Product Description
High-Integrity Relay Interface for Symphony Plus
The ABB NTRO12-A (also identified as NTR012-A) is a specialized Relay Output Termination Unit engineered for the Symphony Plus and INFI 90 Distributed Control Systems (DCS). This module serves as the primary physical and electrical interface between the system's digital output modules and field actuators. Unlike standard passive termination units, the NTRO12-A is designed to facilitate the routing and distribution of control signals to relay-based field devices, ensuring that logic-level signals are safely and reliably translated into mechanical or high-current actions.
Robust Engineering and Signal Isolation
The NTRO12-A provides a structured wiring platform that simplifies cabinet density while maintaining strict electrical isolation between the system bus and field-side power. It features high-quality screw-type terminal blocks that ensure low-resistance connections for both analog and digital signaling paths. This termination unit is critical for protecting sensitive controller electronics from potential transients and surges originating in the field. Its industrial-grade construction and integrated circuit board design provide high noise immunity, which is essential for stable operation in EMI-heavy environments such as power plants and chemical refineries.
