The ABB SDCS-COM-81 DDCS communication board, order code 3ADT220134R0001, provides a 10 Mbaud channel zero interface for ABB drive systems. It is the dedicated communications link between an ABB drive controller and the power stage or between drives in a multi-drive configuration. The 10 Mbaud rate supports high-speed data exchange for real-time control and diagnostics over the DDCS fiber-optic ring.
Integration note
The board is card-format at 22.5 cm x 15 cm x 5 cm and mounts inside an ABB drive cabinet on the designated slot for the DDCS interface. The single CH0 port connects via a fiber-optic cable; polarity and routing follow the drive's communication manual. No field-configurable addressing exists — the channel is fixed. Verify the drive firmware revision supports the 10 Mbaud rate before commissioning.
