IIM board (Input Interface Module)
IIM board (Input Interface Module)
(OP)
When wiring input sensors as inputs to digital controllers, I sometimes see that a "IIM board" being used. My understanding is that they are used for electrical isolation between field devices and the controller.
My question is , when is it a must, and when is it an option? Or is it an extra protection (i.e you don't necessarly have to have it)?
Thanks
