Digital signal conditioner 4021

opto-isolatedamplifierspeed sensor

The Model 4021 set up as a digital opto-isolated noise canceling amplifier prevents ground loops and interrupts any galvanic signals riding on a magnetic speed sensor output signal. Optimizes the perfomance of SPECTEC's unique noise canceling magnetic sensors as well as providing superior performance with standard VR sensors. The power supply input covers 6 to 36 Vdc regulated with no selection needed. All inputs and outputs are fully protected against short circuits to supply or ground and reverse polarity supply leads. The circuitry is protected against higher voltages to 200 Vpp.
