I overcame this problem (a few times now) by using optically isolated 20mA loop
I.Cs from HP, namely HPL4100 and HPL4200.
The remote unit is isolated from the loop, doesnt have to power the
loop (that comes from the master unit) and all you have to worry
about is tying together the two power wires that run the remote unit
with suitable tranzorbs.
The down side is they arent so cheap.
