The ABB TK812V050 is a specialized industrial-grade simplex plastic optical fiber (POF) designed for cost-effective, unidirectional medium-range communication in ABB automation systems—specifically optimized for ABB S800 I/O architectures, 800xA DCS, and AC800M PLCs where one-way data transmission (e.g., sensor-to-controller signals) over moderate distances is required. It functions as a "unidirectional optical link," utilizing a single PMMA (polymethyl methacrylate) fiber core to transmit optical signals between industrial components, offering inherent EMI immunity, flexibility, and durability for indoor industrial environments. As an extended-length variant of the TK812 series, it balances performance and cost for applications requiring longer unidirectional communication paths (up to 50m at 100Mbps) without the complexity of glass fiber. Below is its detailed specification:
- Product Model: TK812V050
- Product Series: ABB TK Series Simplex Plastic Optical Fibers (Extended-Range Unidirectional Communication)
- Core Function: Enables unidirectional optical data transmission over medium distances between ABB automation components; provides EMI-immune communication for sensor/actuator signals; simplifies wiring with a single-fiber design; ensures compatibility with ABB optical interfaces (e.g., TB811, TU849)
- Optical & Transmission Specifications:
- Environmental Ratings:
- Operating Temperature Range: -20℃~+75℃ (-4℉~167℉)
- Storage Temperature Range: -40℃~+85℃ (-40℉~185℉)
- Humidity Tolerance: 5%~95% RH (non-condensing, 40℃)
- Chemical Resistance: Resistant to mineral oils, mild acids, alkalis, and industrial detergents (IEC 60068-2-54)
- Vibration Resistance: 10~500Hz, 1.2g acceleration (no fiber breakage or signal degradation)
- Compliance Standards: CE, RoHS, ABB Optical Communication Standard V2.1, UL 94 V0 (flame retardancy), IEC 61032 (electrical equipment safety)
- Extended-Range Unidirectional Transmission: Supports 50m at 100Mbps and 150m at 10Mbps—ideal for medium-distance one-way communication (e.g., sensor arrays in large warehouses to central PLCs), eliminating the need for expensive glass fiber in non-bidirectional applications.
- EMI/RFI Immunity: Plastic optical fiber inherently rejects electromagnetic and radio frequency interference—critical for installation near high-noise equipment (e.g., motor drives, welders) in automotive plants or steel mills, where copper cables suffer signal corruption.
- High-Purity PMMA Core: Low attenuation (≤10dB/km) enables longer distances than standard POF—maintains signal integrity over 50m links (e.g., between distant process skids and main control cabinets in chemical plants).
- Tool-Free Installation: Large 1mm core and push-pull connectors simplify termination—field technicians can achieve reliable connections without polishing or alignment tools, reducing installation time by 40% vs. glass fiber.
- Robust 3.5mm Jacket: Flame-retardant (UL 94 V0) and chemical-resistant PVC jacket—withstands industrial hazards (oil exposure, mechanical stress) in refineries, food processing plants, and manufacturing facilities.
- Space-Efficient Design: Slim profile (3.5mm) reduces wiring clutter in control cabinets—enables dense routing alongside power cables and copper communication lines without signal interference (thanks to EMI immunity).
- Seamless ABB Compatibility: Integrates with ABB optical components (TB811, S800 optical modules)—ensures system-wide reliability and eliminates the need for adapters or protocol converters.
- ABB Automation System Medium-Range Links: Primary use in extended unidirectional paths:
- 800xA DCS Remote Sensor Networks: Transmits 4~20mA flow/pressure data from remote process skids (50m from main cabinet) to S800 AI modules—low attenuation ensures accurate measurements for process control in refineries.
- AC800M PLC Factory Floor Monitoring: Connects 150m-long links from conveyor belt sensors (DI) to AC800M PLCs in large automotive plants—eliminates EMI from robotic welders that corrupt copper-based DI signals.
- High-Noise Industrial Zones: EMI-immune communication near heavy machinery:
- Steel Mill Continuous Casting Lines: Sends temperature data (thermocouple signals) 40m from casting molds to 800xA DCS—POF’s noise immunity avoids false high-temperature alarms from nearby induction heaters.
- Mining Processing Plants: Transmits ore crusher status signals (DI) 30m to control cabinets—resists RFI from high-voltage motors, ensuring reliable equipment monitoring in dusty environments.
- Medium-Distance Process Monitoring: Connecting distributed sensors:
- Water Treatment Plant Pipeline Sensors: Links pH and turbidity sensors (50m from SCADA cabinet) to S800 I/O modules—unidirectional design reduces costs vs. duplex fibers, while EMI immunity avoids ground loops from pump systems.
- Food Processing Plant Oven Monitoring: Transmits temperature data (40m) from industrial ovens to 800xA DCS—oil-resistant jacket withstands occasional grease exposure, unlike copper cables which corrode.
- Cost-Effective Retrofit Projects: Upgrading legacy systems with longer links:
- Chemical Plant Legacy DCS Upgrades: Replaces 50m copper cables with POF for sensor-to-controller links—eliminates ground loops that caused measurement drift in the old system, reducing process variability by 20%.
- Warehouse Automation Systems: Connects barcode scanners (50m from PLC) to S800 DI modules—simplex design reduces wiring costs, while flexibility simplifies routing around racking and equipment.
