OPTOCUPLOR – CONTROL CIRCUITS WITH PHOTOTRANSION SCHEMATIC CIRCUIT DIAGRAM

Optocouplers are led – photodiode, led – phototransistor, led – photo thyristor or led – photo triac.

OPTOCUPLOR - CONTROL CIRCUITS WITH PHOTOTRANSION SCHEMATIC CIRCUIT DIAGRAM

The optocoupler outputs when A1 and A2 switch is closed. (T1) The negative signal comes to the base of the transistor (-). (T1) transistor is switched on. (T2), the (T2) transistor is switched on and the relay operates. The motor, which is connected to the normally open ends of the relay, operates as a result of energized state change.

If values ​​that can increase the output of the resistance values ​​(T2) transistors used in this circuit can be increased to very large values, the motor can be energized and operated directly on the transistor as shown in Figure  (Steel). it will have sensitive results.
