National Instruments 777459-37 Strain/Bridge Module 

National Instruments part number 777459-37 is an identifying part number for the SSC-SG24, a Strain/Bridge Module with 1.6kHz Filtering and 2 Channel Load Cell Inputs. The input characteristics of the device include two differential channels with an input signal range of ±100 mV and an output signal range of ±10 V. The device features a gain of 100 and provides overvoltage protection up to ±42 VDC, both when powered on and off. It is equipped with a single-pole buffered RC filter that offers a bandwidth of 1.6 kHz. Additionally, the device provides an excitation voltage of 10 V with a precision of ±0.05%. 

The part number 777459-37 uses four active strain gauge elements configured in a full-bridge arrangement. The NI software supports three variations of this full-bridge configuration. Configurations I and II of the full-bridge setup are designed to measure bending strain exclusively. Conversely, configuration III is tailored to measure axial strain. Additionally, this module can perform shunt calibration, which helps users correct any gain discrepancies. It has exceptionally low input noise, with an RMS value of just 1 µV. It provides an analog input bandwidth of 1.6 kHz through a single-pole RC filter. 

The module's common mode rejection ratio is at least 110 dB. Additionally, it features one excitation channel with a current drive capability of 42 mA². The 777459-37 module includes two differential input channels, each protected against overvoltage up to ±42 VDC, regardless of the power state. Each channel has dedicated circuitry for offset nulling, a built-in excitation circuit, and an instrumentation amplifier.
