    cPCI/PXI Isolated Amplifier with Optional Bridge Conditioning

    体彩足球总进球 www.1m1n.com The Preston Scientific 8248AU is a single-width, 6U, CompactPCI/PXI module with 4 channels of Isolated Signal Conditioning feeding two buffered outputs. This single-module signal conditioner solution can be coupled with any data acquisition system, including analog-to-digital converter products from KineticSystems. Optional configurations support complete bridge signal conditioning.

    Two buffered outputs are provided with the 8248AU. One buffered output is a pre-filter output that is at the sensor input ground potential. The second buffered output is an isolated version of the input signal at chassis potential. This second output can be selected to be either pre-filter or post-filter.

    The secondary buffered output is isolated through the use of optical isolation. The input signal is digitized at a rate of 250 kHz by an analog-to-digital converter (ADC). An ADC is present for each channel to eliminate the multiplexing effects of a single ADC implementation. The converted data is then fed into an optical isolator for re-generation by a digital-to-analog converter.

    Each channel of the 8248AU isolated amplifier provides isolated inputs with operation up to ±300V common mode. Software selectable filter cutoff frequencies are programmed on a per-channel basis and include 20Hz, 200Hz, 500Hz, 1kHz, 2kHz, 5kHz, 25kHz, 50kHz and filter bypass (wide-band). Programmable gain settings of 1, 2, 5, 10, 20, 50,100, 200, 500, 1000, 2000, 5000 and 10000 are provided.

    The 8248AU bridge option supports 10 wire transducer connections. The bridge signal conditioning option adds shunt calibration, bridge balance, and excitation selection on a per channel basis. Each channel input is completely isolated from the other channel inputs, including excitation supplies, through extensive use of DC/DC converters. On-board bridge completion handles 120Ω, 350Ω or 1000Ω bridges in ¼, ½ and full configurations. The per-channel excitation sources are programmable from 0 to 10 volts in 4096 steps and contain alarm circuitry to monitor excitation supply health. Each channel can be programmed for either voltage or current excitation. Bridge offsets may be nulled using on-board 12-bit DACs to maximize the dynamic range of the instrument.
