Product Introduction
When optical isolation and high-speed data integrity are critical in your automation network, the ABB TK811V050 POF Cable delivers a robust solution. This 5-meter long, duplex Plastic Optical Fiber (POF) cable is specifically designed for optical ModuleBus connections within ABB's S800 I/O system. Its latching duplex connectors provide a secure, vibration-resistant link, ensuring consistent performance in demanding industrial environments. As part of the trusted ABB portfolio, the TK811V050 simplifies network architecture while maintaining signal purity over short distances.
Technical Specifications Breakdown
The TK811V050 POF Cable is defined by a few key parameters that directly impact its application. The cable length is exactly 5 meters, which is ideal for connecting modules within a cabinet or between nearby cabinets. It uses duplex plastic fibre, meaning two optical fibers are bundled together for simultaneous bidirectional communication. The latching duplex connector type ensures a positive mechanical lock, preventing accidental disconnection. With a weight of only 0.02 kg (and 0.045 kg according to general info), this cable is extremely lightweight, reducing strain on ports and simplifying routing. The article number 3BSC950107R2 identifies this specific variant for ordering and traceability.
Industry Applications
In process control and manufacturing automation, the TK811V050 POF Cable is commonly used to link S800 I/O modules to their bus couplers or controllers. For example, in a chemical plant where electromagnetic interference (EMI) can corrupt copper-based signals, this optical cable provides galvanic isolation and noise immunity. Another typical scenario is in high-voltage switchgear monitoring, where the plastic optical fiber's non-conductive nature adds a layer of safety. The 5-meter length is sufficient for most cabinet-to-cabinet connections without excess slack.
Installation & Setup Guidance
Installing the TK811V050 is straightforward. First, ensure the latching connectors are oriented correctly before insertion into the corresponding ModuleBus ports on the S800 modules. Push firmly until you hear a click, indicating the latch has engaged. Avoid sharp bends in the cable; the minimum bend radius for plastic optical fiber should be respected to prevent signal loss. Route the cable away from high-voltage power cables to maintain signal integrity. No special tools are required for installation.
Maintenance & Reliability
The TK811V050 POF Cable requires minimal maintenance due to its solid-state optical construction. Periodically inspect the connectors for dust or debris and clean them with a lint-free cloth if necessary. Verify that the latching mechanism is not damaged, as a loose connection can cause intermittent communication faults. The cable's plastic jacket resists many industrial oils and chemicals, but avoid prolonged exposure to solvents. Given its lightweight design and robust connectors, the TK811V050 offers long service life in fixed installations.
Compatibility & Integration
This cable is designed specifically for ABB's S800 I/O system, which includes a wide range of analog and digital modules. It connects the I/O modules to the ModuleBus interface, enabling communication with ABB AC 800M controllers or other compatible systems. The duplex optical fiber supports the ModuleBus protocol, ensuring deterministic data exchange. Always verify that your S800 baseplate or coupler has the correct optical port before ordering.
Selection Guide & Purchasing Advice
Before purchasing the TK811V050, confirm your required cable length. This model is fixed at 5 meters; if you need a different length, consult the ABB S800 catalog for alternatives. Ensure your system uses the duplex POF ModuleBus standard, not single-fiber or glass optical variants. SpareTechPLC stocks this exact ABB 3BSC950107R2 cable, ensuring genuine parts for your critical automation network. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Frequently Asked Questions
Q1: Can the TK811V050 be used with non-ABB equipment?
A1: The TK811V050 is designed for ABB S800 ModuleBus optical connections. It may work with other systems using the same duplex plastic optical fiber standard and latching connectors, but compatibility is not guaranteed.
Q2: What is the maximum distance supported by this cable?
A2: The TK811V050 is a fixed 5-meter cable. For longer distances, you would need a different POF cable or a fiber optic converter.
Q3: Is the TK811V050 immune to electrical noise?
A3: Yes, as a plastic optical fiber cable, it provides galvanic isolation and is inherently immune to electromagnetic interference (EMI), making it ideal for noisy industrial environments.
Q4: How do I clean the connectors on the TK811V050?
A4: Use a lint-free cloth or optical cleaning swab with isopropyl alcohol if needed. Gently wipe the ferrule end-face. Avoid touching the polished surface.
Q5: Does the TK811V050 come with a warranty?
A5: Warranty terms depend on the supplier. Contact SpareTechPLC for specific warranty information on this ABB cable.
