DT1622 loop powered AC current and AC voltage transmitter-type designation

Product description

The DT1622 … Loop powered AC Current Transmitters provide an output signal (4-20 mA) proportionally
with the TRMS value of the input AC-current, AC-voltage signal.
The device is two wire transmitters without power supply. They are loop powered, the energy for operation charged from 4-20 mA current loop. The measured input is galvanic isolated from power network with wide frequency transformer.
The measure input compliance for overvoltage category CAT III.
The DT1622 I loop powered AC current transmitter available of range: 0-1 AAC / 0-5 AAC / 0-10 AAC / 0-15 AAC.
The DT1622 I build in 17.5 mm wide housing. The housing is mounting of TS-35 rail.
The transmitters are compliance for according EN 60688.
