Description
Specification
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 ... 20 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 2 of them have relay output.
