The WF 2144 is a USB 2.0 compatible 4-channel, 16 bit, programmable resistor module.
Each channel is galvanically isolated, making it ideal for sensor simulation.
The 16 bit resolution is non-linear with finer steps at lower resistance values.
It could, for example, be used to emulate a PT100 sensor with a range of 40–180Ω/-150–+200°C with a resolution of 0.1°C.
An open API using the Modbus standard with Python and LabVIEW drivers makes it compatible with most computer architectures and operating systems.
