2. Key Features

• High-Speed Real-Time Data Transmission: Supports 100Mbps full-duplex data rates with ≤1ms latency—ideal for time-sensitive ABB automation networks (e.g., 800xA DCS controlling refinery distillation columns), ensuring process variables (temperature, pressure) are transmitted without delay.
• Dual-Layer EMI/RFI Shielding: Aluminum foil + 95% coverage copper braid block electromagnetic interference from industrial equipment (e.g., motor drives, welders)—prevents signal corruption (e.g., false sensor readings) that could cause control errors or production stoppages.
• Twisted-Pair Conductor Design: Two twisted pairs with differential twist rates minimize crosstalk (≤-60dB at 100MHz)—enables installation in dense cable trays (with other power/control cables) without signal interference, simplifying cabinet wiring.
• Halogen-Free Flame Retardancy (HFFR): HFFR PVC sheath emits minimal smoke and toxic gas in fire—complies with safety standards for enclosed industrial spaces (e.g., power plant control rooms) and public infrastructure, reducing health risks during emergencies.
• Wide Temperature & Environmental Adaptability: -40℃~+80℃ operating range, 2g vibration resistance, and 95% humidity tolerance—operates reliably in extreme environments (e.g., arctic oil rigs, desert solar plants, coastal refineries) without performance degradation.
• ABB Automation Ecosystem Compatibility: Optimized for ABB AC800M PLCs, 800xA DCS, and remote I/O units—works seamlessly with ABB’s communication protocols (AC 800M backplane bus) and connectors (M12 D-coded), eliminating compatibility issues and reducing commissioning time.
• Long-Distance Signal Integrity: Low attenuation (≤0.5dB/m at 100MHz) and high SNR (≥30dB) ensure data integrity over 100m+ distances—enables decentralized control (e.g., remote I/O in mining tunnels) without signal repeaters, lowering system costs.

3. Application Fields

• ABB AC800M/800xA Automation Networks: Primary application—data transmission in ABB control systems:
  • Refinery DCS Systems: Connects 800xA DCS modules (e.g., AI830 analog input) to AC800M PLCs in refinery distillation units; dual shielding resists EMI from high-voltage process cables, ensuring accurate transmission of temperature/pressure data (critical for hydrocarbon separation).
  • Power Plant Control Loops: Transmits real-time data between AC800M PLCs and remote I/O units (e.g., DI830 digital input) in coal-fired power plants; 100Mbps data rate enables ≤1ms latency for boiler feedwater control, preventing overpressure incidents.
• Industrial Manufacturing Automation: Data backbone for production lines:
  • Automotive Assembly Lines: Links ABB robotic control units to 800xA DCS via PROFINET RT; twisted pairs minimize crosstalk from nearby welding equipment, ensuring precise robot movement (±0.1mm accuracy) for vehicle body assembly.
  • Electronics Production Cleanrooms: Connects AC800M PLCs to compact 800xA I/O modules for semiconductor manufacturing; HFFR sheath meets cleanroom standards (low particle emission), while low attenuation enables data transmission over 50m+ cleanroom aisles.
• Mining & Minerals Decentralized Control: Data transmission in remote mining environments:
  • Underground Mining Control Systems: Connects surface AC800M PLCs to underground remote I/O units (e.g., for conveyor speed monitoring); -40℃ low-temperature rating withstands cold mine shafts, and dual shielding resists EMI from mining machinery (crushers, hoists).
  • Open-Pit Mine Material Handling: Transmits data between 800xA DCS and mobile I/O units on conveyor belts; 2g vibration resistance handles conveyor motion, while IP67 M12 connectors (when used with the cable) protect against dust and water spray.
• Energy & Utility Infrastructure: Data transmission in energy systems:
  • Wind Turbine Control Networks: Connects on-turbine AC800M PLCs to offshore 800xA DCS; HFFR sheath resists saltwater corrosion, and wide temperature range (-40℃~+80℃) handles offshore weather extremes (high winds, temperature swings).
  • Solar Plant Inverter Control: Links solar inverter I/O units to 800xA DCS via Modbus TCP; low attenuation enables 100m+ transmission between inverter arrays and the central control room, ensuring real-time power output monitoring.
• Water & Wastewater Treatment: Data transmission for process control:
  • Wastewater Treatment Plants: Connects 800xA DCS modules to remote I/O units (e.g., AO830 analog output) for chemical dosing control; 95% humidity tolerance withstands damp treatment facility environments, while dual shielding resists EMI from pump motors.
