Model 6129, 8-Channel AC/DC-Coupled/IEPE Amplifier-Filter-Analog Output

Features

  • AC or DC coupled inputs
  • 2 to 20 mA current excitation
  • Gains 1 to 5,000 with 0.05% accuracy
  • 4, 6 or 8-pole, low-pass filter
  • 100 kHz signal bandwidth
  • Buffered ±10 Volt analog output

Description

The 6129 input module has eight channels each providing excitation for IEPE transducers, programmable AC or DC-coupled differential instrumentation amplifier and low-pass filter. Each channel has a buffered analog output that can be selected for wideband or filtered response.

Using amplifier-per-channel architecture offers the highest accuracy and completely eliminates crosstalk between channels. It may be used to condition signals from piezoelectric transducers with built-in or inline charge amplifiers and other AC or DC voltage measurements. Input attenuation and current inputs, including 4-20 mA current loop, are available.

An adjustable 2-20 mA current source with 24 Volt compliance is provided for powering IEPE transducers. Gain is programmable from 1 to 5,000 providing ±2 mV to ±10 Volts full scale input sensitivity. Zero and gain calibrations are automatic.

Bandwidth is DC, 1 Hz when AC coupled, to 100 kHz. The low-pass filter may be employed to minimize alias errors for data sampling. A plug-in resistor module establishes the desired frequency. Filter frequency may be specified at the time of ordering. Frequency modules are available from 250 Hz to 50 kHz.
