The Analog Devices 5B30/5B31 Millivolt and Voltage Inputs are single-channel signal conditioning modules that amplify, protect, filter and isolate analog input voltages.

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 zeroscale 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.
