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.
