description: The digital displays DA are used as indicators by using external sensors with 0-10 V or 4-20
mA output. If necessary it can be used for adjust the zero-point of the connected sensor. At many applications the
sensor is installed at difficult accessible places. Therefore it is often difficult to adjust the zero-point direct at
the sensor. The digital-displays makes it possible to add or subtract a correction voltage or current to the sensor
signal.
The aluminium housing has a high mechanical stability and good EMV- properties. It is suitable for installation into a
control switchboard. If the input signal passes the critical value 20 mA or 10 V a red LED on the front indicates
the overload of the sensor. DA can be completed with several additional options: two switching outputs, RS232-interface
or 4-20 mA transmitter.
