National Instruments cFP-SG-140 Strain/Bridge Input Module
The cFP-SG-140 is a strain/bridge input module for Compact FieldPoint designed by National Instruments. The cFP-SG-140 is available under part number 777318-140. This module is used to measure full/half bridge strain gauges and is compatible with different bridge-based sensors. The NI cFP-SG-140 is a plug-and-play module, which means that the system can automatically detect modules. The cFP-SG-140 also features a built-in excitation mode, which supports different programmable excitation levels. To ensure precise and accurate measurements, the cFP-SG-140 can be calibrated.
The cFP-SG-140 strain/bridge input module has eight differential input terminals. The ADC resolution of the input terminal is 16 bits. A delta-sigma ADC is used in the cFP-SG-140. The impedance of the input terminals is 20 MΩ. The built-in excitation is user selectable and has different excitation voltages. The supported voltage levels are 2.5 V, 5 V, and 10 V. The NI cFP-SG-140 is a low-noise module with different noise filters. The user can select any filter depending upon the application requirement. The cFP-SG-140 features 15 Hz, 60 Hz, and 240 Hz filters. The range for the update time of all channels is 0.9 sec to 1.15 sec. Also, the device has a channel update rate of 1.11 to 0.87 Hz.
The NI cFP-SG-140 can withstand 2300 Vrms of transient voltage. The continuous isolation voltage is up to 250 Vrms. The adjacent channels of the module are not isolated. Status indication includes two green LEDs (POWER, READY) and one red OVERCURRENT LED.
The cFP-SG-140 weighs 3.7 oz and has recommended operating and storage temperature ranges of -40 to 70°C and -55 to 100°C, respectively; a non-condensing relative humidity range of 10 to 90%; and random and sinusoidal operating vibrations of 5 grms and 5 g, respectively, all at a frequency range of 10 to 500 Hz.

National Instruments cFP-SG-140 Frequently Asked Questions
Question: Does the NI cFP-SG-140 require periodic calibration or verification?
Answer: The Strain/Bridge Input Module should be calibrated periodically.
Question: What does it mean if the cFP-SG-140 has a flashing power LED and it’s not recognized in MAX?
Answer: A flashing POWER LED usually indicates a communication or initialization problem. First reseat the module, verify backplane power, confirm the bank controller is detected in MAX, and check firmware compatibility before concluding the module needs repair.
Question: Is the cFP-SG-140 considered a low-noise input device?
Answer: The Strain/Bridge Input Module is a low-noise input module.
