ABB NTAI06 Symphony Harmony INFI 90 Universal Analog Input Termination Unit
Product Overview
The ABB NTAI06 is a professional-grade Universal Analog Input Termination Unit (TU) engineered for the Symphony Harmony and INFI 90 distributed control systems (DCS). It serves as the physical interface between field wiring and the system's analog input modules, such as the IMASI23. Designed to handle up to 16 channels, the NTAI06 supports a diverse range of signal types including 4-20 mA current loops, high-level voltages, millivolt signals, thermocouples, and RTDs. This unit ensures signal integrity through high-accuracy components and robust galvanic isolation, making it a critical component for high-reliability process control in power generation and heavy industrial sectors.
