prodis® Digital Process Displays PD-ADC Process Display for analog sensors Voltage (e.g. 0 … 10 V) Current(e.g. 4 … 20 mA) Voltage divider (Potentiometer) Integrated sensor power supply prodis ®-ADC is designed for use with analog position sensors to display angles and dis-placements. A highresolution A/D converter processes signals from sensors with voltage or current output. 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 output are available, additional 2 of them have re
