Digital Potentiometers

A digital potentiometer is a panel device with a numeric display that converts a value set with the buttons on its front panel into an analog output signal such as 0-10 V or 4-20 mA. It is used instead of a mechanical potentiometer to give a speed or setpoint value to frequency inverters and other drives with an analog reference input. This category includes the Enda EDP, GEMO DP102 and Tense PTM models; 72 × 72 mm and 77 × 35 mm housings, 230 V AC or 10-30 V DC / 8-24 V AC supply and types with RS485 Modbus communication are available. Select the model by the output signal the drive expects, supply voltage, panel dimension and whether the value also needs to be set over Modbus. Some models have lower and upper limits, a ramp function and the ability to switch the output with digital inputs. A panel-mount digital potentiometer is not the digital potentiometer chip used on electronic boards; it is a powered industrial device with an analog output that is mounted in a panel.

How to choose Digital Potentiometers

A digital potentiometer is a panel device with a numeric display that converts a value set with the buttons on its front panel into an analog output signal such as 0-10 V or 4-20 mA. It is used instead of a mechanical potentiometer to give a speed or setpoint value to frequency inverters and other drives with an analog reference input.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
