Description
The NI SCC-SG02 Strain Gage Module, with part number 777459-14, is designed for Quarter-Bridge configurations and features a resistance of 350 Ω. It has two differential channels that are equipped with an integrated 1.6 kHz lowpass filter to ensure accurate measurements in noisy environments.
Each channel includes an integrated 2.5 V excitation source and one 350 Ω quarter-bridge completion resistor, with the resistors being socketed for easy replacement when necessary. The module can process analog signals ranging from -100 to +100 mV and has overvoltage protection on each channel.
When powered on, the SCC-SG02 operates with an input impedance of 10 MΩ and an input noise level of 1 µVrms at a bandwidth of 1.6 kHz. It consumes 143 mW of analog power and draws 42 mA of current at +5 VDC. Despite its obsolete status, the module is still available for purchase and repairs.
