Description

Product Overview

The ABB NTRL04 is a compact HNET Fiber Optic Repeater Termination Unit designed for Symphony Plus and Symphony Harmony DCS networks. It converts electrical HNET signals into optical channels to provide safe, long-distance data transmission. This module provides absolute electrical isolation, protecting control nodes from severe electromagnetic interference (EMI) and ground loops.

Core Technical Advantages

  • High-Speed Communication: Runs at a deterministic 4 Mbaud HNET data rate to ensure zero network lag.
  • High Network Capacity: Manages up to 12 devices per link and supports 6 redundant HNET drops.
  • Extended Range: Bridges remote enclosures up to 3,000 meters away via multimode optical fiber.

Installation & Engineering Guide

  • Fiber Care: Maintain a minimum 40 mm bend radius to prevent core cracks and signal loss.
  • Cabling: Use copper lines under 30 m; use 62.5/125 μm multimode fiber for distances up to 3,000 m.
  • Power: Input must stay strictly between 21.6 VDC and 28.0 VDC to safeguard internal circuitry.
  • Redundancy: The unit automatically routes data to the secondary link if the primary line fails.

Technical FAQs

Q1: What fiber type and connector does the NTRL04 require?
A1: It uses 62.5/125 μm graded-index multimode fiber at 840 nm with ST-style connectors.

Q2: What happens if the optical line exceeds 3,000 meters?
A2: Distance over 3,000 m causes attenuation beyond the -3.5 dB/km budget, leading to lost communication.

Q3: Can I run copper and fiber connections at the same time?
A3: Yes. Use copper for local paths under 30 m and fiber for long-range cabinet links up to 3,000 m.
