Brand: ICS Triplex
SKU: ICS Triplex T8310C

Description

T8310C: Product Overview

The ICS Triplex T8310C is an Expander Processor Module designed for the Trusted® System, a high-availability platform for critical process control and safety instrumented systems (SIS). Its primary role is to extend the system’s I/O capacity by managing communication between a main system chassis and up to four remote expander chassis. This module enables the creation of distributed I/O networks while maintaining the integrity and deterministic performance of the central controller.

Functioning as a communication gateway, the T8310C handles the high-speed, synchronized transfer of I/O data and control logic between chassis. It ensures that all I/O points across the expanded system are scanned and updated within the controller’s deterministic scan cycle. The module is engineered with Triple Modular Redundant (TMR) architecture, meaning three independent internal channels process all data simultaneously. This design provides fault tolerance, as a failure in a single channel is masked by the two functioning channels, allowing the system to continue operating without interruption.

As a core component of the Trusted System platform, the T8310C inherits the platform’s benefits of high reliability and scalability. The Trusted System is designed for applications requiring maximum uptime, and the T8310C is critical for engineers who need to distribute I/O over longer distances or consolidate points from a wide area back to a single controller. This architecture is commonly deployed in large-scale installations such as offshore platforms, power generation plants, and pipeline operations where centralized control of distributed equipment is necessary.

Core Features & Customer Value

Deterministic, High-Speed Expansion

The T8310C provides a deterministic communication link between the main controller chassis and remote I/O expanders. For the control engineer, this means that I/O points located hundreds of meters from the central processing unit behave as if they are locally installed, with no degradation in scan time or control logic performance. This capability is essential for complex regulatory control loops and high-speed interlock systems where timing precision is critical. It allows for a more flexible physical layout of the control system, reducing wiring costs and simplifying cabinet design.

Inherent Fault Tolerance

Built with a TMR architecture, the module ensures continuous operation even in the event of an internal component failure. Each of the three internal channels operates independently. For the end-user, this translates directly to enhanced system availability and reduced risk of process shutdowns due to hardware faults. This built-in redundancy is a fundamental requirement for Safety Instrumented Functions (SIFs) and critical control applications in industries like oil and gas, where unplanned downtime carries significant economic and safety consequences.

Maintainability and System Diagnostics

The hot-swappable design allows for the module to be replaced while the system remains online, a critical feature for maximizing plant uptime. Maintenance personnel can remove and insert the module without needing to shut down the controlled process. Comprehensive status indicators on the front fascia provide immediate visual diagnostics, enabling technicians to quickly assess the module’s health and identify any faulty channels. This reduces mean time to repair (MTTR) and supports proactive maintenance strategies.

Typical Applications

The T8310C is deployed in large-scale industrial facilities where I/O points are geographically dispersed but must be managed by a centralized, high-integrity controller. In offshore oil and gas platforms, it is commonly used to connect the central control room’s main chassis with remote I/O cabinets located in utility modules, wellhead areas, or drilling modules. This setup significantly reduces the amount of field wiring that must be run through hazardous areas back to the central control house, lowering installation costs and improving system reliability.

In combined-cycle power plants, the module facilitates the integration of turbine auxiliary systems and balance-of-plant equipment with the main unit controller. For example, a single Trusted system using a T8310C can manage I/O for the gas turbine, heat recovery steam generator, and steam turbine from a central location, ensuring coordinated control and seamless safety interlocks across the entire plant.

For pipeline transport and distribution systems, the T8310C enables the design of a highly available control system that covers multiple valve stations, pump stations, or compressor stations from a primary control center. The use of a deterministic, fault-tolerant expander link ensures that emergency shutdown commands issued from the center are executed at the remote stations with the required reliability and speed, which is critical for pipeline safety and environmental protection.
