Opticalcoupler equipment isolation

Opticalcoupler equipment isolation is isolated by an opticalcoupler equipment. The structure of the opticalcoupler equipment is equivalent to packaging the LED and the photodiode. The LED converts the input electrical signal into an optical signal that is transmitted to the photosensitive tube for conversion to an electrical signal output, since there is no direct electrical connection, such

Both the signal is transmitted and the signal is isolated. As long as the quality of the opticalcoupler equipment is good, the circuit parameters are designed reasonably, and general faults are rare. If an abnormality occurs in the system, the potential difference between the input and output exceeds the voltage that the opticalcoupler equipment can withstand, causing it to be damaged by breakdown.

It can be thought of as a light-emitting diode and a photodiode or triode packaged together. Complete electrical isolation of the signal is possible. Widely used in signal acquisition systems.

The opticalcoupler equipment is a device that energizes the light emitting diode and the photodiode receives light. The benefits of input and output are isolated, just like a transformer. 6N137 and 6N138 are opticalcoupler equipment 8-pin ICs. The disadvantage of the light-isolator is that the size is too large.
