Core Operations Guide
Features:
- Two online tested, fault tolerant, volt free contact output channels.
- Each output can be used as either a normally open or a normally closed contact.
- Fault tolerant quad redundant output relay structure.
- Load feedback monitoring.
- Contact status feedback.
- Force guided contact, safety relays.
- Standard DIN Rail mounting.
- Each output rated.
- Relays, fuses and current sensors can all be replaced in situ.
The two relay output channels are arranged as quad redundant, fault tolerant structures. Failure ofany one relay or contact will not affect the load, or the ability to control the load.Load current feedback to the T8442 Speed Monitor is provided for each switching path on eachchannel.Force guided contact safety relays are used. These allow the T8442 Speed Monitor to detect weldedor stuck output contacts via the contact status and load current feedback from the SOFTA.Each relay, fuse and current-sensor can be replaced in situ.
The T8442C ICS Triplex Trusted Speed Monitor Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
A single Trusted T8442 TMR Speed Monitor interfaces with three T8891 SOFTA assemblies.A single SOFTA assembly provides the relay switching elements for one over-speed outputand one over-acceleration output.For each output channel, an isolated Hall Effect current sensor is connected in series witheach of the two parallel contact switching paths. The outputs from these sensors connect tothe T8442 via the TC801 field interface cable and are used for relay contact diagnostic andfault detection purposes.Force guided contact, safety relays are used on the SOFTA assembly. The physical propertiesof these relays verify that welded primary contacts can be detected by monitoring theauxiliary contact status signal. The contact status signal is passed back to the T8442 via theTC801 field interface cable for diagnostic and fault detection purposes.The output contact can be used as a normally-open (de-energized relay) or anormally-closed (de-energized relay) contact for connection to the field load. They areelectrically isolated from all other signals on the T8891 SOFTA and T8442 Speed Monitor.
- Turbine Control & Monitoring:Monitors up to 3 turbine trains using TMR speed inputs with SIFTA.
- Oil & Gas Industry:Used in exploration, production, refining, and critical machinery.
- Power Generation:Monitors turbine speed in power plants to ensure safety.
- Safety Shutdown Systems:Speed monitoring for SIL3 emergency shutdown systems.
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Module Insertion & Removal: The T8442 is designed for hot replacement, meaning it can be swapped while the system is powered.
Anti-Static Precaution: Modules contain sensitive components; always observe anti-static procedures when handling.
SmartSlot Support: Supports "one-to-many" hot replacement configurations to maintain system availability during a fault.
I/O Architecture: It functions as a triplicated module with 2oo3 (2-out-of-3) internal voting logic. It interfaces with field devices via a Trusted T8846 Speed Input Field Termination Assembly (SIFTA).
FAQs
-
What is the T8442C?
+It is a TMR Speed Monitor Module used in Trusted TMR systems to monitor rotational speed, providing safety-critical inputs. -
What is the function of the T8442C module?
+It is a TMR Speed Monitor module used to monitor field devices (e.g., speed sensors) in safety-critical applications. -
What is Triple Modular Redundancy (TMR)?
+This architecture uses three independent processing lanes to perform the same operation simultaneously. The system "votes" on the results to ensure accurate, fail-safe operation even if one lane fails. -
