APCIe-3660 – DAQ PCIe Card – Vibration measurement
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
- 4-lane PCI Express board
- 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
- 24-bit resolution (sampling frequencies of 2 MHz and 4 MHz: 23-bit resolution)
- 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)
Digital I/O
- 4 digital inputs, 24 V, optically isolated
- 4 dig. outputs, 24 V, optically isolated
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
- Gate logic: Each digital input controls the acquisition of the corresponding analog input (digital input 0 -> analog input 0, digital input 1 -> analog input 1, etc.) via rising edges (from 0 to 1: acquisition is started) and falling edges (from 1 to 0: acquisition is stopped). The data of the respective analog input is stored in a temporary buffer on the board before it is transferred to the PC.
