Product Overview

The SPTPS13 is a specialized, high-performance Turbine Protection and Termination Power Supply module designed for the ABB Symphony Plus (S+ HR) and Harmony Rack I/O systems. Engineered specifically for the rigorous demands of steam and gas turbine control, the SPTPS13 acts as a critical hardware interface between field-side sensors and the central control logic. It serves a dual role: providing stable, regulated 24 VDC power to subordinate I/O modules while facilitating secure signal termination for protection-critical field devices. By delivering real-time monitoring and rapid fault response, this module ensures system integrity and minimizes the risk of mechanical damage in utility-scale and industrial power generation environments.
