What Is the Honeywell 8939-HN?

The Honeywell 8939-HN is a Multi-Mode Fiber Optic Extender IOTA used as part of the Honeywell Series 8 I/O extension solution.

In the Series 8 architecture, Series 8 I/O modules communicate with the S8 C300 through I/O Link connections. Honeywell’s Fiber Option Extender solution enables the I/O Link to extend beyond the Series 8 cabinet, making remote Series 8 I/O installations possible.

The 8939-HN is the Multi-Mode Fiber Optic Extender IOTA within this architecture.

It may be required for Honeywell DCS maintenance, replacement of existing hardware, control system expansion, remote I/O projects, and industrial spare-parts requirements.

Key Features of Honeywell 8939-HN

• Honeywell part number: 8939-HN
• Multi-Mode Fiber Optic Extender IOTA
• Designed for Honeywell Series 8 I/O extension applications
• Used with the S8 C300 architecture
• Supports extension of the I/O Link beyond the Series 8 cabinet
• Suitable for remote Series 8 I/O applications
• Part of Honeywell’s Series 8 I/O Extension Solution
• Suitable for maintenance, replacement, and system expansion projects

What Does the 8939-HN Do?

The primary purpose of the 8939-HN Fiber Optic Extender IOTA is to support remote Series 8 I/O installations.

In a standard Series 8 configuration, the S8 C300 and associated Series 8 I/O communicate through I/O Link connections. When an application requires I/O to be installed outside the local Series 8 cabinet, the fiber optic extension solution allows the I/O Link to be extended to the remote location.

This architecture can be useful in large industrial facilities where controllers and field I/O equipment cannot always be installed within the same cabinet or immediate area.

Typical Applications

The Honeywell 8939-HN may be required for:

• Honeywell Series 8 DCS maintenance
• Remote Series 8 I/O installations
• Existing 8939-HN replacement
• DCS modernization and expansion projects
• Plant maintenance and shutdown projects
• MRO spare-parts procurement
• Replacement of damaged or aging automation hardware
• Industrial process control applications
• Honeywell C300 / Series 8 spare-parts requirements

Before purchasing replacement hardware, customers should verify the complete part number and existing system configuration.

If you are unsure whether 8939-HN is the correct part for your application, send HKXYTECH a photo of the existing unit or nameplate together with your required quantity.
