Product Overview

The ABB NTLS01 Logic Station Terminal Unit is a core interface module in ABB distributed control systems (DDCS / Network 90 / DCS) and industrial automation systems.
It provides the interface between the logic station and the control system, managing digital and analog signals centrally and ensuring terminal matching, enabling stable and reliable data communication between logic processing modules and field I/O modules.
The NTLS01 features modular design, clear status monitoring, strong interference immunity, and easy installation and maintenance, making it an essential logic interface component in industrial automation systems.

Technical Specifications

Advantages & Features

1. Centralized logic signal management – Supports centralized access and distribution of digital/analog signals, improving system efficiency.

2. High reliability and interference immunity – Optical or electrical isolation ensures stable signals, preventing interference and ground loops.

3. Modular design – Plug-in design allows easy installation, maintenance, and system expansion.

4. Clear status monitoring – LEDs indicate power, communication, and fault status for easy field maintenance.

5. Industrial-grade stability – Suitable for complex industrial temperature and humidity environments for long-term operation.

6. Easy installation and maintenance – Plug-in module allows quick installation and removal, improving field efficiency.

Application Areas

• Industrial automation control systems

• Distributed control systems (DDCS / DCS)

• Logic station and control system interface terminals

• Power plants, petrochemical, chemical, and mining automation systems

• Production line logic control and signal management

• Water treatment and environmental system logic signal interfaces

Installation & Operation Notes

1. Mounting environment – Install in a dry, ventilated, dust-free cabinet; avoid high temperature and humidity.

2. Wiring – Use industrial standard wires; ensure terminals are securely connected to prevent poor contact.

3. ESD protection – Wear an anti-static wrist strap during installation or maintenance.

4. Signal cable routing – Input/output signal cables should be routed separately from high-voltage power lines; shielded twisted-pair cable recommended.

5. Periodic inspection – Check terminal tightness and LED status to ensure stable logic signal transmission.
