7B40

GENERAL DESCRIPTION

implement transformer isolation (1500 V rms input-to-output

The 7B40 is a single-channel signal conditioning module that

interfaces, amplifies and filters unipolar and bipolar millivolt

and voltage inputs and provides a protected precision output of

either +1 V to +5 V or 0 V to +10 V. Model 7B40 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 Hz are provided. Rated to

operate with a nominal +24 VDC supply, Model 7B40 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.

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 four-pole output filter and subsequent buffer

ensures that a low noise, low impedance (<1Ω) signal is

available at the output to drive loads of 2 kΩ minimum.

The floating differential input of Model 7B40 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
