Analog Devices 5B41-02 High Performance Plug-In Signal Conditioner Module

The Analog Devices 5B41-02 is a plug-in signal conditioner module that amplifies, protects, and filters analog input voltages for industrial process control and measurement systems. It delivers 1500 V rms continuous isolation between field and computer-side circuitry, withstands 240 V rms input overvoltage, and maintains ±0.05% calibrated accuracy with chopper-stabilized drift of ±1 µV/°C. The module generates 0 V to +5 V outputs across a 10 kHz bandwidth, suitable for rapidly changing signals in temperature, pressure, flow, and vibration monitoring applications.
