Intended Use; Block Diagram - Knick SensoTrans R A 20230P0 Série Mode D'emploi

Intended Use

The SensoTrans® R A 20230 resistance transmitters provide connection
possibilities for resistors and potentiometers for angle, path, or posi-
tion detection.
When a resistive sensor is connected, 2-, 3-, or 4-wire confi guration is
automatically recognized at device startup.
The output signal is adjustable to 0 / 4 ... 20 mA, or 0 ... 5 / 10 V.
The calibrated range selection is performed using DIP and rotary
encoder switches. The device operates with a power supply of 24 V DC
and provides galvanic 3-port isolation.
