Honeywell 8937-HN2 Fiber Optic Extender Module

Description

The Honeywell 8937-HN2 is a dedicated fiber optic extender module engineered for industrial automation and control system networks. Designed to operate as part of Honeywell control infrastructure, this module facilitates robust, high-speed data transmission between remote system nodes, controllers, and input/output architectures over extended distances where standard copper cabling is impractical or susceptible to electromagnetic interference.

This unit provides reliable conversion between electrical Ethernet signals and optical signals, ensuring secure communication across distributed plant floors and control rooms. The module is built to withstand demanding industrial environments, featuring rugged construction and standard rail-mounting capabilities designed for integration within control cabinets and marshaling panels.

Features

• Enables long-distance optical communication for industrial control networks
• Converts standard electrical signals to high-integrity fiber optic transmission
• Designed for integration within Honeywell automation and DCS architectures
• Diagnostic LED indicators for power, link status, and network traffic monitoring
• Standard industrial form factor for efficient DIN-rail or panel mounting
• Galvanic isolation between field networks to prevent ground loop issues

Applications

• Distributed Control System (DCS) network backbone extension
• Inter-cabinet communication in large manufacturing plants
• Data transmission across high-interference electrical sub-stations
• Remote I/O drop connection over extended industrial ranges
• Process automation facilities requiring secure, long-span networking

Installation Guidelines

1. Verify that the part number 8937-HN2 matches system engineering requirements and documentation.
2. Ensure all power sources to the cabinet and target backplane are de-energized before handling hardware.
3. Inspect the module and optical connectors for dust, scratches, or physical damage prior to installation.
4. Mount the module securely onto the designated DIN rail or panel location.
5. Clean fiber optic patch cables and connectors according to industry standards before inserting them into the module ports.
6. Connect the electrical network cables and DC power supply wiring to the appropriate terminals with correct polarity.
7. Restore power and observe diagnostic LEDs to verify successful communication link establishment.
