HONEYWELL 8939-HN Fiber Optic Extender Module

Product Description:

The Honeywell 8939-HN is a Fiber Optic Extender Module for the Experion® PKS C300 controller and Series C I/O architecture. This module serves as a critical communication bridge, allowing for the long-distance extension of the I/O link between the C300 controller and remote Series C I/O racks.By converting electrical signals into optical signals, the 8939-HN enables seamless data transmission over several kilometers, overcoming the distance limitations of standard copper cabling while providing superior immunity to electromagnetic interference (EMI).

Frequently Asked Questions (FAQ):
1.Does the 8939-HN support redundant I/O Link configurations?

Yes. The 8939-HN is designed for mission-critical industrial applications and fully supports redundant I/O Link architectures. In a standard setup, two modules are used (Link A and Link B) to ensure that if one fiber path fails, the C300 controller maintains uninterrupted communication with the remote I/O modules.

2.What is the primary function of the Honeywell 8939-HN module?
The 8939-HN is a high-speed Fiber Optic Extender Module for Honeywell’s Experion PKS (Process Knowledge System). It is specifically used to extend the I/O Link between a C300 Controller and remote Series C I/O racks. By converting electrical signals to optical signals, it allows for long-distance communication (up to several kilometers) without electromagnetic interference.

3.Is the 8939-HN module hot-swappable?
Yes, in a redundant configuration, the 8939-HN is hot-swappable. You can replace a faulty module while the system is powered and the other redundant link is active, significantly reducing MTTR (Mean Time To Repair) and avoiding plant downtime.

4.How do I get the price of 8939-HN?

5.How are the 8939-HN packaged?
8939-HN packaging generally involves multiple layers of protection to ensure safe transit.

Application:
Oil and Gas (Midstream and Downstream): Large-scale petrochemical integrated production facilities, refineries, and liquefied natural gas (LNG) receiving stations.
Chemical and Pharmaceutical: Fine chemical and biopharmaceutical production lines, monitoring of reaction vessels, pressure vessels, and batching systems.
Electricity and Utilities: Distributed control systems (DCS) of power plants, boiler rooms, turbine rooms, and switch stations.
Water Treatment and Environmental Protection: Sewage treatment plants or remote water supply pumping stations.

Core Function:
I/O Link Expansion: This module is used to extend the I/O links from the Series 8 cabinet to remote locations, supporting communication between the S8 C300 controller and the remote I/O module.
Remote Application: Enables the Series 8 I/O to be deployed in locations far from the main control cabinet, enhancing the flexibility of distributed control.
Redundancy Support: Comes with a pair of redundant Combo cable interfaces to ensure the high availability of the connection between the controller and the I/O module.
