ICS TRIPLEX T8193 Safety System Power Supply

Product Description

The ICS TRIPLEX T8193 is a high-integrity, hot-swappable power supply module designed for the ICS Triplex Trusted (Triconex) fault-tolerant safety and critical control systems, now part of Emerson. This module is engineered to provide clean, regulated, and redundant DC power to the critical components of a Trusted system, such as the main processors and I/O modules within a chassis. Its primary function is to ensure the highest possible availability of the safety instrumented system (SIS) by eliminating single points of failure in the power delivery path. The ICS TRIPLEX T8193 is built to the stringent reliability standards required for applications where continuous operation is mandatory, such as in offshore platforms, refineries, and power generation facilities. For comprehensive technical specifications, safety manuals, and installation guidelines, please visit the official product resource: ICS TRIPLEX T8193. The integration of the T8193 power supply is a foundational element in building a high-availability Trusted system, providing the stable electrical foundation upon which the Triple Modular Redundant (TMR) architecture depends. Proper operation of the ICS TRIPLEX T8193 is critical for maintaining the overall health and safety certification of the control system.

Product Parameters

• Product Model: ICS TRIPLEX T8193
• System Platform: ICS Triplex Trusted (Triconex) Safety System.
• Module Type: Hot-Swappable, Redundant Power Supply Unit.
• Input Power: Typically accepts a wide-range AC input (e.g., 90-264V AC, 47-63 Hz) or sometimes a DC input, converting it to regulated low-voltage DC outputs.
• Output Power: Provides specific DC voltage rails (e.g., +5V, ±12V, +24V) required by the Trusted controller and I/O modules within its chassis.
• Redundancy: Designed for N+1 or 1:1 redundant configuration. Multiple T8193 modules share the load, and the system can continue operating normally if one module fails.
• Hot-Swap Capability: Can be inserted or removed from a powered and operating system without disrupting the control functions, enabling maintenance without a system shutdown.
• Load Sharing: Modules operating in parallel actively share the total load current evenly.
• Diagnostics and Alarming: Features comprehensive status LEDs (Power OK, Fail, Load Share) and provides discrete alarm contacts to signal power supply failure to the control system.
• Cooling: Typically includes an internal cooling fan.
• Mounting: Installs into a dedicated power supply slot in a Trusted system chassis or cabinet.
• Safety Certification: Designed for use in critical systems, though the power supply itself is part of the overall safety system’s certification to standards like IEC 61508.

Advantages and Features

• High Availability through Redundancy: The ability to operate in a redundant, load-sharing configuration ensures continuous system operation even after a power supply failure, which is paramount for safety systems.
• Maintenance Without Downtime: The hot-swap feature allows for the preventive replacement or repair of a power supply module without requiring a process shutdown or taking the safety system offline.
• Excellent Power Quality: Provides tightly regulated, low-noise DC power, which protects sensitive controller electronics from voltage transients and ensures stable, deterministic system operation.
• Robust and Reliable Design: Built with high-quality industrial components and designed for 24/7 operation in environments with temperature fluctuations and electrical noise.
• Comprehensive Diagnostics: Clear local indicators and remote alarm contacts provide immediate notification of any power supply issue, allowing for rapid response.

Application Cases in Various Fields

• Oil & Gas Offshore Emergency Shutdown (ESD): Provides redundant power to the main Tricon controller chassis that executes the platform’s ESD logic, ensuring the safety system remains powered during electrical disturbances.
• Chemical Plant Burner Management System (BMS): Powers the TMR controllers that manage the critical start-up and shutdown sequences for large industrial furnaces, where loss of power could lead to a hazardous condition.
• Power Generation Turbine Control: Supplies clean, reliable power to the safety controllers that protect gas or steam turbines from overspeed and other dangerous conditions.
• Pipeline Compressor Station Safety: Ensures the continuous operation of the safety system monitoring and protecting critical compressor units along a gas transmission pipeline.

Comparison with Competing Products

The ICS TRIPLEX T8193 competes with redundant power supplies from other high-availability safety system vendors like HIMA and Siemens. Its primary advantage is its certified, seamless integration within the Trusted/Triconex TMR ecosystem. Unlike generic industrial redundant power supplies, the T8193 is mechanically and electrically designed to fit the specific Trusted chassis, includes the necessary communication for load sharing and diagnostics, and is validated as part of the overall safety system. It represents a specialized, system-integrated component rather than a standalone commodity power supply.

Selection Suggestions and Precautions

1. System Compatibility Verification: It is essential to confirm that the ICS TRIPLEX T8193 is the correct and compatible power supply for your specific Trusted chassis model (e.g., T8110, T8310) and controller generation.
2. Redundancy Configuration: For high-availability applications, always deploy the power supplies in the recommended redundant configuration (e.g., two or three modules). Ensure they are properly connected for load sharing as per the system installation manual.
3. Input Power Source Quality: While tolerant of a wide input range, connect the power supplies to a stable, clean power source. Using an Uninterruptible Power Supply (UPS) for the AC feed is a best practice for critical safety systems.
4. Cooling and Ventilation: Ensure the chassis or cabinet has adequate airflow. Do not obstruct the air intake or exhaust of the T8193 modules, as overheating will reduce their lifespan and can cause failure.
