WF 2144 – USB Programmable Resistor Module
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.

Support & FAQ
Visit our knowledge base on our Support Portal if you don’t find any answers to your questions here.
What kind of connector are used for the module?
The WF 2144 and uses a 10-Pos Plug. You should connect a terminal block for 10-Pos Plug to the module. This terminal block is included together with the module when shipped from WireFlow.
How is the WF 2144 Programmable Resistor Module designed?
The module uses an array of real resistors switched with solid state relays to the desired resistance.
