ABB S800 I/O Backplane and I/O Density Characteristics

The DO814 operates as an ABB S800 I/O digital output device with 16 current sinking channels. The module receives control commands through the ModuleBus interface and transfers discrete output signals to connected field devices.

Additionally, the S800 I/O architecture supports I/O density scaling through modular channel allocation. The DO814 provides compact digital output expansion for systems requiring multiple 24 VDC discrete actuators, solenoids, and control circuits.

The module uses current limiting output technology to control load current and protect output channels against abnormal electrical conditions. Therefore, field wiring design must consider load characteristics and cable routing requirements.
