The 41-660 and 41-661 are high voltage attenuators
designed to reduce the high output voltages commonly
generated by some types of sensors. This is in order to
produce manageable signal levels that can be acquired
by typical data acquisition devices in a PXI system.
The 41-660 provides 10 single ended attenuator
channels while the 41-661 provides 5 differential
attenuator channels. The attenuated signals are
provided on 50Ωoutputs to ensure they can drive
simple data acquisition systems with no significant loss
of signal level. Each model provides attenuation factors
of 10 to 160, permitting a 600V peak signal to be
attenuated to less than 4 Volts.
The 41-661 attenuates both the common mode and
differential signal equally to ensure the signal cannot
overload the data acquisition system and provides a
single ended output from a difference amplifier.
Attenuation values are controlled by high quality
instrument grade relays to ensure long service life. All
active devices are fully protected against the application
of over-voltages or short circuit loads.
