The DT1102 ROOT (PS) provides galvanic isolation and signal conversion between the transmitter (or another signal source) and the signal processing unit.
The transfer characteristics is square root. See figure above for 4-20 mA input / output.
The galvanic isolation is 3-way: the input, output and power supply are galvanically isolated of each other.
The continuous isolation voltage is 250 VACeff in all three directions
The instrument provides 20 VDC / 24 mA on the input for supplying passive two wire transmitters.
The input and output signal ranges can be selected in any combination using the front switches:
