Description

T8480: Product Overview

The ICS Triplex T8480 is a Triple Modular Redundant (TMR) analog output module designed for safety-critical applications in industrial automation systems. As part of the Trusted TMR platform, this module plays a critical role in safety instrumented systems (SIS) by providing reliable analog output control for process control, emergency shutdown systems, and critical control applications.

The module interfaces with up to 40 field devices, handling analog output signals to control devices such as control valves, variable frequency drives, and positioners. Each output channel operates with triple modular redundancy, featuring three independent processing legs that vote on output decisions. This architecture ensures that a single component failure does not cause a dangerous failure of the safety function, making it suitable for Safety Integrity Level (SIL) 3 applications as certified by TÜV Rheinland.

Belonging to the Trusted TMR platform, the T8480 benefits from a fully triplicated architecture that provides fault tolerance through three independent processing legs. The module performs triplicated diagnostic tests throughout its operation, continuously monitoring both internal components and connected field wiring to detect faults before they can compromise safety functions.

Core Features & Customer Value

Triple Modular Redundant Architecture: The T8480’s TMR design provides three independent processing legs that vote on output decisions. For customers, this means the system can tolerate two simultaneous faults without causing a dangerous failure, significantly reducing the risk of spurious trips and unplanned downtime. This architecture delivers the highest availability among SIL3-rated safety systems, ensuring continuous operation even during component failures.

Comprehensive Diagnostic Capabilities: The module performs triplicated diagnostic tests throughout its operation, continuously monitoring both internal components and connected field wiring. This feature allows engineers to detect developing faults before they impact system safety, enabling proactive maintenance scheduling rather than reactive repairs. The module can identify open circuits, short circuits, and load faults, providing detailed diagnostic information through the front panel LEDs and system software.

High-Density Channel Configuration: With 40 analog output channels in a single module, the T8480 offers exceptional channel density that reduces system footprint and simplifies wiring. This high channel count allows engineers to consolidate multiple control points into a single module, reducing spare parts inventory and simplifying maintenance procedures. The module’s hot-swappable design enables replacement without system shutdown, minimizing production losses during maintenance activities.

Typical Applications

The T8480 is extensively deployed in safety-critical applications across the oil and gas, petrochemical, and power generation industries. In process control systems, this module provides precise analog control signals to control valves and final control elements, maintaining critical process parameters within safe operating limits. The module’s high accuracy (±0.05%) ensures precise control of flow rates, pressures, and temperatures in continuous processes.

In emergency shutdown systems, the T8480 activates critical shutdown valves and process isolation devices when hazardous conditions are detected. The module’s fast response time ensures that safety functions are executed within the required safety time constraints. In power generation plants, particularly combined-cycle and nuclear facilities, the module provides protection functions for turbine overspeed protection, boiler safety systems, and reactor protection systems.

The T8480 is also widely used in fire and gas detection systems, where it activates fire suppression systems, emergency ventilation, and alarm systems. The module’s SIL3 certification and TMR architecture ensure that shutdown commands are executed reliably even in the presence of component failures or harsh environmental conditions.
