Signal conditioning components (scc) modules

National Instruments has announced new signal conditioning component (SCC) modules for frequency-to-voltage conversion, integrated circuit piezoelectric (ICP) accelerometers, and resistance temperature detectors (RTDs). The SCC-FV01 is a dual-channel frequency-to-voltage conversion module that accepts ?10 V signals up to 100 Hz. The output of this module scales linearly with the input frequency and can read 0 V for a DC input signal. The SCC-ICP01 single-channel module for active accelerometers accepts ?5 V signals and has a 19 kHz 3-pole Bessel low-pass filter for noise and anti-alias filtering. The module features a 4 mA current source to power ICP compatible sensors. The dual-channel SCC-RTD01 module accepts 2, 3, and 4-wire platinum RTDs and has a 1 mA excitation source to power RTDs. Both channels feature a gain of 25 and a 30 Hz low-pass filter to remove noise. NI also expanded the line of SCC-LP series modules to include the SCC-LP04, which has noise and anti-alias filtering for general inputs and provides a 1 kHz cut-off frequency. The SCC-LP series modules are two-channel fourth order butter worth low-pass filter modules with differential inputs that support ?10 V signals.
