TRICONEX 8110 High Density Main Chassis | Tricon Triple Modular Redundant Safety Platform
Engineering Background
The TRICONEX 8110 is the foundational main chassis of the Tricon Safety System — Schneider Electric’s flagship Triple Modular Redundant (TMR) programmable safety controller. Designed to meet IEC 61508 SIL 3 and IEC 61511 requirements, the Tricon platform is the global benchmark for high-integrity process safety in oil & gas, petrochemical, nuclear, and power generation industries. The 8110 chassis provides the physical and electrical backbone for all Tricon I/O and communication modules, enabling fault-tolerant control with continuous self-diagnostics and zero-downtime operation.
Product Positioning
The 8110 High Density Main Chassis is engineered for applications where process uptime and personnel safety are non-negotiable. Its high-density slot configuration maximizes I/O capacity within a compact footprint, making it the preferred choice for brownfield expansions and greenfield SIS (Safety Instrumented System) projects alike. Procurement engineers specify the 8110 when system architecture demands maximum channel density, deterministic response, and proven field reliability across decades of continuous operation.

- Deterministic Scan Time: Guaranteed cycle time ensures predictable safety response within defined SIL 3 parameters
- Backward Compatibility: Integrates with existing Tricon installations, protecting prior capital investment
- Extensive Diagnostics: >99% diagnostic coverage — faults are detected, annunciated, and isolated before they can affect process safety
- Global Installed Base: Thousands of Tricon systems in continuous operation worldwide since the 1980s — unmatched field-proven reliability
System Architecture & Signal Flow
The 8110 chassis houses the Tricon Main Processor Modules (MPMs) across three redundant legs (Leg A, Leg B, Leg C). Each leg independently executes the safety application program and reads field I/O. The TMR voter compares outputs from all three legs and passes the 2oo3 majority vote to field actuators. The high-density backplane routes power, communications, and I/O signals between all installed modules with full electrical isolation between legs. The chassis also accommodates the Tricon Communication Module (TCM) for integration with DCS, SCADA, and historian systems via standard industrial protocols.
