Product Introduction
The Emerson is a SIL 3‑rated overspeed protection monitor for critical rotating machinery—turbines, compressors, generators. It uses dual‑channel sensor inputs and 1oo2/2oo2 voting to detect overspeed and trigger trips in <10ms.
This unit integrates into SIS and DeltaV DCS, supporting eddy current, Hall‑effect, and VR sensors. Its isolated power and wide temperature range ensure reliability in harsh oil/gas, power, and chemical environments.
