Description
The digital indicator DI30 has been specially designed to display values measured by electronic transmitters, such as pressure transmitters or temperature transmitters.
Different input configurations for standard signals
0/4 ... 20 mA, DC 0 ... 5 V and DC 0 ... 10 V, are available, which can be selected via the terminal configuration and by the selection of the input signal in the instrument configuration.
Thereby alternatively transmitters with current or voltage signals can be connected to the same unit. By means of the transmitter supply current loop transmitters (2-wire) as well as 3-wire and 4-wire transmitters can be operated.
The transmitter supply is galvanically isolated from the measuring input.
There are two alarm outputs available.
In addition the indicator offers the possibility of sensor calibration and linearisation with up to 10 points, thus enabling a further adaptation to many different sensor signals and specific application requirements.
The standard features are completed by the adjustable sampling rate and display time as well as the input offset for the correction of zero offsets or sensor drifts.
Unauthorised changes of the set instrument parameters can be prevented by a user-definable code on different user levels.
All the configuring and programming can be done using the front control keys.
