Product Overview

The ABB NTAI06 functions as a high-density Universal Analog Input Termination Unit (TU) specifically designed for Symphony Harmony and INFI 90 Distributed Control Systems (DCS). This unit bridges the gap between field-side sensors and system-level analog input modules, such as the IMASI23. It accommodates up to 16 universal channels, allowing for the simultaneous integration of current loops, thermocouples, and RTDs within a single footprint. We offer this unit as 100% Brand New and original equipment, providing the structural and electrical integrity required for power generation and heavy industrial process control.

Engineering Advantages

The NTAI06 streamlines complex field wiring and enhances system reliability through a hardware-first design optimized for harsh industrial environments.

Universal Signal Versatility: The NTAI06 eliminates the need for multiple specialized boards. By supporting 4-20mA current loops alongside millivolt and thermocouple signals on the same unit, it reduces spare parts inventory and simplifies cabinet design.
Superior Signal Integrity: High-performance components provide a 120 dB common-mode rejection ratio. This ensures that the NTAI06 filters out electromagnetic noise and interference common in heavy industrial settings, delivering clean data to the processor.
Extreme Environmental Resilience: Unlike standard commercial interfaces, the NTAI06 operates across a broad temperature range from -40 °C to +70 °C. This makes it suitable for unconditioned remote instrument enclosures or high-heat power plant environments.
Galvanic Protection: 2000 V RMS input isolation shields your expensive DCS control modules from field-side electrical surges and ground loops, preventing catastrophic system failure and minimizing downtime.

FAQs

Which ABB modules are compatible with the NTAI06?

The NTAI06 primarily interfaces with the IMASI23 Analog Input Module. It uses standard ABB ribbon cables to connect field signals directly to the input module in the Harmony rack.
Can the NTAI06 handle mixed signal types simultaneously?

Yes. The universal nature of the 16 channels allows you to mix 4-20mA signals, thermocouple inputs, and RTDs on a single board, provided you configure the corresponding input module correctly in the software environment.
Does the NTAI06 require external power for the 4-20mA loops?

The NTAI06 manages signal termination, but loop power requirements depend on whether you use the internal DCS power or an external source. The board provides the necessary terminal points to facilitate both configurations.
Is this a Brand New unit?

We guarantee that every ABB NTAI06 unit we supply is 100% Brand New and original. We do not sell refurbished or "pulled" hardware for safety-critical DCS applications.
