I am doing a project that are not triggered by Arduino but utilizing a relay with a signal from LED signal.
I managed to trigger the relay only with 1 single relay type. OPTO single. OPTO 8 channel will unable to be triggered. Tried SSR also relay unable to be triggered.
Upon further investigation. I have notice the below are the value of LED signal voltage.
LED OFF Voltage : -6V
LED ON Voltage : +1.6V to +2.5V
Differennt in voltage during triggering 2.6V - 3.1V
I do believe the problem lies at the -6V when the led in in OFF possition.
Basically… i wish to use the same input powering the small LED to a brighter and larger LED powered by 12VDC/24VDC/240AC.
