ABB NTAI02 Bailey INFI 90 Analog Input Termination Unit
The ABB Bailey NTAI02 is a 16-channel analog input termination unit designed for the Bailey INFI 90 Distributed Control System (DCS). It marshals thermocouple and millivolt signals directly from field sensors and routes them to IMASM02 Thermocouple Slave Modules, which subsequently interface with IMAMM03 Analog Master Modules for processing.
Architecture and Module Pairing
Each NTAI02 unit provides connection points for up to 16 analog input channels. To scale input density within a system cabinet, up to four NTAI02 termination units can be connected to a single IMASM02 slave module. This modular topology streamlines cabinet cable management and simplifies point-to-point field wiring for high-density temperature and millivolt monitoring.
Mechanical and Custom Regulatory Data
Designed for panel or rack mounting inside industrial control enclosures, the termination unit measures 7.62 cm x 35.6 cm x 25.4 cm (3.0 in x 14.0 in x 10.0 in) and weighs 0.5 kg. It is classified under HS Code 85389081, with manufacturing locations including Sweden, Malta, or India depending on supply batch.
