E-HELP: Replacing Temperature Transmitters With Changing Power Sources

E-HELP: Replacing Temperature Transmitters With Changing Power Sources
Q: I want to replace a THZ Temperature Transmitter (Model THZ/PRG/4-20MA/12-42DC [DIN]) with a CPT PC-Programmable Temperature Transmitter (Model CPT/TPRG/0-20MA/117AC/-C-RF [DIN]). The THZ unit we are replacing gets its power from the 4-20mA current loop while the CPT unit is going to be powered by 120Vac. Does the CPT need to be specified as "source" or "sink" to work as a drop-in replacement for the THZ unit?
