Emerson Emergency Shutdown Discrete Valve Controller

Emerson has introduced the TopWorxTM DX PST with HART 7. Units provide valuable valve data and diagnostic information, enabling the digital transformation of process applications. The new DX PST integrates seamlessly with existing valves and control systems, giving operators access to critical valve data, trends, and diagnostics that can be used to predict and schedule maintenance. The DX PST’s partial stroke test ensures the system’s reliable function without shutting down the process. A safety feature that confirms the valve will fully close and stop the process if an emergency is detected, and the test is activated by simply pressing the local PST button — no additional equipment is required.
