ICS Triplex T8442 TMR Speed Monitor Module Ready to Ship

The ICS Triplex T8442 is a Trusted TMR Speed Monitor Module. It is part of the ICS Triplex Trusted TMR Safety System, which is a high-availability, high-reliability safety system designed for use in critical applications.

The T8442 monitors the speed of rotating shafts and provides a reliable signal to the ICS Triplex Trusted TMR Safety System if the speed falls below a safe threshold. This can be used to trigger an emergency shutdown or other protective measures.

Key features:

• Hot-swappable modules for easy maintenance and repair

• Online diagnostics to detect and isolate faults

• Wide operating temperature range

• High vibration and shock resistance

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.
