The GEN DAQ Basic/IEPE ISO 2 MS/s Input Card is a general
purpose signal conditioner for use with voltage inputs, externally
conditioned signals or probes and current clamps. This card also
supports IEPE transducers and TEDS Class 1 for easy setup of
the acquisition channels.
The amplifier provides voltage inputs from
±
10 mV to
±
50 V. The
model uses an isolated metal BNC for each channel.
Optimum anti
-
alias protection is achieved by the 7
-
pole analog
anti
-
alias filter combined with a fixed 2 MS/s sampling Analog
-
to
-
Digital
converter. For all sample rates the digital anti
-
alias filter allows for a large range
of high order filter characteristics with precise phase match and noise
-
free
digital output.
For true real
-
time analysis, the card offers real
-
time cycle or timer based
calculations. Automatic zero crossing detection allows for asynchronous true
RMS, mean and other calculations that can be used to trigger the recording.
If supported by the selected mainframe, the GEN DAQ series input card offers
16 digital input events, two digital output events and two Timer/Counter
channels.
Using voltage probes a single
-
ended 600 V RMS CAT III / 1000 V CAT II or a
differential 1000 V RMS CAT III (1000 V RMS common mode) measurement
range is created. The use of current clamps allow for direct current
measurements.
