12.5
GN440 and GN441 Universal amplifier input cards
This unique, high
-
end input card with an 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
channel samples at a maximum speed of 200 kS/s or 1 MS/s with
a 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 a
common mode voltage of up to 250 V RMS.
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 one ampere in a
safe, isolated and fused manner, without the need for external
shunt resistors.
