339_AC OPTOCOUPLER (Simulide R2116 or higher.)
The idea is to control a lamp at 220 ACV using an OPTOCOUPLER so that both circuits are isolated (The lamp circuit and the circuit that sends the signal to the optocoupler).
SCHEME:
ON/OFF control of the lamp is obtained through a diode bridge whose POSITIVE and NEGATIVE outputs are short-circuited by the high voltage transistor 2SC3320. This transistor is controlled by the output of the optocoupler, whose voltage Vceo must be greater than 311V. A simple test signal has been applied to the input of the optocoupler, 5V to turn ON the lamp and 0V to turn it OFF.
SUBCIRCUITS:
This example integrates several subcircuits located in the "data" folder into the ZIP. This folder must always be next to the "sim1" scheme so that it can be executed. A subcircuit is a "custom" circuit that accumulates a set of Simulide base components (primitive function) to obtain a new or an adapted function. These subcircuits are treated by Simulide as another component of its own structure. User can create his own subcircuits or use the ones published here in your own designs once the procedure is known, explained in detail in the Simulide tutorials: https://simulide.com/p/subcircuits/
