Good morning, I use a K8055N card to control a bi-fuel boiler.
I connected to the digital outputs 5 relays. Sometimes it can happen that when one or more relays are activated, the 8055n board crashes and executes the microprocessor restarts, in fact the led number 8 flashes, and soon after the board reconnects.
What this reboot can be due to? May be a peak of tension introduced in the circuits by the relays? or another reason?
how can i avoid such reboot? additional filter condensers on the pic? or diodes feeding of the realys?
