ABB S800 I/O High Side Driver and Protection Characteristics

The DO815 uses eight individually controlled high side output drivers for 24 VDC field devices. Each channel integrates optical isolation, output status indication, EMC protection, and inductive load suppression components.

Furthermore, the module divides the outputs into two isolated groups with four channels per group. The integrated protection circuits detect short circuits, overload conditions, undervoltage states, and active signal open load conditions.

The DO815 follows ABB S800 I/O backplane communication architecture and supports I/O density scaling through ModuleBus connectivity. The module provides direct digital signal execution between the control system and connected field actuators.

Frequently Asked Questions

Q: What type of output driver does the ABB DO815 use?
A: The DO815 uses a high side driver with current limiting. Each output channel includes short circuit and overload protection.

Q: Does the DO815 support redundant operation or safety integrity functions?
A: No. The DO815 does not provide redundancy or high integrity functions. It operates as a standard digital output module within the S800 I/O platform.

Q: How are output channels electrically isolated?
A: The eight outputs are arranged into two isolated groups. Each group contains four output channels and is isolated from ground.

Field Installation Guidelines

Install the DO815 module in an ABB S800 I/O configuration using compatible Module Termination Units such as TU810, TU812, TU814, or TU830.

Connect field wiring according to the approved ABB installation documentation. Keep output signal wiring separated from high voltage power conductors to reduce electromagnetic interference.

Verify the ModuleBus connection before system commissioning. Confirm that field devices match the 24 VDC output range and maximum current specification.

Ensure protective grounding, enclosure requirements, and environmental conditions comply with the applicable IEC and installation standards.
