Redundant universal IO modules with integrated galvanically isolated (GI) and intrinsically safe (IS) barriers

A system includes a back plane having at least one primary module and at least one secondary module that is redundant to the at least one primary module. The back plane is configured to limit energy from the at least one primary module and the at least one secondary module to a field device. The at...

Beschreibung
Zusammenfassung:	A system includes a back plane having at least one primary module and at least one secondary module that is redundant to the at least one primary module. The back plane is configured to limit energy from the at least one primary module and the at least one secondary module to a field device. The at least one primary module includes a first plurality of channels and is configured to provide channel to channel isolation among the first plurality of channels. The at least one secondary module includes a second plurality of channels and is configured to provide channel to channel isolation among the second plurality of channels.
