ICS TRIPLEX T8193

Description

Product Overview: The ICS TRIPLEX T8193 Power Supply Module

The ICS TRIPLEX T8193 is a critical, high-integrity Triple Modular Redundant (TMR) power supply module engineered specifically for the Tricon and Trident Safety Instrumented Systems (SIS) by ICS Triplex, a part of Schneider Electric. Its fundamental role is to provide clean, regulated, and fault-tolerant DC power to the entire TMR controller chassis, including the main processors, I/O modules, and communication cards. As the heart of the system’s power distribution, the reliability of the ICS TRIPLEX T8193 directly impacts the availability and safety performance of the entire safety loop.

Detailed Product Parameters

• Product Type: TMR Power Supply Module.

• Compatibility: Designed for specific Tricon (e.g., v9, v10) and Trident chassis models. It is crucial to verify the exact chassis part number.

• Input Voltage: Accepts a range of input voltages, typically 120/240V AC or 125V DC, from the plant’s uninterruptible power supply (UPS) or secure power source.

• Output Power: Supplies multiple isolated and regulated DC voltage rails (e.g., +5V, ±12V, +24V) to power all modules within the chassis.

• Redundancy: Employs a TMR architecture internally, featuring three independent power conversion and monitoring circuits. The outputs are voted upon to ensure a single internal fault does not disrupt power to the controller.

• Hot-Swap Capability: Designed to be hot-swappable, allowing for replacement or maintenance without shutting down the safety controller, thus maximizing system uptime.

• Diagnostics & Monitoring: Comprehensive self-diagnostics with LED status indicators for input power, output health, and module faults. Fault status is communicated to the main processor.

• Certifications: Designed and tested for use in Safety Integrity Level (SIL) 3 applications, meeting rigorous standards such as IEC 61508.

Key Advantages and Distinguishing Features

The primary advantage of the ICS TRIPLEX T8193 is its fault-tolerant design, which eliminates the power supply as a single point of failure for the safety controller. Unlike a standard single or even redundant power supply, its internal TMR voting logic ensures continuous, clean power even in the event of a component failure within one of its three power circuits. This design philosophy is consistent across the Tricon platform. The hot-swap feature is critical for maintaining system availability during planned maintenance. The module’s robust diagnostics provide early warning of potential issues, allowing for proactive replacement. These features make the T8193 the cornerstone of a truly fault-tolerant control system’s infrastructure.

Typical Applications and Use Cases

This power supply is used wherever a Tricon or Trident safety controller is deployed for mission-critical shutdown or control functions. In offshore oil and gas platforms, the ICS TRIPLEX T8193 powers the Emergency Shutdown System (ESD) and Fire & Gas (F&G) system controllers that protect personnel and assets. In liquefied natural gas (LNG) plants, it ensures uninterrupted power to the safety controllers managing complex compression and cooling processes. Turbine control systems in power generation and critical compressor control in pipeline applications also rely on the absolute power reliability provided by this module. Any SIL 3 application utilizing a Tricon chassis depends on the T8193.

Comparison with Competing Power Supplies

Standard industrial power supplies, even those labeled as redundant, do not offer the same level of integrated fault tolerance as the ICS TRIPLEX T8193. A typical 1:1 redundant setup involves two separate supplies where the second takes over if the first fails—this involves a switchover event. The T8193’s TMR design provides continuous, voted power with no switchover delay or glitch. Compared to power supplies from other safety system vendors, the T8193’s deep integration with the Tricon diagnostics and hot-swap framework is a significant differentiator, providing a more seamless and manageable solution for high-availability applications.

Selection Guidelines and Important Considerations

Selection is paramount and must begin with verifying the exact chassis model number to ensure physical and electrical compatibility. The input voltage rating (AC or DC) must match the plant’s secure power source. When planning system configuration, the total power budget of all installed modules (CPU, I/O, comms) must not exceed the rated output capacity of the ICS TRIPLEX T8193. It is a best practice to ensure the module is powered from a dedicated, clean UPS source. For system expansions or replacements, it is critical to source genuine modules from authorized distributors. Refer to the official documentation for the ICS TRIPLEX T8193 for the latest compatibility lists and installation instructions to preserve system certification and warranty.
