The ABB NIAI04 Analog Input Termination Unit is a key interface module in ABB distributed control systems (DDCS / Network 90) and industrial automation systems.
It receives analog signals (voltage or current) from field sensors, processes the signals, and transmits them to the main control system for data acquisition and monitoring.
The NIAI04 features high precision, stability, and strong interference immunity, making it widely used in industrial automation, process control, and energy management systems.
