The Universal ISO 500 kS/s Input
Card supports quarter, half and full
bridges with constant voltage
excitation. A built
-
in shunt offers the
possibility of positive or negative
shunting of the Wheatstone bridge.
For quarter bridge support the card has a 350 Ω and 120 Ω built
-
in completion
resistor.
In IEPE mode the card supports open and shorted wire detection.
Thermocouples, piezoelectric, RTD and 4 to 20 mA sensors are all directly
supported. Every mode supports either IEEE 1451.4 TEDS class 1, 2 or 3.
(Class 3 IEEE approval pending).
Optimum anti
-
alias protection is achieved by an anti
-
alias filter built
-
in the fixed
500 kS/s sampling Sigma Delta ADC.
At lower sample rates the digital anti
-
alias filters allow for a large range of high
order filter characteristics with precise phase match and noise
-
free digital
output.
Besides the instantaneous values, the real
-
time cycle detection allows for cycle
based real
-
time calculations like TrueRMS or PeakToPeak. The real
-
time
formula database calculators option offers math routines to solve almost any
real
-
time mathematical challenge. Real
-
time calculated results can be used to
trigger the recording. Every cycle based result from the real
-
time formula
database can be transferred in real
-
time to the EtherCAT
®
output card option
of the mainframe.
