Honeywell MU-FOED02 51197564-200 Universal Control Network (UCN) Fiber Optic Extender

Description

To establish long-distance, interference-free communication within Honeywell process control architectures, the Honeywell MU-FOED02 (part number 51197564-200) functions as a dedicated Universal Control Network (UCN) Fiber Optic Extender. This industrial module extends the physical reach of a standard coaxial UCN segment up to a distance of 2 kilometers, utilizing fiber optic cabling to ensure signal integrity across expansive plant installations. By translating electrical control signals into optical pulses, this device isolates electrical noise, eliminates ground loops, and protects critical control paths in high electromagnetic interference (EMI) environments.

Features

• Extends Universal Control Network (UCN) communication links up to a maximum distance of 2 kilometers.
• Provides optical isolation to prevent electrical noise propagation and ground loop currents.
• Maintains deterministic real-time communication protocols without signal degradation.
• Designed for integration into Honeywell TDC 3000 and TPS control system environments.
• Operates on a standardized 24 VDC industrial power input.

Applications

• Distributed Honeywell TDC 3000 control system network links.
• Power generation facilities requiring signal run extensions between control buildings.
• Chemical processing and oil and gas refineries with high electrical noise profiles.
• Long-distance plant network expansions connecting remote I/O sub-systems.

Technical Specifications

Installation Guidelines

• Install the module securely inside an IP-rated enclosure or standard system cabinet to protect against moisture and particulate contamination.
• Maintain appropriate fiber optic cable bend radiuses during routing to prevent signal attenuation and physical micro-fractures in the glass core.
• Confirm transmitter (TX) and receiver (RX) fibers are correctly paired and aligned before powering up the network segment.
• Connect the dedicated 24 VDC power supply utilizing properly shielded and grounded copper wiring.
