PCI Express data acquisition card APCIe-3660

analogdigital

The PCI-Express analog and vibration measurement card APCIe-3660-4 has 4 SE/diff. (+/-) inputs with a sampling frequency of up to 4 MHz for simultaneous acquisition and 4 digital I/O, 24 V. 4 current sources for the direct connection of ICP™ sensors (integrated circuit piezoelectric) are available. The card is especially suited for noise- and vibration measurement in the harsh industrial environment Features Extended operating temperature range: -20 °C to +85 °C Analog inputs 4 SE or diff. (+/-) inputs (via SMB connector) 1 A/D converter per channel: Simultaneous acquisition at all analog inputs Sampling frequency: 125 kHz, 250 kHz, 500 kHz, 1 MHz, 2 MHz, 4 MHz Input range: ± 10 V, ± 1 V Coupling: AC, DC, GND (programmable for each channel) Overvoltage protection Optical isolation between analog channels and from the PC (1000 V) Anti-aliasing filters as integrated digital filters, cut-off frequency changes according to sampling frequency, automatic adjustment to Nyquist frequency Analog filters with fixed cut-off frequency (3 MHz) 1 current source per channel for IEPE sensor supply (4 mA to 26 V) 24 V trigger input (via SMB connector) Input modes Simple mode: Reads single analog value Cyclic mode (auto stop): Starts analog acquisition through software, stops acquisition when configured number of values has been reached, analog values are available in software buffer Cyclic mode (ring buffer): Starts analog acquisition through software, continuous acquisition until software stop, analog values are available in software buffer
