Power supplies for 3 wire transmitters can be either ac or dc.
Ac voltage transmitter 4 20ma.
Din rail and field mount version are available.
When deciding on what voltage of power supply to use for your particular setup be sure to consider that the power supply voltage must be at least 10 greater than the total voltage drop of the attached components the transmitter receiver and even wire.
The use of improper power supplies can lead to equipment failure.
