Description

The ABB Bailey Infi 90 NTCF21 is a fiber-to-fiber termination unit designed to interface PCU communication modules (such as the NIS or NPM) with fiber optic media. This unit is a critical component for long-distance communication within the INFI-Net control network, enabling reliable data transmission across fiber optic infrastructure. The NTCF21 supports direct connection of 62.5-micron fiber optic cables for both transmit (TX) and receive (RX) functions.

Features

• Designed for Bailey Infi 90 control systems.
• Fiber-to-fiber communication interface for long-distance network extension.
• Supports 62.5-micron multi-mode fiber optic cabling.
• Compatible with PCU communication nodes (NIS/NPM).
• Provides robust data transmission in industrial environments.

Applications

• Power Generation: Linking area controllers and remote I/O in coal, gas, and renewable energy plants.
• Water & Wastewater: Supporting SCADA networks for monitoring distributed transmission and distribution assets.
• Oil, Gas & Petrochemical: Providing reliable communication for flow computers and control racks.
• Manufacturing: Synchronized block control for chemical, pulp, paper, and pharmaceutical processing.
• Mining & Metals: Rugged communication solutions for high-vibration and high-EMI environments.

Technical Specifications

Installation Guidelines

• Ensure the unit is mounted in a clean, dry environment protected from excessive dust and moisture.
• Verify that fiber optic connectors are clean before insertion to prevent signal attenuation.
• Maintain the minimum bend radius for all fiber optic cables to avoid signal loss or physical damage.
• Secure the unit using the designated mounting screws to ensure proper grounding and EMC compliance.
• Power down the system before installing or removing the module from the communication bus.
• Route fiber optic cables away from high-voltage power lines to minimize potential interference.

FAQs

What is the ABB NTCF21?
