Brand New and original ICS Triplex T8442
Description
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. The speed input channels are designed to interface directly with a Trusted T8846 Speed Input Field Termination Assembly (SIFTA). A single T8846 provides signal conditioning and field cable termination facilities for the nine TMR speed input channels required for three rotating machine groups. Both active and passive speed probes can be accommodated by the T8846. Active probes can be powered from the field cable termination. The shutdown control outputs are designed to interface directly with three Trusted T8891 Speed Output Field Termination Assemblies (SOFTA). A single T8891 contains the two quad redundant, fault tolerant, volt-free contact structures required for a single rotating machine group. The inter-connections between the Module and the Field Termination Assemblies (FTAs) are provided by a Trusted TC-801 Cable Assembly.
