Product Overview
The ABB TK811V050 is a 5-meter duplex Plastic Optical Fiber (POF) cable engineered for optical ModuleBus connections in industrial automation systems. As part of the ABB S800 I/O family, this cable ensures reliable, high-speed data transmission between modules, reducing the risk of electromagnetic interference common in copper-based links. With its latching duplex connector, the TK811V050 provides a secure, tool-free connection that stays locked even under vibration—critical for harsh factory environments.

Industry Applications
The ABB TK811V050 excels in applications where reliable, noise-immune communication is paramount. Typical use cases include:
-
Process Automation: In chemical or pharmaceutical plants, the TK811V050 connects remote I/O modules to controllers, maintaining signal integrity over distances up to 5 meters despite the presence of variable frequency drives and other EMI sources.
-
Material Handling: For conveyor systems in warehouses, the cable's latching connector withstands constant vibration, reducing downtime caused by loose connections.
-
Power Generation: In turbine control systems, the POF cable provides galvanic isolation, protecting sensitive electronics from ground loops—a critical factor in high-voltage environments.
Installation & Setup Guidance
Installing the TK811V050 is straightforward. First, verify that both the module and the receiving port are equipped with compatible duplex optical connectors. Align the connector keyway with the port, then push gently until the latch clicks into place. Avoid bending the cable beyond a 25 mm radius to prevent fiber damage. When routing, use existing cable ducts or tie wraps, but do not overtighten—the POF is flexible yet can be crushed under excessive pressure. For optimal performance, keep the cable away from sharp edges and high-temperature surfaces.
Maintenance & Reliability
The TK811V050 requires minimal maintenance due to its robust plastic fiber construction. However, periodic inspection is recommended every 6 to 12 months. Check the connector ends for dust or scratches; if dirty, clean them with a lint-free cloth and isopropyl alcohol. Ensure the latch mechanism still clicks firmly. Because POF is less susceptible to breakage than glass fiber, the risk of failure is low, but physical damage from accidental pulling or crushing remains possible. Regular checks of cable routing can prevent such issues, extending service life and reducing total cost of ownership.
Compatibility & Integration
The TK811V050 is specifically designed for the ABB S800 I/O system, which is widely used in ABB's 800xA and Symphony Plus distributed control systems (DCS). It serves as the optical ModuleBus link between I/O modules and the communication interface, enabling high-speed data exchange. The cable is compatible with all S800 modules that feature an optical ModuleBus port, including AI, AO, DI, DO, and mixed-signal modules. For retrofits or expansions, verify that the existing modules support POF connections; older copper-based ModuleBus systems may require an adapter or module replacement.
Selection Guide & Purchasing Advice
Before purchasing the ABB TK811V050, confirm that your system uses the S800 I/O family and that the ModuleBus ports are optical. Check the required cable length—this model is 5 meters, which suits most cabinet layouts; if you need a different length, consider other ABB POF cable options.
