Expansion Board Digital Multichannel Potentiometer

The Digital Multichannel Potentiometer Expansion Board extends the functionality of the µLC Test System by seamless integration into an existing device. It offers four independently configurable, galvanically isolated digital potentiometers with a wide range of resistance and excellent accuracy. All four channels feature individual protection by an automatic overcurrent shutdown with automatic retry.
