Overview
The ICS TRIPLEX T8449 is a Trusted TMR 24 Vdc Valve Monitor Module designed for controlling and monitoring field devices with high reliability and fault tolerance. It supports 20 output channels and 20 feedback input channels in a Triple Modular Redundant (TMR) architecture, ensuring robust performance for valve control systems. The module provides advanced diagnostics, real-time monitoring, and safety features critical for industrial applications.
Key Features
- Triple Modular Redundancy (TMR): All input and output channels operate in TMR mode for maximum fault tolerance.
- Field Device Monitoring: Tracks valve status using limit switches, travel times, and test status signals.
- Advanced Diagnostics: Active valve testing and automatic line monitoring detect faults such as open circuits, shorts, and wiring issues.
- Safety Features:
- Automatic over-current protection (no external fuses required)
- 2500 V impulse withstand isolation barrier
- Electronic short-circuit protection
- Hot-Replaceable: Can be replaced online using standby or SmartSlot configuration.
- Sequence of Events (SOE): On-board reporting with 1 ms resolution.
- LED Indicators: Show output status, feedback status, field wiring faults, module health, and operational mode.
- Certifications: TÜV Risk Class 6; CE marked; UL/cUL approved; DNV certified for marine/offshore.
- Non-Hazardous Area: Requires external intrinsic safety barrier for hazardous environments.
