Overview
The ABB NTU-7C9 Termination Unit plays a vital role in distributed control systems by serving as the connection bridge between field instrumentation and DCS I/O modules. Designed for ABB Bailey INFI 90 and Net 90 platforms, it simplifies signal wiring while maintaining electromagnetic compatibility and signal integrity.
Moreover, the NTU-7C9 supports analog and digital signal types, including 4–20 mA current loops and 0–10 V DC voltage signals. It features integrated shield grounding to reduce electrical noise and improve system stability. Additionally, its modular design allows for DIN rail or panel mounting, offering flexibility in installation across various industrial environments.
This termination unit is especially valuable for maintaining and upgrading legacy systems. Therefore, it remains a trusted component in facilities where ABB Bailey DCS platforms are still operational.
