ESP32 input problem from contacts of Thermal-magnetic circuit breaker - gokhan - 12-30-2021
Hi
I am designing a pressure controlled vacuum tank.
Software of ESP32 and
Nextion screen is OK
But I have problem when
I get digital input from (TMCB)
thermal magnetic circuit protector( schneider gv2me14)
When red fault contacts close I want to get information of fault of motor. But esp32 reset itself .

do you have connect the detect signal port to ESP32's GPIO directly? Is there an optocoupler isolation circuit?

No I don't use optocoupler
Would you advise optocoupler module or any other product ?

maybe your contactor have interference signal.
