Key System Functions

Processor & Fieldbus Interconnect: Acts as the physical base connector board allowing the CPU board to communicate with local I/O sub-assemblies and Advant Fieldbus 100 (AF100) networks.

Integrated Field Wiring Termination: Interfaces plant control signals and supply power directly to the AC 80 core chassis without external intermediary racks.

Compact Footprint: Engineered specifically for the compact AC 80 architecture, housing control, power, and communications in a unified footprint.
