Campbell Scientific, Inc. Filtered Analog Input Module CR9052DC

This high-performance anti-alias filter module can be used in either the CR9000X-series or CR9000-series Measurement and Control Systems. The CR9052DC module measures accelerometers, strain gages, and microphones. The CR9052DC includes 6 anti-aliased analog measurement channels with differential input ranges from ±20 mV to ±5 V. Each of the 6 channels has its own programmable-gain instrumentation amplifier, pre-sampling analog filter, and sigma-delta analog-to-digital converter. An on-board digital signal processor provides real-time, programmable anti-alias filtering and down-sampling (decimation) before passing the results to the datalogger’s main processor.
