ABB NTAI16-A 16-Channel Analog Input Termination Unit
I. Product Overview
The ABB NTAI16-A is a Universal Analog Input Termination Unit (also known as a termination board) in the ABB (formerly Bailey Controls) INFI 90 Distributed Control System (DCS). This module provides 16 universal analog input channels, supporting the connection and termination of various analog signal types, and is an important component for field analog signal acquisition and processing in the INFI 90 system.
The NTAI16-A supports ±10V DC voltage input, 4-20mA current input, and resistance input, employing a 12-bit or higher precision A/D converter to ensure accurate signal acquisition. The module features channel-to-channel and channel-to-ground electrical isolation, effectively suppressing common-mode interference and ground loop effects. Operating voltage is 24V DC, with IP20 protection rating, suitable for installation on field termination panels (NFTP01) inside control cabinets. Widely used in industrial process control fields such as power, petrochemical, metallurgy, paper, and water treatment.
