With high anti‑interference and high transmission stability, it effectively solves problems such as electromagnetic interference and signal attenuation on site, making it a key communication component ensuring accurate and stable signal transmission in industrial automation systems for power, chemical, oil and gas, metallurgy, and other industries.
1 Technical Data
1.1 Electrical and Communication Parameters
Type: Industrial‑grade optical fiber interface module. Core functions: bidirectional conversion between electrical and optical signals, high‑speed data transmission, communication link status monitoring, supporting optical fiber communication in industrial automation systems.
Power supply: 24 VDC ±10%, suitable for industrial standard DC power systems, with wide voltage tolerance to ensure stable signal transmission and reliable communication links even under unstable on‑site voltage.
Power consumption: ≤ 5 W. Low‑power design reduces overall energy consumption of the automation system, lowers self‑heating, improves operational stability, and requires no additional cooling.
Transmission rate: Supports high‑speed data transmission up to 100 Mbps, meeting the demand for fast transfer of large volumes of real‑time data (e.g., equipment operating parameters, control commands) in industrial automation systems with negligible latency.
Optical interface: Equipped with standard SC/ST optical fiber interfaces (subject to factory configuration). Supports single‑mode and multi‑mode fiber (selectable based to on‑site transmission distance), compatible with commonly used industrial fiber types for convenient field wiring and connection.
Transmission distance: Up to 10–20 km for single‑mode fiber and 500 m–1 km for multi‑mode fiber. Flexible selection according to on‑site equipment layout to satisfy long‑distance communication needs.
Communication protocols: Supports ABB proprietary protocols and common industrial communication protocols, enabling seamless compatibility with AC 800M, Advant OCS, and other control systems for bidirectional data exchange with other modules and field devices.
Signal conversion: Provides bidirectional conversion between RS‑485/Ethernet electrical signals and optical signals, adapting to different field equipment interfaces and flexibly connecting various industrial sensors, actuators, and controllers.
1.2 Mechanical and Installation Parameters
Structure: Standardized modular package, dimensions approx. 120 mm × 80 mm × 40 mm (W × H × D). Compact design suitable for standard layouts in industrial control cabinets, facilitating system integration and space planning, and allowing co‑installation with other control and communication modules.
Weight: Approx. 0.5 kg. Lightweight for easy on‑site installation, removal, and maintenance, reducing labor costs while meeting cabinet load requirements.
Mounting: Standard DIN‑rail mounting, compatible with common industrial cabinet setups. Easy and secure installation, resistant to on‑site vibration, ensuring reliable connections to fiber and cables and preventing communication interruptions.
Interface layout: Clear layout with separated optical and electrical interfaces for easy wiring and troubleshooting. Anti‑mismatch design prevents damage or communication faults caused by incorrect connections.
1.3 Environmental and Reliability Parameters
Operating temperature: -25 °C to +60 °C. Wide temperature range adapts to fluctuations in power, chemical, oil and gas, and other industrial sites, enabling stable long‑term operation in extreme cold and heat without extra temperature control.
Storage temperature: -40 °C to +85 °C. Excellent storage adaptability for long‑term spare part storage without special conditions, reducing inventory management costs.
Immunity: Industrial‑grade EMC design with superior resistance to electromagnetic interference, vibration, and dust. Complies with IEC 61000 standards, effectively suppressing strong interference from high‑voltage equipment and inverters to avoid signal distortion or communication outages.
Reliability: 12‑month warranty. Uses high‑quality industrial components and hermetic packaging with excellent water and dust protection. Low long‑term failure rate; mean time between failures (MTBF) ≥ 50,000 hours, ensuring continuous stable communication links.
Protection degree: IP20, suitable for indoor industrial control cabinets, providing protection against dust and light splashing to prevent short circuits and internal faults for stable long‑term operation.
2 Key Features
2.1 High‑Speed Optical Transmission for Real‑Time Data
Supports 100 Mbps high‑speed data transmission and fast bidirectional electrical‑optical conversion, ensuring rapid transfer of real‑time data such as equipment parameters and control commands with minimal delay. Satisfies real‑time control requirements in industrial automation systems, improving control accuracy and response speed.
2.2 High Immunity for Harsh Industrial Environments
Industrial‑grade EMC design and hermetic packaging deliver exceptional electromagnetic interference resistance, effectively suppressing interference from high‑voltage equipment and inverters. Excellent vibration and dust resistance resolve issues of interference and signal distortion in traditional cable communication, guaranteeing stable links for power, chemical, metallurgy, and other demanding industries.
2.3 Long‑Distance Transmission for Flexible On‑Site Layout
Supports both single‑mode and multi‑mode fiber with ranges up to 10–20 km and 500 m–1 km respectively. Flexible selection based on site layout eliminates the need for signal amplifiers, lowering integration costs while mitigating long‑distance signal attenuation for stable data transfer.
2.4 High Compatibility for Multi‑System Integration
Fully compatible with ABB AC 800M, Advant OCS, and other control systems, supporting ABB proprietary and common industrial protocols for seamless connection to internal modules, I/O units, and field devices. Also serves as a communication upgrade spare for legacy systems, enabling link improvement without major reconstruction and enhancing reliability.
