The Foxboro P0922QS Foundation Fieldbus Communications Module is a channel-isolated H1 Foundation Fieldbus interface (FBM228) designed for Foxboro control systems. It supports four communications channels, providing independent Foundation Fieldbus signal paths within a single module. This P0922QS unit interfaces Foxboro controllers with Foundation Fieldbus H1 instruments via the FBM228 platform, preserving channel isolation in Fieldbus communications.
