Features:
- Provides Reliable Extension Of Series 8 I/O Links Over Fiber
- Ensures High-Speed Communication With Redundant IO Connectivity
- Delivers Robust Operation Under Harsh Industrial Conditions
The Honeywell 8939-HN is a multimode fiber optic extender IOTA designed for Experion® PKS Series 8 systems. It enables remote deployment of Series 8 I/O modules by extending the connection from the S8 C300 controller, allowing users to configure distributed control networks efficiently. Compared to earlier extender models, it provides faster data transmission and enhanced link reliability.
This module supports redundant Combo cable interfaces for secure IO Link connections, ensuring continuous communication between the controller and connected I/O modules. Its multi-mode fiber interface simplifies integration, while LC/LC connectors standardize connectivity across the Series 8 system.
The Honeywell 8939-HN operates reliably across a wide range of environmental and mechanical conditions. It withstands variable temperatures, relative humidity, and mechanical shocks, offering a dependable solution for industrial sites. Its robust design makes it an ideal choice for extending Series 8 I/O links in demanding applications.
The 8939-HN Honeywell Multi-Mode Fiber Optic Extender IOTA may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Electrical Isolation: Utilizing optical fiber as the transmission medium provides inherent electrical insulation. This completely eliminates loop currents caused by ground potential differences and protects the controller from field-side lightning strikes or high-voltage surges.
- Corrosion Protection: Standard G3 conformal coating, compliant with ANSI/ISA-S71.04 standards, withstands corrosive gases such as hydrogen sulfide and chlorine commonly found in chemical plants or refineries.
- Hazardous Area Certification: Compliant with international certifications such as Class I, Division 2, and ATEX/IECEx, allowing installation in industrial Zone 2 environments with explosive gas risks.
- Intrinsically Safe Integration: Although the optical fiber itself is not electrically charged, as part of the Series 8 link, it supports use with intrinsically safe I/O, ensuring the overall system's process safety.
- Remote Distributed I/O Deployment: When field devices are far from the C300 control cabinet (e.g., more than 100 meters but less than 2 kilometers), a fiber optic connection can be used to connect the remote I/O cabinet, eliminating the need for bulky copper multi-core cables.
- Cross-Building/Area Connections: Suitable for signal connections between tank farms, loading/unloading stations, or different production workshops, solving electromagnetic interference problems in cross-regional communication.
- Strong Electromagnetic Interference Environments: In areas with dense large motor control centers (MCCs) or frequency converters (VFDs), fiber optic extenders can ensure signal integrity of the control link.
- System Redundancy Expansion: In applications requiring extremely high availability, its dual redundant interfaces can be used to build highly reliable remote links.
- Long-Distance High-Speed Transmission: Supports deterministic communication at 10 Mbps, enabling lossless signal transmission over several kilometers on multimode fiber with extremely low latency, meeting real-time control requirements. Reduced cabling costs: Replacing a large number of copper signal cables with fiber optic cables not only reduces material costs and construction complexity but also lightens the load on cable trays.
- Simplified system maintenance: Supports hot-swapping, allowing expansion modules to be replaced without affecting system operation. Simultaneously, diagnostic information for the fiber optic link can be monitored in real time through the Experion system software.
- Wide temperature adaptability: Its operating temperature range is -40°C to +85°C, meaning it can be directly installed in outdoor cabinets without air conditioning systems, improving system deployment flexibility.
