It is a general semiconductor element has only one ground terminal , but the photocoupler has one each on the input and output side, both of which are electrically insulated inside. To insulate, an electrical signal is once converted into an optical signal inside and made into the electrical one again. In order to do this, a light emmiting diodeL and a light receiving element are internally combined to transfer or transmit the signal by means of light.

problem sa psu ang unit mo, regulator ic may tama.. and check other componests dyn,ecap maliit palitan mo narin... photo coupler cirquit ang nagdedetect ng b+ kung tumataas o bumababa ang B+ ng unit isend nya sa regulator cirquit para maregulte ang tamang B+ mo,para sakto ang B+... |

I think it SHOULD be called OPTO coupler and not PHOTO coupler.
OPTO means light.
PHOTO generally means picture.
To test your opto coupler please get the part number and data sheet first so alam natin ang pinouts. Then we can show you how to test.
