Abstract

Telah dibuat rangkaian transfer data arus dengan men gunakan serat optik. Sistem peralatan ini mempunyai rentang nilai arus antara 10 - 10-5 Ampere. Rangkaian transfer data arus dimulai dari rangkaian pengubah .arus ke tegangan yang menggunakan IC LM 741. Tegangan keluaran dari pengubah arus ke tegangan diubah ke frekuensi menggunakan IC AD 650. Frekuensi keluaran pada V/F converter diubah menjadi pulsa cahaya oleh transmitter kemudian ditransmisikan melalui serat optik. Pulsa cahaya akan diubah menjadi frekuensi oleh receiver. Rangkaian F/V converter akan mengubah kembali frekuensi .menjadi tegangan. Dari hasil pegujian keseluruhan rangkaian menunjukkan hubungan yang tinier antara anus dan tegangan, antara tegangan dan frekuensi, antara frekuensi dan frekuensi, dan antara frekuensi. dan tegangan. Tegangan. keluaran dari percobaan menga1ami pelemahan sebesar (0,09648 ± 0,00386) terhadap tegangan keluaran dari perhitungan. Data transfer circuit of current has been made by using optic fiber. This .circuit system has current range of scale from 104 to le Ampere. Data transfer circuit was . start from I/Vconverter circuit by IC LAI 741. Output voltage of 1/1/ converter was changed to frequency by IC AD .650. Output frequency at V/F converter has been changed to light pulse by transmitter and then transmitted via optic fiber. Receiver will change light pulse to frequency. The F/V converter circuit will change frequency to voltage again. From test at all circuit, we obtained linear relation between current and voltage, between voltage and frequency, between frequency and frequency, and between frequency and voltage. Output voltage from experiment has attenuation of output voltage from equation by an amount (0, 09648 ± 0,00386. ).
