It is the recommended transmission distance when the cable diameter is fixed and the 24V AC
power consumption is below 10%. For the AC device, the max permission voltage power
consumption is 10%. For example, when a device of rated power 20W installed from the
transformer 141 inches (42m), then the min cable diameter is 0.8000mm.
