Hello everyone,
I have a Wiser for KNX device that was damaged by a power surge. After running diagnostics, I found that the following circuits were affected: KNX NCN5121, 88RY SVUB, SI8421AB, and 263A.
After several days of research, I discovered that the first circuit (NCN5121) is a microcontroller.
I would like to know if it’s possible to find this component already programmed on the market.
