AI signal transmission distance
Thread Content
How far can an AI signal be transmitted using ZR-DJYJVP22 2x2x1.5mm2 cables? Can it reach 2000 meters?
1000m should be no problem; I’ve never tried 2000m……
I did the calculations; to achieve a voltage drop of 0.24V at 24V DC, 6 wires are required.
24V minus the wire voltage drop should meet the power supply requirements of the on-site instruments (for example, 21.6V).
I can’t even use it for 1000m. Too unreliable.
Anyway, it’s not used within the requirements of national standards; to some extent, it exceeds those requirements. I recall there being national standards for the power cables of instruments – you might want to take a look at those. Today’s instruments are not that fragile; they can still function when the voltage drops to 22V. A rough calculation can be done for reference.
