Product Introduction
The ABB Bailey NCIS01 (6635169D1) is a Control I/O Slave Module designed for use in ABB’s proven INFI 90 Distributed Control System (DCS). Specifically developed to operate within critical process industries, this module plays a vital role in managing field-level input/output operations by acting as a slave processor to the main controller.
The NCIS01 interfaces with I/O channels, facilitating real-time data acquisition and control through high-reliability communication protocols. It helps distribute the I/O load and extend the system’s scalability, all while ensuring deterministic response to field signals.
Robust in design and optimized for demanding industrial environments, the NCIS01 is widely used in sectors such as power generation, petrochemicals, oil & gas, and water treatment. It supports both digital and analog I/O, enabling flexible configurations and integration with legacy and modern systems alike.
