Yes, you are right. Buttons and led are considered passive components. You need to consider the lenght of cables to get their capacitance and inductance. ■
Intrinsic safety
I make an intrinsic safety circuit in my project. I have IS bariers, IS blue cable and IS instruments ( pressure transmitter, selonoid valve etc.) But I want to learn, buton and LED signal lamp boxes are must be Eex ia certificated products. Because I think this equipments are passive.
I want to help to me please......
Thanks ■
