The DI/OT System Board is one of the main components of the Distributed I/O Tier project ecosystem. It is mechanically and electrically compliant with the Compact PCI Serial standard (CPCI-S.0). As part of the integration with the Sinara ecosystem for quantum physics experiments, DI/OT System Board will have two executions to serve both CERN and Sinara requirements.

The DI/OT System Board controls the whole DI/OT crate, communicating with up to 8 Peripheral Boards and higher layers of the control system using White Rabbit, Gigabit Ethernet or any other industrial fieldbus.
