Description
The National Instruments SCXI-1140 Differential Amplifier Module, with a part number 776572-40, is a robust device that features 8 channels for versatile data acquisition needs.
It is fully compatible with several software and hardware including NI-DAQmx measurement services software, NB Series data acquisition boards, and also supports LabVIEW for Macintosh alongside NI-DAQ software for Macintosh.
The module provides an impressive output slew rate of 15 V/μsec, ensuring rapid signal changes are captured with high fidelity, and maintains a low input noise spectral density of 12 nV/√Hz, which is essential for accurate measurements.
Furthermore, the output noise spectral density is limited to a low 75 nV/√Hz, which further enhances the precision of the readings. The module can handle a maximum output voltage of ±10 V, providing ample headroom for a variety of signal levels.
Included within the module are dedicated jumpers (W11, W13, and W14) that facilitate effective communication between the SCXIbus and the data acquisition board.
It supports multiple scanning modes such as single module parallel and multiplexed scanning, giving users the flexibility to choose the best mode for their application. The module also features a four-byte, read-only ID register, and a 32-bit, write-only configuration register for system setup.
Each input terminal is safeguarded by a 1 kΩ resistor in series, providing robust input protection against external electrical noise and potential damage from signal spikes.
Despite the End of Life Status having been announced by National Instruments, this module remains available for purchase and repairs through Apex Waves, ensuring continued support for existing systems.
