WF 3144 – Programmable Resistor Module
The WF 3144 is a 4-channel, 16-bit, Programmable Resistor Module for Compact RIO.
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.

Support & FAQ
Visit our knowledge base on our Support Portal if you don’t find any answers to your questions here.
Can I use ScanEngine for the module?
ScanEngine access is not directly accessible for Third-Party modules, but it is quite easy to mix WireFlow C Series modules with other NI modules in a system and still access the NI modules in Scan Mode. Please see application note AB0005-056 AN4 Mixing WF and NI modules for a step-by-step guide how to do this.
What kind of connector are used for the module?
The WF 3144 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 many FPGA resources does a C series module consume?
The FPGA usage of a specific software and hardware combination is affected by multiple factors such as; FPGA type and size, compilation options, the random starting point for FPGA code placement etc.
Hence, it is impossible to derive an exact figure that defines the FPGA usage of a specific C series module. For customers that are uncertain on whether their application will fit on a specific FPGA with a WireFlow C series module it is recommended to make a test-build. Note that no hardware is needed to make a test build. For more details, please see AB0005-104 AN16 FPGA Resource Usage for WF C Series modules.
Is the WF 3144 module compatible with cDAQ-systems from National Instrument?
No it is not. At the moment only the WF 3132 module works on both CompactDAQ and CompactRIO systems. The WF 3144 is for time being only compatible with the CompactRIO systems, including the expansions chassis for Ethernet, EtherCAT, R Series and MXI-Express. However, National Instruments has released a CompactRIO series that supports NI-DAQmx, called NI-904x (you can find them HERE). On these chassis you can use all of our C Series modules.

How is the WF 3144 Programmable Resistor Module designed?
The module uses an array of real resistors switched with solid state relays to the desired resistance.
