• Power: IEC C13 (120 VAC input)

• Status LEDs: Power, Link, Tx, Rx, Fault

• Switch Settings: Termination, fiber mode, station address

Core Functions

• Signal Conversion: Converts electrical UCN signals to optical for long‑distance transmission

• Noise Immunity: Eliminates EMI/RFI interference in industrial environments

• Distance Extension: Extends UCN reach from 500 m (copper) to 2 km (fiber)

• Network Isolation: Provides electrical isolation between UCN segments

• Diagnostics: On‑board LED indicators for link and fault status

Application Scope

• Honeywell TDC3000/TPS DCS (UCN network extension)

• Process industries: power, oil & gas, refining, chemical, petrochemical

• Control rooms and remote field units separated by >500 m

• Areas with high electrical noise (motors, VFDs, heavy machinery)

• Replacement of legacy UCN repeaters (51197564‑L00)

Operation & Maintenance Instructions

• Place in clean, ventilated area near UCN node or cabinet

• Connect RJ‑45 to UCN device; connect ST fiber to remote extender

• Apply 120 VAC power; verify “Power” and “Link” LEDs are lit

• Check “Tx/Rx” LEDs flash during data transfer; “Fault” LED off

• Keep ambient temp < 55 °C; avoid direct sunlight and moisture

• Replace only with Honeywell‑certified 51197564‑100 extenders
