Hi,

What are the relative advantages and disadvantages of having a voltage output as against a current output?

RE: voltage output

Of what?  Do you mean a constant-voltage power supply versus a constant-current one?

Current signal is less susceptible to interference.

RE: voltage output

Perhaps at least as important as eliminating voltage drops as a problem, many 4-20 ma sensors are powered by the current below 4 ma.  This means that only two wires are required for power and the signal.
