Product Description
The ABB NTAI03 is an analog input termination unit designed to integrate seamlessly into the Bailey INFI 90 DCS system. This unit provides a reliable interface for connecting field wiring from 100 Ohm Platinum RTD sensors to the IMASM03 Analog Slave Module. It is capable of accommodating up to two IMASM03 modules and can process up to 16 three-wire RTD input signals.
The NTAI03 unit ensures signal integrity by offering secure wiring, proper grounding, and reliable analog signal transmission for critical industrial applications. Though the NTAI03 has been replaced by the NTAI04, it remains an essential component in systems that require stable and accurate analog input signal processing, such as in power generation, oil & gas, chemical plants, and pulp & paper industries.
