Product Overview
The ABB TB810 (3BSE008560R1) functions as the primary fiber optic interface for the S800 I/O system. This 100% brand new original unit enables the expansion of the Modulebus to remote I/O clusters, transcending the distance limitations of standard electrical cabling. By converting electrical bus signals into optical pulses, the TB810 facilitates high-speed, interference-free data exchange between the central controller and distributed I/O stations in complex industrial environments.

Engineering Advantages
The TB810 Optical Port solves critical signal integrity and architecture challenges in automated facilities:
-
Total Electromagnetic Immunity: Because it uses fiber optic transmission, the TB810 eliminates data corruption caused by high-voltage motors, frequency converters, or lightning strikes. This makes it indispensable for applications in power plants and heavy manufacturing zones.
-
Galvanic Isolation: The optical link provides a complete electrical break between I/O clusters. This prevents ground loops and ensures that a fault in one remote station does not propagate through the bus to the main processor.
-
Ultra-Compact Footprint: Measuring only 40mm x 40mm, the module installs directly into the I/O station without requiring additional DIN rail space or complex mounting hardware.
-
Distance Flexibility: Unlike copper Modulebus connections limited to a few meters, the TB810 allows engineers to position I/O clusters dozens of meters away from the controller, optimizing floor space and reducing local wiring costs.
FAQs
Is the TB810 compatible with both plastic and HCS fiber?
Yes. The TB810 supports standard plastic optical fiber (POF) for short distances and Hard Clad Silica (HCS) fiber for longer runs, providing flexibility based on your specific plant layout.
Does this module require a separate power supply?
No. The TB810 draws its necessary operating power directly from the Modulebus connection on the I/O station base, simplifying the power distribution scheme within your cabinet.
How do I verify the signal strength of the optical link?
The TB810 integrates with the standard ABB diagnostics suite. You can monitor the communication health and signal integrity via the Control Builder M software or the diagnostic LEDs located on the associated CI810/CI820 Fieldbus Communication Interface.
Can I hot-swap the TB810 during operation?
While the S800 system supports many hot-swappable components, removing the TB810 will break the Modulebus ring or link, causing all downstream I/O modules to lose communication. Always perform replacements during a scheduled maintenance window or ensure system redundancy is active.
