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.
