Introducing the World's smallest fully functional isolated analog signal conditioner, the Sensorlex 8B range.
The 8B43 can interface to transducers that will operate on a 10V excitation voltage and up to 30mA of excitation current.
Signal filtering is accomplished with a 5-pole filter optimised for time and frequency response which provides 100dB per decade of normal-mode rejection above 1kHz. One pole of this filter is on the field side of the isolation barrier for anti-aliasing and the other four are on the system side.
A special input circuit on the 8B43 modules provides protection against accidental connection of power-line voltages up to 240V AC. Clamp circuits on the I/O and power terminals protect against harmful transients.
Isolation is provided by transformer coupling to suppress transmission of common mode spikes or surges. The module is powered from +5V DC, ±5%.
The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise.
