The T8442 is a Trusted® Triple Modular Redundant (TMR) Speed Monitor Module designed for high‑integrity monitoring of critical rotating machinery. Its modular and fault-tolerant architecture ensures reliable operation even in harsh industrial environments.
Triple Redundancy
Fault-Tolerant Output
Self-Diagnostics
Equipped with triple redundant speed inputs and quad redundant shutdown outputs, the T8442 provides over-speed and over-acceleration protection for turbines, pumps, compressors, and generators. Its self-diagnostic and LED status indicators allow real-time health monitoring, enabling rapid fault detection and minimal downtime.

Oil & Gas Refineries
The module monitors high-speed rotating machinery in refinery processes, ensuring turbines and compressors operate within safe speed limits. It provides fault-tolerant shutdown in case of over-speed or abnormal acceleration events.
Chemical Processing Plants
Used to supervise pumps, mixers, and agitators in chemical plants, the system ensures safe operation under harsh conditions. Over-speed detection helps prevent mechanical failures and chemical spills.
Power Generation
Monitors turbines, generators, and auxiliary equipment in power plants. Protects machinery from damage due to over-speed or abnormal acceleration.
Water & Wastewater Facilities
Provides safety monitoring for high-speed pumps, mixers, and aeration blowers. Prevents mechanical damage and ensures reliable operation in critical water treatment processes.
Marine & Offshore Platforms
Used for turbine, pump, and compressor monitoring on ships and offshore oil rigs. Protects critical rotating equipment in harsh marine environments.
Pulp & Paper Mills
Monitors high-speed machinery such as paper machines, pumps, and refiners. Ensures safe operation by detecting over-speed conditions and providing automated shutdown.
The ICS Triplex T8442 employs a Triple Modular Redundant (TMR) architecture where each rotating machine group includes three identical TMR speed input channels and quad‑redundant, fault‑tolerant shutdown output structures. This hybrid redundancy ensures the system continues to operate safely even in the presence of hardware faults, minimizing the risk of undetected failures in critical rotating machinery monitoring.
The ICS Triplex T8442 is a Trusted® Triple Modular Redundant (TMR) Speed Monitor Module designed for high‑integrity speed and acceleration monitoring of rotating machinery. It provides fault‑tolerant control functions including over‑speed and over‑acceleration shutdown protection.
What does the T8442 monitor?
The T8442 monitors shaft speed and acceleration signals from rotating machines such as turbines driving pumps, compressors, and generators. It helps ensure machinery operates within safe speed limits and triggers shutdown if unsafe conditions occur.
How many machines can one T8442 support?
A single T8442 module includes three monitoring and control groups, each capable of independently handling speed monitoring and shutdown control for one rotating machine, allowing up to three turbine trains per module.
What redundancy features does the T8442 have?
The T8442 uses Triple Module Redundant (TMR) speed inputs and quad redundant, fault‑tolerant shutdown output structures to ensure high availability and fail‑safe performance even when individual components fail.
What diagnostics and status indicators are available on the T8442?
The T8442 provides comprehensive automated diagnostics and self‑test functions, and includes front panel LEDs that indicate module health, operating mode, and input/output status for each rotating machine group.
