GN440 and GN441 Universal amplifier input cards
This unique, high-end, input card
with ultra-fast amplifier serves a
variety of needs; from differential
and/or isolated measurements to
IEPE-based vibration or shunt-
based current measurements.
The universal amplifier input card
has four input channels, each
sampling at 200 kS/s or 1 MS/s
maximum with 16 bit resolution. The
bandwidth is 500 kHz and a
selection of time or frequency
domain optimized filters is available
to eliminate noise if needed. The
voltage range for a channel can be
set from ±10 mV to ±100 V, making
the card adaptable to nearly every
application. True optical isolation
allows for measurements with up to
250 V RMS common mode voltage.
The on-board differential input
amplifiers eliminate noise picked up
in the device under test or the
measurement leads. Each amplifier
typically offers a high CMRR of
80dB. By switching to "IEPE mode",
the amplifiers supports any type of
constant current supplied vibration
and acceleration sensors. In
"Current mode", the built-in shunt can be used to measure up to 1 ampere in a
safe, isolated and fused manner, without the need of external shunt resistors.
