Hi guys, need little help if possible.
I will post a pcb with some weird markings on optocouplers/photocouplers not possible to find. I guess some weird protection design.
PCB itself powers from 2cpr Battery rated 6V, 1.4A.
It has a 2/2-way solenoid cartridge servo controlled valve to be run as soon as infra and photo led catches something and send the current to servo..
Since I have 3 identical taps, 2 are with same burnings/should I say optocoupler.
If you can help me determining which optocoupler should I replace it with would me a great thing for me......
Thanks !
P.S Second picture is a picture of still working pcb, and you can see that markings on optocoupler differs from the previous pcb. Second picture is a full pcb layout!
