Overview
The ABB Bailey NTU‑7UO (NTU7UO) and NTU‑7U0 (NTU7U0) are termination units designed to handle analog input/output signals in ABB’s Infi‑90 DCS.
These modules provide electrical isolation between field devices and the control system, preventing interference and ensuring accurate signal transmission.
They are widely used in process industries, power generation, and utilities, where precise analog measurements (temperature, pressure, flow, level) must be transmitted without distortion or noise.
