Description
The T8891C Trusted Speed Monitor Output Field Termination Assembly (FTA) is a DIN-rail mounted interface module designed for high-reliability industrial speed monitoring systems. It provides a safe and flexible field output interface for rotating machinery protection within Triple Modular Redundant (TMR) architectures.
Applications
Hydropower Plants: Controls turbine trip systems during overspeed events.
Oil Refineries: Manages emergency shutdown for compressor systems.
Gas Stations: Controls remote turbine and pipeline safety systems.
Metal Smelters: Provides trip control for mills and blowers.
Marine Chemical Plants: Ensures shutdown logic in harsh offshore environments.
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.
