ICS TRIPLEX T8310C – Trusted TMR Expander Processor | Trusted Series Platform
Engineering Background: The ICS TRIPLEX Trusted Series is one of the most widely deployed Triple Modular Redundancy (TMR) safety platforms in high-consequence process industries. Designed to meet IEC 61508 SIL 3 requirements, the Trusted architecture underpins Emergency Shutdown Systems (ESD), Burner Management Systems (BMS), and High Integrity Pressure Protection Systems (HIPPS) across global petrochemical, power generation, and water treatment facilities. The T8310C functions as an expander processor within this architecture — extending the computational and I/O capacity of a Trusted TMR chassis without introducing single points of failure, maintaining the triple-redundant voting logic that defines the platform’s safety integrity.
Product Positioning: The T8310C is the expander variant of the Trusted processor family, distinguished from the primary processor (T8110) by its role as a subordinate processing node that expands system capacity in large-scale or geographically distributed control architectures. It is suited for applications where a single chassis cannot accommodate all required I/O points, or where physical separation of processing nodes is mandated by functional safety design. It is not a standalone controller — it operates in conjunction with a primary Trusted processor and is not interchangeable with non-TMR ICS TRIPLEX modules.

Proven Application Environments
- Petrochemical Refining: Crude distillation units | Fired heater BMS | Continuous high-temperature, high-pressure cycling with mandatory SIL 3 ESD response
- Offshore Oil & Gas: FPSO topsides control | Wellhead ESD and HIPPS | Saltwater atmosphere, vibration, and space-constrained rack environments
- Power Generation: Gas turbine control systems | Turbine overspeed protection | Millisecond-level response requirements with zero tolerance for spurious trips
- LNG Terminals: Liquefaction train control | Emergency depressurization systems | Cryogenic process monitoring with extended I/O point counts requiring expander processors
- Water & Wastewater Treatment: Large municipal SCADA systems | Chemical dosing and pump protection | Distributed architecture across multiple pump stations requiring expanded processing nodes
- Nuclear Balance-of-Plant: Non-safety-class auxiliary systems | Cooling water and HVAC control | Stringent EMC and environmental qualification requirements
Engineering Advantages
- For large-scale ESD systems exceeding single-chassis I/O capacity, this TMR expander processor extends the control architecture seamlessly, because it maintains the same 2-of-3 voting logic across all expanded nodes without architectural compromise.
- For applications requiring online maintenance, this processor module supports hot-swap replacement under live process conditions, because the TMR architecture continues voting on two remaining lanes during module extraction.
- For offshore and harsh-environment installations, this module delivers full SIL 3 integrity in compact single-slot form, because the Trusted platform consolidates redundant processing into a single chassis slot rather than requiring separate redundant controllers.
- For systems with long design lifespans (15–25 years), this ICS TRIPLEX processor benefits from an established global spare parts ecosystem, because the Trusted Series has been in continuous production and support since the 1990s.
- For multi-vendor DCS/SIS integration projects, this processor supports standard Modbus and OPC communication alongside proprietary Trusted protocols, because the dual Ethernet ports enable simultaneous historian and DCS connectivity.
- For engineering teams managing functional safety documentation, this module ships with traceable manufacturing records, because ICS TRIPLEX maintains full material traceability as part of its ISO 9001 and IEC 61508 quality obligations.
System Architecture & Signal Flow
Signal Flow: Field instruments → I/O modules (T8400/T8401 series) → Trusted TMR backplane → T8310C Expander Processor (three independent lanes: A, B, C) → 2-of-3 voting logic → Primary Processor (T8110/T8111) → Output modules → Final control elements (valves, trips, interlocks).
Compatible Modules:
- T8110 / T8111 — Primary Trusted TMR Processor; the T8310C operates as a subordinate expander node under these primary processors, sharing the same backplane and voting architecture.
- T8400 / T8401 — Trusted Digital Input modules; directly compatible via Trusted backplane, providing field signal acquisition to the T8310C.
- T8403 / T8404 — Trusted Analog Input modules; compatible for process variable monitoring within the expanded processor domain.
- T8431 / T8432 — Trusted Digital Output modules; receive voted output commands from the T8310C for final element actuation.
- T8090 Chassis — Standard Trusted TMR rack; the T8310C occupies one processor slot within this chassis.
Substitution Conditions: The T8310C is not directly interchangeable with the T8110 primary processor — substitution requires system architecture review and safety validation. Replacement with a T8311C (if applicable revision) requires firmware compatibility verification. Non-TMR ICS TRIPLEX modules (e.g., T8100 series) are not compatible.

Technical FAQ
Q: Is the T8310C compatible with all revisions of the Trusted TMR chassis (T8090)?
A: The T8310C is designed for use with the standard Trusted TMR T8090 chassis family. Compatibility with specific chassis revisions depends on firmware version alignment between the expander processor and the primary processor. It is strongly recommended to confirm revision levels of both the chassis and the primary processor (T8110/T8111) before ordering. Revision details can be provided upon request.
Q: Can the T8310C replace a T8110 primary processor if the primary processor fails?
A: No — the T8310C is an expander processor and cannot function as a primary processor. It does not contain the primary communication interfaces or the system master logic required for standalone Trusted system operation. A failed T8110 must be replaced with a T8110 or T8111 of compatible revision. Konmask.com stocks both T8110 and T8111 variants — contact support for availability.
Q: Does the T8310C carry IEC 61508 SIL 3 certification as a standalone module?
A: SIL 3 certification for the Trusted platform is a system-level certification — it applies to the complete Trusted TMR system (processor + I/O + chassis + power supply) as validated by ICS TRIPLEX and certified by TÜV or equivalent body. The T8310C, as a component of that certified system, contributes to the overall SIL 3 claim. Standalone module-level SIL certification is not applicable for TMR architectures of this type. For safety case documentation, the system-level certificate and FMEDA data are the relevant references.
