The ABB Bailey NTRL03 (6637359K2) is a robust and reliable Remote I/O Module designed for use in ABB’s INFI 90 and Symphony distributed control systems (DCS). Engineered to extend the control system’s reach, the NTRL03 enables remote signal acquisition and control by interfacing with field input/output devices while maintaining synchronized communication with the central processor.

This module is critical for large-scale process automation environments where decentralization is required due to physical plant layout. The NTRL03 facilitates real-time data collection, digital/analog signal handling, and supports high-integrity communication through ABB’s proprietary control network protocols. Built for high performance and long-term stability, it is widely deployed in mission-critical process industries including energy, petrochemicals, and utilities.
