7B41 pdf
The 7B41 is a single-channel signal conditioning module that
interfaces, amplifies and filters unipolar and bipolar voltage
inputs and provides a protected precision output of either +1 V
to +5 V or 0 V to +10 V. Model 7B41 features a nonlinearity of
+0.02% maximum and an accuracy of +0.1% maximum
(+0.01% typical). To accurately measure low level signals in
electrically noisy environments, 1500 V rms of galvanic
transformer-based isolation with a common mode rejection
(CMR) of 110 dB @ 50/60 Hz and a normal mode rejection
(NMR) of 100 dB @ 50/60 are provided. Rated to operate with
nominal +24 VDC supply, Model 7B41 is mix-and-match and
hot-swappable with other 7B Series input modules, so it an be
inserted or removed from any socket in the same backplane
without disturbing system power.
The floating differential input of Model 7B41 is fully protected
up to 240 V rms line voltage. A one-pole 10 KHz filter
preconditions the input signal prior to amplification by a low
drift input amplifier. Amplitude modulation is used to
implement transformer isolation (1500 V rms input-to-output
and power). Isolated front-end circuitry power is supplied by a
DC/DC converter. The output section contains a four pole low
pass filter (-3 dB @ 10KHz), a buffer amplifier and a power
oscillator. The two-pole output filter and subsequent buffer
ensures that a low noise, low impedance (<1) signal is
available at the output to drive loads of 2 kminimum.
