IEP-CON / IEP-DAQ / CONFIGURATION INQUIRY
IEPE Signal Conditioners & USB / Ethernet DAQ
From constant-current excitation to usable data.
A conditioner powers the IEPE electronics and separates the dynamic signal from its DC bias. A DAQ digitizes that signal. When using an external conditioner, disable input IEPE excitation and confirm the receiving device accepts the conditioner output.

FIRST, DEFINE THE OPERATING WINDOW
Sensitivity, interface and acquisition requirements
These are request profiles. Confirm the selected model’s datasheet before ordering; the listed targets do not describe one universal configuration.
| Conditioner channel requests | 1 / 2 / 4 / 8 |
|---|---|
| Excitation request | 4 mA / 24 V nominal; compliance must be specified |
| Analog output request | AC coupled; up to ±10 V only if confirmed |
| DAQ request profile | 4 / 8 channels; 24 bit; up to 102.4 kS/s per channel |
| Integration request | USB / Ethernet; FFT software and export format review |
Match the measurement to the test structure
Ordinary oscilloscopes: check AC input voltage and ground reference. Synchronous modal acquisition: confirm sample rate per channel, anti-alias filters and phase matching. PLC integration: use only suitable dynamic analog inputs with adequate bandwidth.
Review an existing sensor model →Documents to review before release
NI-9234 is a comparison reference: its official specification lists 2 mA excitation, ±5 V input and up to 51.2 kS/s per channel. IEP-DAQ targets are not a claim of NI hardware, software or driver equivalence.
Ask for available calibration method, traceability, frequency points and uncertainty. TEDS memory does not replace a current calibration record.
Cable, mounting and excitation belong in the same RFQ
Specify cable connector and pinout before selecting a cable. Magnetic mounts can reduce usable high-frequency response; holding force depends on surface and pull direction. Verify stud thread, seating surface, insulation and mounting torque. For a triaxial sensor, reserve three inputs.
Can I reuse an existing ICP® acquisition system?
Often, after checking current, compliance voltage, bias, signal headroom, coupling, connector and TEDS support. A matching sensitivity or connector is only part of the review.
Are price, stock and calibration included?
Request a configuration-specific quotation. Price, shipping date, accessory fit and calibration scope are confirmed in that quotation.
