Product Description
The ABB DO820, also identified by the base model DO820, is a digital output module for the ABB S800 I/O system. It controls discrete field devices by switching electrical output signals through the module's output channels. The module interfaces with the control system through the S800 I/O architecture.

S800 I/O Output Signal Characteristics
The DO820 belongs to the ABB S800 I/O product family. Its digital output channels provide discrete electrical control signals to connected field devices.
During installation, verify the output voltage, channel current rating, load type, and common-terminal arrangement against the module's official hardware documentation. Additionally, confirm the compatible Module Termination Unit (MTU) before connecting field wiring.
The supplied information does not establish the module's exact isolation boundaries, diagnostic coverage, or redundant operating modes. Therefore, these characteristics require confirmation from the applicable ABB technical manual.
Frequently Asked Questions (FAQ)
Q: How many output channels does the ABB DO820 provide?
A: The supplied product information identifies 8 digital output channels. Confirm the channel configuration against the official ABB documentation before commissioning.
Q: Can the DO820 operate with a redundant MTU configuration?
A: The supplied information does not confirm a specific redundant MTU arrangement. Check the ABB S800 I/O hardware compatibility documentation for the required termination unit and system configuration.
Q: What electrical parameters should be checked before connecting field loads?
A: Verify the rated output voltage, maximum channel current, load characteristics, terminal assignments, and applicable protection requirements before energizing the module.
Field Installation Guidelines
- Confirm the complete module designation and compatibility with the installed S800 I/O system.
- Select the correct MTU according to ABB hardware documentation.
- Isolate the relevant power sources before installing or removing the module.
- Verify terminal assignments and field-device polarity before connecting conductors.
- Route output wiring separately from sensitive analog signal cables where practical.
- Apply the cabinet grounding and shield termination practices specified by the system design.
- Check field-load current against the documented channel rating.
- Inspect module seating, terminal connections, and front-panel indicators during commissioning.
- Confirm output operation through controlled functional testing before placing the equipment into service.
