• For POSIROT® and POSITILT® position sensors with

analogoutputs:

Voltage 0 ... 10 V; 0.5 ... 10V; 0.5 ... 4.5 V

Current 4 ... 20 mA

Voltage divider

• Integrated sensor supply (24 V DC)

• 6-digit LED display

• RS-232 interface

• Optional 4 comparator outputs

• Easy programming

PRODIS-ADC is designed for use with analog position sensors to display angles and

displacements. A high resolution A/D converter processes signals from sensors with voltage

output 0 ... 10 V, current output 0/4 ... 0 mA or voltage divider (potentiometer).

The meter is programmable to display values within preset start/end range or values in units

as inches, mm or degrees. A tare function or programming lock can be activated with two

control terminals.

Sensor excitation is supplied by the meter. With four membrane keys all parameters can be

programmed for the special applications. Optional comparator functions with 4 NPN open-

collector outputs are available, additional of them have relay output.
