Typical Machinery ICS Triplex T8442 Trusted TMR Speed Monitor AB Rockwell

ICS Triplex T8442

The Trusted® T8442 TMR Speed Monitor monitors the shaft speed and acceleration of rotating machinery. It provides machine protection for over-speed and over-acceleration shutdown functions. Typical machinery applications include steam and gas turbines driving pumps, compressors and generators. A T8442 Speed Monitor Module within a Trusted System provides the capability to perform turbine speed control independent of the machinery protection functions.

System response times are often critical for these types of application. To minimize processing delays the T8442 operates as a self-contained fault tolerant control sub-system within the Trusted System environment.

Each T8442 has three monitoring and control groups. Each group provides the Speed Monitoring and shutdown control facilities required for one rotating machine. Up to three turbine trains can be handled by a single T8442. A single rotating machine group comprises of three separate Triple Modular Redundant (TMR) speed input channels and two separate quad redundant, fault tolerant output drive structures. Turbines having more than three speed pickups can be accommodated by combining monitoring and control groups.
