National instruments has announcedlaunched 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 expandedincreased the line of scc-lp series modules to include the scc-lp04, which has noise and anti-alias filtering for general inputs and providesdelivers 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.
