Triconex 9802 I/O Bus Expander

Triconex 9802 I/O Bus Expander

Product Overview

• The Triconex 9802 is an I/O Bus Expander designed for the Triconex Safety Instrumented System (SIS), part of Schneider Electric’s EcoStruxure Tricon platform. It enables the connection of additional I/O modules to a Tricon chassis by extending the I/O bus, supporting the system’s Triple Modular Redundant (TMR) architecture. The 9802 is used in safety-critical applications in industries such as oil and gas, chemical, and power generation, ensuring reliable data transfer between the main chassis and expansion chassis while maintaining Safety Integrity Level 3 (SIL3) compliance.

Technical Specifications

• The 9802 has the following specifications based on standard characteristics for this model:

Additional Details

• The 9802 includes the following additional information based on its standard use and documentation:
• Function: Facilitates communication between the main chassis and expansion chassis, allowing the Tricon system to scale by adding I/O modules for applications like emergency shutdown (ESD), fire and gas detection, and burner management systems (BMS). Maintains TMR architecture for fault-tolerant data transfer.
• Mounting: Installs in a dedicated slot within the Tricon main chassis (e.g., 8110 or 8400); connects to expansion chassis via proprietary I/O bus cables.
• Compatibility: Compatible with Tricon v9.6 and later systems; works with chassis like 8110 (high-density) and 8400 (low-density), and supports I/O modules such as 3503E, 3700A, and communication modules like 4119A.
• Configuration: Configured via TriStation 1131 software; no user programming required for the expander itself, as it operates transparently to extend the I/O bus.
• Certifications: Meets IEC 61508 SIL3, UL, CE, and Factory Mutual (FM) standards for Class I, Division 2 hazardous locations; complies with IEC 61131 environmental and EMC requirements.
