It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

Utilizing the photo-sensitive nature of silicon, VMI has created a line of hermetically sealed, high voltage optocouplers and opto-diodes in versions that can be assembled in series configuration for ...
