Description

The Triconex 8110 High Density Main Chassis serves as the primary structural and electrical foundation for the Triconex Triple Modular Redundancy (TMR) safety system. Engineered for safety-critical control environments, this chassis provides the necessary backplane infrastructure to house main processors, communication modules, and power supply units. It is designed to eliminate single points of failure, supporting continuous system availability and high-integrity operations in demanding industrial sectors such as petrochemical refining, nuclear power, and offshore energy production.

Features

• Supports Triple Modular Redundancy (TMR) architecture for high-reliability safety applications.
• High-density backplane design optimized for signal integrity and high-speed data synchronization.
• Facilitates hot-swappable module replacement to minimize unscheduled plant downtime.
• Ruggedized construction with integrated grounding lugs for mechanical stability and EMI/RFI shielding.
• Compatible with standard 19-inch industrial rack mounting systems.
• Electrical isolation built into the backplane to prevent fault propagation between modules.

Applications

The 8110 chassis is utilized in SIL 3 rated safety instrumented systems (SIS). Typical applications include emergency shutdown systems (ESD), burner management systems (BMS), and critical process control loops where high availability and fault tolerance are mandatory.

Technical Specifications

Installation Guidelines

• Ensure the chassis is mounted in a clean, dry, and vibration-dampened environment within a standard 19-inch rack.
• Verify that all grounding lugs are securely connected to the plant earth system to ensure effective EMI/RFI shielding.
• Power down the system before inserting or removing any modules to prevent electrical arcing or damage to the backplane pins.
• Maintain adequate clearance around the chassis to allow for proper airflow and cooling, adhering to the 0 to 60 deg C operating temperature range.
• Use only compatible Triconex-approved terminal blocks and cabling for field wiring to maintain system integrity.
