The NI SCC-LP03 is a dual-channel signal conditioning module for the National Instruments SCC carrier system. It provides fourth-order Butterworth lowpass filtering at 150 Hz cutoff to attenuate high-frequency noise and improve measurement integrity in data acquisition systems. Each channel accepts ±10 V differential input signals, which are attenuated by a factor of two before filtering, then output at ±5 V levels compatible with SCC carrier inputs.
Technical Specifications
• Filter Architecture: Fourth-order Butterworth lowpass filter per channel
• Channels: 2 differential input channels
• Cutoff Frequency: 150 Hz
• Input Range: ±10 V differential
• Output Range: ±5 V
• Input Attenuation: 2× (factor of two) by differential amplifier preceding filter stage
– Key Features
• Low-profile SCC module form factor for compact integration
• Dual independent differential channels for parallel filtering
• Pre-filter attenuation stage reduces input signal amplitude prior to filter processing
• Output signals directly interface with SCC carrier input stages
– Typical Applications
• Noise rejection in precision analog data acquisition
• Anti-aliasing filtering for multifunction DAQ systems
• Sensor signal conditioning where high-frequency rejection is critical
• Industrial measurement systems requiring stringent signal integrity
– Compatibility & Integration
• SCC Carriers: Compatible with NI SCC shielded carrier systems (SC-2345 Series and equivalent)
• DAQ Devices: Supports all E Series and Basic multifunction DAQ devices, DAQCards, and DAQPads
• Software: Operates under NI-DAQmx driver with ANSI C interface support
• Power Consumption: DAQCard/DAQPad configurations require <800 mW total module power (490 mW analog maximum); PCI, PXI, M Series, and E Series require <4.55 W total (1.74 W analog maximum)
