Application field of high-speed optocoupler
A. It can be used for PLC high-speed counter, servo motor control, rotary encoder control, grating ruler output, PLC and single-chip microcomputer pulse signal conversion; Anti interference processing of PLC and servo motor control system; Mutual conversion of various standard and non-standard pulse signals; Arbitrary waveform (sine wave, triangle wave, irregular waveform) to square wave pulse signal, etc.
B. In the switching circuit, it is often required to have a good electrical isolation between the control circuit and the switch, which is difficult to achieve for the general electronic switch, but it is easy to achieve with it.
C. It can be used in bistable output circuit. Because LED can be connected into two emitter circuits in series, the problem of output and load isolation can be effectively solved.
D. The logic circuits formed by them are more reliable because their anti-interference performance and isolation performance are better than those of transistors.
E. It can be used in digital circuits to amplify pulse signals.
F. It is used in high-voltage control, replacing transformer, replacing contact relay and A/D circuit.
G. It can be used in bistable output circuit. Because LED can be connected into two emitter circuits in series, the problem of output and load isolation can be effectively solved.
H. It is used in linear circuit, with high linearity and excellent ground electrical isolation performance.
