National Instruments BNC-2140 DSA Signal Conditioning Accessory

Features
  • Interfaces (4) BNC Signal Inputs and (2) BNC Signal Outputs
  • Compatible with NI PCI-4451, NI PCI-4452, NI PCI-4551, and NI PCI-4552
  • Connects to Voltage Sources with Outputs of Less Than ±42.4 V
  • Each Input Channel has an Independent 4 mA Current Source
  • IEPE Signal Conditioning can be Manually Enabled or Disabled on a Per-Channel Basis
  • Each I/O Channel can be Manually Switched from Differential (DIFF) to Single-Ended (SE) Mode

Description

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.


Product Family: BNC-2140, BNC2140, BNC 2140, BNC-214O, BNC214O, BNC 214O

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
