Product Title

ALSTOM UT150‑2 – Turbine Trip / Trip Amplifier Module

Product Overview

The ALSTOM UT150‑2 is a turbine protection and trip amplifier module used in industrial turbine control systems. It forms part of Alstom’s legacy control and protection platforms—often found in steam, gas, and hydro turbine installations—where rapid and reliable detection of critical conditions is essential for safe operation.

The module monitors key process signals such as overspeed, high vibration, and temperature limits. When a fault threshold is exceeded, the ALSTOM UT150‑2 generates trip signals to initiate protective shutdowns, minimizing equipment damage and supporting plant safety protocols. Its application in high‑risk environments helps ensure turbine integrity and operational continuity.

Designed for rugged industrial environments, the ALSTOM UT150‑2 integrates into control racks and interfaces with supervisory systems for real‑time protection, status reporting, and automatic shutdown execution.
