The 7B31 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 7B31 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 120 dB @ 50/60 Hz and a normal mode rejection (NMR) of 60 dB @ 50/60 Hz are provided. Rated to operate with a nominal +24 VDC supply, Model 7B31 is mix-and-match and hot-swappable with other 7B Series input modules, so it can be inserted or removed from any socket in the same backplane without disturbing system power.

The floating differential input of Model 7B31 is fully protected up to 120 V rms line voltage. A one-pole 3 Hz filter preconditions the input signal prior to amplification by a low drift input (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 two-pole low pass filter (-3 dB @ 3 Hz), 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 k minimum.
