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.
