The ABB Bailey NIAI05 Analog Input Termination Module is a high-density signal interface component used in the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It is designed to terminate and route multiple analog input signals from field instruments into the system’s universal analog slave modules.
In real industrial applications, the NIAI05 acts as a structured wiring and signal interface layer. It ensures that analog signals such as voltage, current, RTDs, and thermocouples are correctly conditioned and safely transmitted to downstream processing modules. This improves system accuracy, reduces wiring complexity, and enhances long-term signal stability.
Each NIAI05 typically works in pairs with analog slave modules, supporting up to 16 input channels in total system configuration, making it a widely used solution in complex process automation environments.
