You probably wouldnot get a full 24v, but I have seen circuits getting about 8 volts from this line. It also depends how much the loop of 4-20ma is powered up with.

4 mA max

The current drawn must be lower than 4 mA unless the data you are sending over the line will never be a value represented by low currents.
