The ICS Triplex T8312-4 is a Trusted TMR Expander Interface module used to extend the high-speed Triplicated Inter-Module Bus across multiple chassis. It ensures seamless, SIL 3 rated communication between the main controller and expansion I/O racks in a distributed architecture.
Specifications
Bus Architecture:Triple Modular Redundant (TMR) Inter-Module Bus.
Operating Voltage:24 Vdc nominal (range 20 to 32 Vdc).
Power Consumption:15 W typical; 22 W maximum.
Safety Rating:IEC 61508 SIL 3 compliant.
Interface Ports:Three high-speed Expander Bus ports (A, B, and C).
Cable Type:Triple-shielded dedicated Expander Bus cabling.
Distance Support:Up to 30 meters between chassis (system dependent).
Fault Tolerant Extension:Maintains full triple redundancy across chassis boundaries, preventing a single cable or port failure from dropping the I/O rack.
Hot Swap Capability:Allows for the replacement of the interface module without interrupting the control logic or the safety function.
High-Speed Data Transfer:Optimized for low-latency synchronization of input/output data between the processor and remote modules.
Active Status Indicators:Features front-panel LEDs for immediate visual diagnostic of bus health and power status.
Automatic Configuration:Automatically recognized by the Trusted System software, simplifying the expansion of existing hardware setups.
Robust Hardware Voting:Implements 2oo3 voting logic on all incoming and outgoing bus signals to ensure data integrity.
