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

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
