AD-TWT 24 GM

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.

AD-TWT 24 GM

Application
