... NPN phototransistor. Signal information, including a DC level, can be transmitted by the drive while main- taining a high degree of electrical isolation between input and output. The ILD1 ILQ1 are espe- cially designed for driving medium-speed logic and can be used to eliminate troublesome ground loop and noise problems. Also these couplers can be used to replace relays and transformers in many digital interface applications such as CTR modulation ...
