The MSXB 067 Signal Conditioning Expansion Board provides analog signal conditioning for strain gauges, load cells, RTDs, potentiometers, and other resistive sensors. MSXB 067 provides a flexible interface for quarter-bridge, half-bridge, and full-bridge sensors, with two to six wires for each sensor, with or without voltage sense feedback. A small daughterboard supports user-supplied bridge completion resistors.
Each MSXB 067 has
- 8 differential inputs
- jumper-selectable simultaneous sampling
- jumper-selectable gains of
- 20, 40, 100, 200, 500, and 1000 (for strain gauges, load cells, etc.), or
- 1, 2, 5, 10, 25, and 50 (for RTDs, potentiometers, etc.)
- jumper-selectable differential voltage excitation of 1.024 V, 2.048 V, and 3.072 V
- fourth-order anti-alias filters
- cutoff frequencies from 100 Hz to 50 kHz
Each MSXB 067 supports
- 8 bridge sensors per board
- one 8-pin mini-DIN connector for each sensor
- force/sense feedback
- sense voltage measurement
Signal Conditioning Expansion Boards are used in multichannel spectral analysis and other applications that require simultaneous acquisition of several channels. These boards eliminate the phase error introduced by sequential sampling.
Sampling introduces alias errors when the input signals contain energy at frequencies above half of the sampling rate. In addition to simultaneous sampling, the MSXB 067 board has fourth-order lowpass filters to eliminate the aliasing errors inherent in sampling under these conditions.
The MSXB 067 Signal Conditioning Expansion Board has 8 differential input channels and 16 differential outputs to a DAP board: 8 for signals and 8 to sense the excitation voltage. Each channel on MSXB 067 has a four-pole analog lowpass filter on a daughterboard; the daughterboard can be changed to adjust the cutoff frequency.
Each DAP board has an onboard processor with built-in filtering commands. By applying onboard digital filters to the output data from MSXB 067, it is possible to construct a wide range of filter responses, including very sharp lowpass filters.
Channel Architecture allows up to 15 MSXB 067 boards to connect to a single DAP board for up to 120 channels of resistive sensor input.
The MSXB 067 provides signal conditioning expansion for Analog Backplane systems. The Signal Conditioning Expansion Board is compatible with Industrial Enclosures and the MSXB 030-01 and MSXB 031-01 Analog Backplanes. Each MSXB 067 takes two slots in an enclosure.
