The 5B30 and 5B31 are single-channel signal conditioning
modules that amplify, protect, filter and isolate analog input
The 5B30 and 5B31 protect the computer side from damage due
to field-side over voltage faults. All models withstand 240V rms
at their input terminals without damage thereby shielding
computer side circuitry from field-side over voltage conditions.
In addition, 5B30 and 5B31 Series modules are mix-and-match
and hot swappable, so can be inserted or removed from any
socket in the same backplane without disrupting system power.
A chopper-stabilized input amplifier provides low drift and
stable gain. At the amplifier input, a stable, laser-trimmed zero-
scale input voltage is subtracted from the input signal to set the
zero scale value. For user convenience, the zero can be
optionally factory-set to meet custom needs. This allows
suppression of a zero-scale input value many times larger that
the total span for precise expanded-scale measurements.
Internal multi-pole low-pass filtering with a four-Hz cutoff (-
3dB) enhances normal-mode (noise on signal) and common-
5B30 / 5B31
mode (nosie on signal return) rejection at 50/60 Hz, enabling
accurate measurement of small signals in high electrical noise.
Signal isolation by transformer coupling uses a proprietary
modulation technique for linear, stable and reliable
performance. The differential input circuit on the field side is
fully floating, eliminating the need for any input grounding. A
demodulator on the computer side of the signal transformer
recovers the original signal, which is then filtered and buffered
to provide a low-noise, low-impedance output signal. The
output common must be kept within +3 V of power common.
A series output switch eliminates the need for external
multiplexing in many applications. The switch is turned on by
an active-low enable input. If the switch is to be on at all times,
the enable-input should be grounded to power common as it is
on the 5B01 and 5B08 backplanes.
