Product Details
Description
The ABB NTAI02 is a dedicated Analog Input Termination Unit engineered for the Bailey Infi 90 and Network 90 Distributed Control Systems (DCS). This unit functions as the physical junction point where field transmitter signals are landed and routed to the system's Analog Input Slave modules. It is designed to handle up to 16 channels of analog data, supporting standard industrial signal ranges such as 4-20 mA and 1-5 VDC. By providing a structured termination environment, the NTAI02 ensures high signal fidelity and simplifies the complexity of field-to-control room wiring. Its robust electrical design includes provision for shunt resistors, allowing for versatile current-to-voltage conversion directly at the terminal level.

Tech & Buying Guide
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
