Because of the improved reliability of the machine and the realization of miniaturization, so it is used in various fields.
PhotoMOS advantages
The biggest difference between hotoMOS and traditional mechanical relays is that PhotoMOS is a "photoelectric coupler" that does not open and close the contacts mechanically. For this reason, it has excellent characteristics in contact reliability, life, action sound, action speed, and size.
In addition, even the same photoelectric coupler, because of the use of different output components, also divided into many types. The features and uses of PhotoMOS are different, but because the output component uses a power type MOSFET, the conversion device is suitable for controlling tiny analog signals compared to the photothyristor and phototransistor methods.
