PRODUCTS / Photocoupler

A coupler is consisted of one couple of emission and receiving elements.  It makes use of light to transmit signals, and then makes electrical insulation between input and output.  According to the feature of coupler, it can be considered as a relay or a signal transformer to completely isolate electrical current between input and output systems.  Transmitting signals between two systems, Input and Output, are using light mode to achieve each other.  Hence, it is the most important thing that two systems can be individual in grounding besides using same voltage.
