The IsoCap-V1HP module is designed to isolate and scale low voltages found in industrial enviroments. The end result connects to any data acquisition system.
The IsoCap-V1HP's signal input has surge protection circuitry, the operation amplifier converts the input signal to ±10V range, The modulator converts this analog input signal into a digital bitstream that is transferred across the isolation barrier. On the low-side, the received bitstream is processed by a fourth-order analog filter that outputs a differential signal. The operation amplifier with an anti-aliasing filter outputs ± 10V. The following diagram depicts the signal processing above.
- The isolation barrier of every device is tested with a 5 second partial discharge of 1800V for 5 seconds, with a detection threshold of 150pC.
- Withstanding common mode surge voltage is 2 seconds half sinewave.
- Withstanding differential mode surge voltage is 4 seconds half sinewave.
