ABB S800 I/O ModuleBus Communication

The TB810 converts the ModuleBus communication path to an optical fiber interface. Therefore, the unit supports optical transmission between compatible ABB S800 I/O ModuleBus sections where electrical bus cabling is not suitable.

The specified communication rate is 10 Mbit/s. In addition, the supplied data specifies a maximum transmission distance of up to 2 km when using single-mode fiber.

Because the interface uses optical transmission, the fiber path should remain physically separated from electrical power wiring and high-noise conductors. Installers should also maintain the specified fiber bend radius and protect optical connectors from contamination during installation.

The 24 VDC operating supply must be connected with correct polarity and appropriate industrial wiring practices. The TB810 should be installed only with compatible ABB S800 I/O equipment and ModuleBus configurations.

Frequently Asked Questions

Q: What communication medium does the TB810 use?
A: The TB810 uses a fiber optic ModuleBus interface and the supplied specification identifies single-mode fiber as the supported fiber type.

Q: What is the specified communication speed?
A: The specified ModuleBus optical communication rate is 10 Mbit/s (10 Mbps).

Q: What is the specified maximum transmission distance?
A: The supplied specification states a transmission distance of up to 2 km (1.24 miles). Actual installation performance depends on the selected fiber and optical link conditions.

Field Installation Guidelines

1. Verify the TB810 model and 3BSE008560R1 spare number before installation.
2. Confirm that the available supply is 24 VDC and matches the system wiring requirements.
3. Install the unit within the compatible ABB S800 I/O ModuleBus architecture.
4. Route optical fiber separately from power and high-current conductors.
5. Keep fiber connectors clean and capped until connection.
6. Avoid excessive bending, pulling, or mechanical loading of the optical cable.
7. Check the fiber type before connection; the supplied specification identifies single-mode fiber.
8. Inspect the optical path and connectors if communication faults occur.
9. Confirm ModuleBus communication after installation before placing the associated I/O segment into service.
