The National Instruments BNC-2140 DSA Signal Conditioning Accessory interfaces four BNC signal inputs and two BNC signal outputs directly to National Instruments DSA products including the NI PCI-4451, NI PCI-4452, NI PCI-4551, and NI PCI-4552. The BNC-2140 connects to integrated circuit piezoelectric, also known as Integral Electronic Piezoelectric (IEPE), accelerometers, microphone preamplifiers, and other voltage sources with outputs of less than ±42.4 V.
Each input channel has an independent 4 mA current source suitable for use with IEPE-type accelerometers and microphone preamplifiers. You can manually enable or disable the IEPE signal conditioning on a per-channel basis. With IEPE disabled, a BNC-214 0 input channel acts as a direct voltage input. You can manually switch each input channel and each output channel from differential (DIFF) to single-ended (SE) mode. In SE mode, the BNC shell is connected to
analog ground through a 50 Ω resistor.
The BNC-2140 receives power for IEPE signal conditioning from the DSA plug-in device through the 68-pin high-density connector. A green LED indicates when the IEPE circuitry is powered on. When IEPE signal conditioning is not required, you can manually power off the circuits.
The NI BNC-2140 DSA Signal Conditioning Accessory Replacement Card may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
