Isolation Transmitter
AD-TWT 24 GM


back to products

  Description

The isolation transmitter AD-TWT 24 GM in 2-wire-transmitter technique impress into a supply voltage a standard measurement signal of 4-20 mA. The output signal follows linear the input signal up to a maximum value. The connection of an additional auxiliary voltage is not necessary. It obtains its auxiliary energy from the transmitter supply.

  Application

Economical galvanical isolation of a active analog signal in a impressed passive 4-20mA signal ( 2-wire-transmitter technique).

  Specific characteristics

  • 2-wire-transmitter technique, low amount of cabling
  • output signal of 4-20 mA independent from supply voltage
  • compact design (DIN rail)
  •   Business data
