Overview

The ABB NIAI04 is an essential termination unit designed for distributed control systems (DCS), responsible for routing analog signals from field devices (such as transmitters and sensors) to corresponding analog input modules like the IMASI02 or IMASM01. It simplifies wiring, enhances signal integrity, and supports both differential and single-ended inputs, making it highly versatile.

The NIAI04 accommodates a wide range of analog signal types, including current and voltage inputs. It features a compact, rack-mountable design and offers compatibility with various cable types, which further improves the flexibility of installations. Additionally, the module can be powered either system-powered or via an external power source, providing more installation options.

With its precise analog signal handling, the NIAI04 is commonly used in power generation, chemical processing, and water treatment applications, where reliable and scalable analog signal routing is crucial.

Technical Data

Typical Applications

The NIAI04 is widely used in ABB INFI 90 and Symphony Plus control systems for managing the routing of analog signals. Specific applications include:

• Power Plants and Refineries: It connects pressure, temperature, and flow transmitters to analog input modules, ensuring accurate signal transmission for control and monitoring.

• Water Treatment Facilities: Used in environmental monitoring systems to route analog signals from field devices to the central control system.

• Manufacturing and Process Control: Supports process control loops in industries where precision and flexibility in signal routing are essential.

The flexibility in signal types and the modular design of the NIAI04 also make it ideal for both retrofit projects and new installations, especially when dealing with multiple types of analog signals.
