Each potentiometer can be programmed to a different resistance value with 256 steps of adjustment per resistor. Three connection points per resistor allow direct wiring across the resistor and to the potentiometer wiper. Available with a USB or RS-232 interface, NCD digital potentiometer devices also include a XR expansion port, allowing relay control from the same device using external relay banks.
