Product Overview
The Triconex 7400028-100, designated as Model 8101, serves as a 15-slot expansion chassis specifically engineered for the Triconex Triple Modular Redundancy (TMR) safety instrumented systems. This robust hardware platform enables the expansion of I/O capacity in demanding industrial environments, including petrochemical processing, power generation, and critical infrastructure control. By providing a stable physical and electrical foundation, this chassis allows for the seamless integration of additional I/O modules into the existing safety architecture, ensuring high system availability and fault tolerance.
Features
- Designed for high-density I/O expansion in TMR safety systems.
- Supports 15 slots for flexible module configuration.
- Engineered with a passive backplane to enhance reliability and MTBF by removing active bus components.
- Facilitates hot-swapping, allowing for module replacement or system expansion during active process operation.
- Integrated dual-power rail distribution supports redundant power supply modules for increased uptime.
- Physical slot keying ensures correct module alignment and prevents insertion errors.
Applications
This expansion chassis is widely utilized in safety-critical applications where process continuity is paramount. It is commonly deployed in emergency shutdown (ESD) systems, burner management systems (BMS), and high-integrity pressure protection systems (HIPPS) where the Triconex TMR architecture is required to mitigate risks and protect plant assets.

Installation Guidelines
- Ensure the chassis is mounted in a clean, dry, and vibration-dampened environment consistent with industrial safety standards.
- Maintain adequate clearance around the chassis to allow for proper airflow and cooling, preventing thermal throttling or hardware degradation.
- Verify that all power sources are disconnected before installing or removing the chassis from the cabinet.
- Use appropriate grounding procedures to connect the chassis frame to the system common ground to mitigate EMI/RFI interference.
- Ensure all redundant power supply modules are correctly seated and keyed before applying power to the bus.
- Perform a system verification check after hot-swapping any module to confirm proper communication with the Main Processor (MP).
FAQ
Is this chassis compatible with all Tricon series modules?
The 7400028-100 is designed for the Tricon TMR system. Please consult your specific system documentation or the Triconex product catalog to ensure module compatibility based on your current firmware and processor generation.
Does the chassis include power supplies?
The 7400028-100 is the expansion chassis frame. Redundant power supply modules are typically ordered separately to meet specific power budget requirements for your I/O configuration.
