        Features:

        • The T8902 provides the interface between the main Trusted Controller and remote I/O chassis, offering data transfer rates up to 250 Mbps via the Expander Bus to ensure real-time synchronization
        • It is built with Hardware-Implemented Fault Tolerance (HIFT) and a TMR architecture
        • The T8902 supports Smart Slot technology, which allows modules to be replaced or upgraded without interrupting system operation
        The T8902 serves as the dedicated Expander Interface Module, located in the processor slot of the expansion chassis . Its primary role is to connect the main Controller Chassis to additional Expander Chassis, enabling significant system I/O expansion. To maintain the deterministic performance required for safety logic, this connection utilizes a high-speed Expander Bus achieving data rates of up to 250 Mbps.

        Reliability is the cornerstone of the T8902, achieved through Triple Modular Redundancy (TMR). Critical circuits are triplicated and process data simultaneously, voting on the output . The module incorporates Hardware-Implemented Fault Tolerance (HIFT), allowing it to handle single-point hardware failures autonomously.

        The T8902 is designed for easy maintenance in live industrial environments. It supports Smart Slot technology, which allows a technician to remove and replace the module while the Trusted system is still powered up and running . Because the system is TMR, the Expander Bus does not drop out during the swap; the new module synchronizes automatically upon insertion.

        The T8902 ICS TRIPLEX Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Emergency Shutdown (ESD) Systems: Controls heavy-duty shutdown valves (ESDVs) that isolate hydrocarbons, toxic gases, or high-pressure steam loops across gas plants and refineries.
        • Burner Management Systems (BMS): Governs the rapid fuel-gas isolation solenoid valves on large utility boilers, cracking furnaces, and incinerators to prevent catastrophic deflagrations.
        • Emergency Trip Systems (ETS): Acts as the final physical control link to close main stop valves on high-value turbomachinery (steam/gas turbines and multi-stage axial compressors).
        • Channel Density: Packs 40 independent 24 Vdc digital output channels into a single slot, greatly optimizing cabinet space and reducing system footprints.
        • Current Capacity: Supports up to 2 A continuous current per channel. The module is systematically organized into 5 independent power groups (8 channels per group), with each group carrying up to an 8 A continuous load.
        • 2oo3 Architecture: Incorporates fully triplicated internal drive circuitry. Safety commands from the main processors undergo hardware-level Two-Out-Of-Three (2oo3) voting directly on the module before reaching the field.

        Description
        The T8902 is a critical Expander Interface Module within the ICS Triplex Trusted TMR (Triple Modular Redundant) safety system . Its primary function is to facilitate communication between the main Controller Chassis and one or more Expander Chassis, allowing the system to scale I/O capacity while maintaining rigorous safety integrity. 

        A key feature of the T8902 is its support for high-speed data transfer, achieving communication rates of up to 250 Mbps via the Expander Bus . This fast connection is established using a dedicated expander interface hot link cable (such as TC-301) and an adapter unit (like T8312) . 

        Built with Hardware-Implemented Fault Tolerance (HIFT) and a TMR architecture, the T8902 ensures that a single component failure will not interrupt communication to the expansion chassis . 

        Designed for high availability, the T8902 supports Smart Slot technology, which allows the module to be replaced or upgraded without shutting down the system . It provides a serial data interface supporting multiple protocols like Modbus and Profibus .

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What is the primary function of the T8902?
        The T8902 acts as an Expander Interface Module . It connects an Expander Chassis to the main Controller Chassis, allowing the system to add more I/O modules while maintaining TMR fault tolerance and high-speed communication .
        How does the T8902 ensure system reliability?
        It utilizes a Triple Modular Redundant (TMR) architecture with Hardware-Implemented Fault Tolerance (HIFT) . This provides "3-2-0" redundancy, meaning it can suffer a single component failure and continue operating without interruption.
        How fast is the communication on the T8902?
        The Expander Bus provided by the T8902 supports a very high data transfer rate of up to 250 Mbps . This high speed is critical for synchronizing large amounts of I/O data between the main processor and remote expansion racks in real-time.
        Can I replace a T8902 without shutting down the system?
        Yes, the T8902 supports Smart Slot technology . This allows the module to be replaced or upgraded while the system is still powered and running ("hot swap"), provided a redundant module is managing the bus.
