- Replicate the behavior of resistance-based devices
- 16-bit modules provide a range of 16 kiloohm with a resolution of 0.25 ohm
- 8-bit modules provide a range of 255 ohm with a resolution of 1 ohm
- Each module is software configurable as an RTD simulator, potentiometer, or resistive load
Programmable resistors are test modules that replicate the behavior of resistance-based inputs and outputs such as potentiometers, resistance temperature detectors (RTDs), voltage dividers, and bridge elements. NI 272x programmable resistor modules programmatically control a series of relays to vary the resistance across each channel of an I/O connector.
