Data coupling electric energy with isolation performance

Published:2011/8/10 3:58:00 Author:Nicole | Keyword: data, electric energy, isolation performance | From:SeekIC

The length of optical fiber or polyrod decides the voltage isolated extent between digital or analog signal input terminal and FPT100 photoelectric detector. This photoelectric detector drives 9720 operation amplifier. The output current of operation amplifier is 100mA, it can drive cable, relay or loudspeaker. LED is MV50, its capacity can reach 200mA. If there is no light, the output of operation amplifier is 0. When it is transporting analog data, it shouldadpot PWM.
