes.

Thank you very much for feedbacks.

Hi,

I think 300m should be okay. But it depends on ur cable type.

U can check & calculate as per below link.

It depends on the size of the wire and the type of relay you will use.

Depends on the type and make of relay

IDEC Subminiature SPDT relay with 1.5va coil burden - no problem.

Had this discussion in the shop years ago and grabbed a 1000' box of 24ga. telephone wire and drove the relay just fine

with a 300 mtr run I would be worried about induced voltages from other sources.so consider a shielded cable.
You may energise the relay only to find it stays energised.
