Its advantage is completly isolated power - you don't have to connect grounds and so less noise will reach rest of your circuit. To convert it to the proper signal we use the optocoupler. 4. It will give the logical output by receiving the IR signal. The maximum operating temperature for optocoupler is -30 to 100 degrees. In electric circuits, we use mostly filters to remove noise. The IR circuit can be designed by hand but we have a fully predesigned and small size integrated circuit IC knows as PC817 Optocoupler. An optocoupler (or an optoelectronic coupler) is basically an interface between two circuits which operate at (usually) different voltage levels. During soldering, the temperature range for optocoupler is 260 degrees. 3. Can you suggest a transistor in place of bc547/bc557 to handle current up to 1.5amps,because I want to operate car relay which consumes current up to 1.5 amps. It is mandatory to procure user consent prior to running these cookies on your website. The optocoupler has many uses due to its small and compact size as a control operation. The maximum current ratio at the collector will be 50mA. Nowadays IC has the best uses in IoT devices for switching and zero cross. are we to input a dim value from the serial monitor? The Electrical signal transfers between an input and an output side optically without any physical connection between both sides.
