6 / 17 page Portable, Modular Signal Conditioning Modules 6 BUY ONLINE at ni.com or CALL 800 813 3693 (U.S.) NI SCC-SG Series Strain Gage Input/Excitation The National Instruments SCC-SG Series consists of dual-channel strain gage modules for conditioning quarter, half, and full-bridge strain gages and a calibration module. Each module is designed for a specific type of bridge configuration. Each channel of an NI SCC-SG module (except SCC-SG11) includes an instrumentation amplifier, a 1.6 kHz lowpass filter, and a potentiometer for bridge-offset nulling. Each SCC-SG0x module also includes a single 2.5 V excitation source. The SCC-SG24 has a 10 V excitation source for load cells and pressure sensors. The SCC-SG11 is a dual-channel shunt calibration module for use with the SCC-SG0x and SCC-SG24 modules. Each channel includes two terminals for wiring a switched 301 kΩ, 1 percent, 1⁄4 W resistor across any two points of your bridge. You enable shunt calibration for both channels of a module by writing a logic high to the digital line controlling the SCC-SG11. You disable shunt calibration by writing a logic low to the same digital line. When you install an SCC-SG module in the SC-2345, the carrier routes the strain gage signals to two input channels of the multifunction DAQ device, channels x and x+8, where x is 0 through 7.
