T8300 | ICS Triplex | Rack Trusted Expander Chassis

Configured for high-density system expansion within the Trusted TMR network, the ICS Triplex T8300 (T8300 Rack Trusted Expander Chassis) provides direct physical and electrical execution. The chassis serves as the mechanical and interconnect framework for modular safety components, facilitating high-speed data synchronization and power distribution across expanded I/O architectures.

Hardware Specifications

SIS Triple Modular Redundancy (TMR) Architecture

The T8300 chassis supports the integration of triple modular redundancy (TMR) 2oo3 architecture by providing a deterministic, high-speed optical backplane with 100 Gbps throughput. This architecture enables fail-safe state execution, where redundant modules communicate across the backplane to perform real-time voting and synchronization. Galvanic isolation is maintained between the power input stages and the module bus to prevent electrical noise propagation, while the chassis design ensures physical separation of redundant processing paths to prevent common-mode failures in the safety-critical loop.

Frequently Asked Questions

Q: Can the liquid cooling system be serviced while the TMR modules are active?

A: The liquid cooling system is integrated to maintain thermal stability for high-density configurations. Maintenance of the cooling loops must be performed following site-specific safety protocols, ensuring that module operating temperatures remain within limits during the maintenance window.

Q: How is backplane communication redundancy maintained?

A: The 100 Gbps optical backplane supports redundant data paths to ensure that communication between I/O modules and the controller remains deterministic. Fault-tolerant protocols are utilized at the hardware layer to manage path switching without interrupting the control scan cycle.

Field Installation Guidelines

1. Ensure the mounting surface is level and capable of supporting the specified rack weight.
2. Connect the 400 VAC power inputs to the N+2 redundant supply units, verifying that phase alignment matches the chassis requirements.
3. Integrate the liquid cooling supply lines, ensuring all couplings are pressurized and checked for leaks before activating the rack power.
4. Ground the chassis to the system common earth using the designated grounding lug to maintain the 100 dB EMI attenuation rating.
5. Install TMR modules by sliding them into the chassis guides until the optical and power connectors on the backplane are fully engaged.
