Programmable Digital Potentiometer

Digital PotemtiometerOur Digital Potentiometer controllers offer our customers the capability of integrating programmable digital potentiometers into their next computer control application. Potentiometers are available in 10K, 50K, and 100K values. Each potentiometer output can be set to any of 256 possible output values. Each potentiometer may be controlled individually, or you may control all potentiometers simultaneously.


RS232 and USB Interfaces Available

Our entire line of digital potentiometers are expandable to 256 potentiometer output channels using additional UPOT16 expansion modules.  The RS-232 serial interface has a programmable baud rate up to 115.2K and the USB interface mounts as a Virtual COM Port under ANY Operating System, and is again controlled at 115.2K Baud.  The RS232 or USB Potentiometer versions have your choice of 8, 16 or 24 channels of programmable potentiometers with 3 contact points for each programmable resister.

Resistance Output

Please keep in mind; our POT series controllers offer a resistance output, and cannot provide a voltage output of any kind without additional electronics. The potentiometers are limited to applications that operate in the 0 to 5V range. Each potentiometer has a maximum current capacity of 1ma. Exceeding these rating will immediately damage the controller.
