Application Scenarios
Deploy the NTCF23 in process control installations where electrical noise, ground loops, or extended cable runs compromise signal quality. Ideal for petrochemical facilities, power generation plants, water treatment systems, and manufacturing operations requiring deterministic network performance across electrically isolated zones. The fiber optic conversion extends network reach beyond copper limitations while maintaining microsecond-level response times critical for real-time control.
Integration Solutions
This termination unit integrates directly with INFI-Net network infrastructure, pairing with the NTCF22 Optic-to-Electric TU to establish complete fiber optic links. Compatible with INICT13A Computer Transfer Modules and NTAI02 Termination Units for comprehensive system architecture. Supports redundant network topologies when configured with dual fiber paths.
Common Questions
Q: What fiber optic cable types are supported?
A: The NTCF23 accepts standard multimode fiber optic cables with ST or SC connectors, supporting transmission distances up to 2 kilometers depending on fiber quality and network configuration.
Q: Can this unit operate in hazardous area classifications?
A: While the NTCF23 itself is designed for industrial environments, deployment in Division 1 or Zone 1 hazardous locations requires appropriate enclosures and certifications. Consult your system integrator for compliance verification.
Q: Is hot-swapping supported during operation?
A: Network topology and redundancy configuration determine hot-swap capability. Redundant network designs allow module replacement without process interruption, while single-path configurations require controlled shutdown procedures.
Q: What diagnostic capabilities are included?
A: Front-panel LEDs provide real-time indication of power status, optical transmit activity, and receive signal strength. Advanced diagnostics are accessible through INFI-Net configuration software for signal quality monitoring and fault isolation.
