ABB S800 I/O Output Architecture

The DO818 3BSE069053R1 integrates into the ABB S800 I/O architecture through ModuleBus communication and provides high-density digital output control. Each output channel uses a high-side driver with short-circuit protection, over-temperature protection, EMC protection components, inductive load suppression, and optical isolation from the ModuleBus.

Furthermore, the module divides the 32 outputs into two individually isolated groups of 16 channels. Each group includes a process voltage supervision input to monitor external field supply conditions. The output drivers provide current limiting functions for connected DC loads and maintain controlled switching behavior during field operation.

The ABB S800 platform supports I/O density scaling through modular backplane communication. Therefore, the DO818 enables compact installation for distributed control configurations requiring multiple 24 VDC switching points.

Firmware and ModuleBus Compatibility

The DO818 uses ABB S800 I/O ModuleBus communication for data exchange with the controller system. The module transfers output status information and diagnostic signals through the ModuleBus interface.

In addition, the S800 I/O family provides firmware flash compatibility management through the engineering configuration environment. The DO818 configuration must match the installed controller and I/O system revision requirements.
