Talk about optocoupler relay_solid state relay mos output

Talk about optocoupler relay Optocoupler relay is a type of solid state relay. The English name isSolid State Optronics Relay. Generally, relays are mechanical contacts, which rely on current flowing through the coil to turn into magnetic magnets to attract the contacts, thereby controlling the light-on state. The working principle of an optocoupler relay is similar to that of an optocoupler (in fact, it is the same when looking at the equivalent circuit diagram). First of all, we need to understand severalprofessional terms of relays: Form A=normally open contact Form B=Normally closed contact Form C=conversion contact Form E=bistable switch AT=Ampere Turns Parameter used to describe magnetic field sensitivity NC is a normally closed contactnormal close NO is a normally open contactnormal open After understanding the above professional terms, you can also understand the nouns on DataSheet. For example, Panasonic’s AQW610 is used on my C8051F board. On the DataSheet of AQW610, this relay is “Form A&B”, that is, it has both normally open contacts and long-closed contacts. You can take a look at the equivalent circuit diagram of AQW610: There is a normally open contact and a normally closed contact.
