ICS TRIPLEX T8449 Trusted TMR 24 Vdc Valve Monitor Module

The Rockwell Automation ICS TRIPLEX T8449 Trusted TMR 24 Vdc Valve Monitor Module is designed for controlling and monitoring field devices with high reliability and fault tolerance. It interfaces with 20 field devices, each controlled via an output channel and monitored through a separate input channel. The module operates with a Triple Modular Redundant (TMR) architecture, ensuring robust fault tolerance and reliability. It is ideal for valve control systems where advanced diagnostics, real-time monitoring, and safety are critical.

Product Overview

Module Type: Trusted® TMR 24 Vdc Valve Monitor
Channels: 20 output points and 20 feedback input points (Triple Modular Redundant).
Field Device Monitoring: Monitors valve status through limit switches, travel times, and test status.
Diagnostic Capabilities: Advanced diagnostics and active valve testing, with automatic line monitoring to detect faults such as open circuits, short circuits, and wiring issues.
Fault Tolerance: Triple Modular Redundant (TMR) design for all input and output channels.
Safety Features: Includes automatic over-current protection (no external fuses needed), 2500 V impulse withstand isolation barrier, and electronic short circuit protection.

Additional Features

Hot-Replaceable: Can be replaced on-line with a standby slot or SmartSlot configuration.
Sequence of Events (SOE): On-board SOE reporting with 1 ms resolution.
LED Indicators: Front panel LEDs for output status, feedback status, and field wiring faults.
Module Status: LEDs for module health and operational mode (Active, Standby, Educated).
TÜV Certified: Risk Class 6 certification for safety and reliability.
Non-Hazardous Area: This module is not approved for direct connection to hazardous areas; an intrinsic safety barrier is required.
