Description

TC-301-02-2M5: Product Overview
The ICS Triplex TC-301-02-2M5 is a specialized interconnect cable designed for the Trusted TMR (Triple Modular Redundant) system platform, providing the critical communication link between a main controller chassis and an expander chassis. This cable assembly enables system expansion by extending the triple-redundant backplane architecture over a 2-meter distance, allowing for physical separation between the primary controller and additional I/O modules while maintaining the system’s fault-tolerant characteristics.
The cable implements a triple-redundant communication path that carries synchronized clock signals, data communications, and power between chassis. Each of the three redundant channels is physically separated within the cable assembly with individual shielding to prevent cross-talk and ensure signal integrity. The cable connectors are keyed to prevent incorrect installation and designed for high-cycle mating durability, supporting the maintenance requirements of industrial environments where modules may need periodic servicing or replacement.
As an integral component of the Trusted system’s expansion capability, this cable maintains the timing synchronization and data coherence required for proper TMR system operation. The length of 2 meters provides flexibility in cabinet layout while ensuring signal integrity is maintained within the system’s electrical specifications. The cable’s construction meets the same environmental and EMI/RFI immunity standards as the Trusted system components, ensuring reliable operation in harsh industrial environments.

Core Features & Customer Value
Maintained Signal Integrity: The cable’s design with individual channel shielding and proper impedance matching ensures that critical timing and data signals remain intact over the 2-meter distance between chassis. This prevents signal degradation that could lead to synchronization errors between the TMR channels, which is essential for maintaining the system’s fault-tolerant capabilities. The benefit for system integrators is the ability to physically separate system components for better heat management or maintenance access without compromising system reliability.
Robust Industrial Construction: The cable assembly is designed to withstand the mechanical stresses and environmental conditions found in industrial settings. The connectors feature positive locking mechanisms to prevent accidental disconnection from vibration, and the cable jacket resists oils, chemicals, and abrasion. This durability ensures long-term reliability and reduces maintenance requirements, particularly important in systems where downtime can have significant operational consequences.
Plug-and-Play Expansion: The keyed connectors and standardized interface allow for straightforward system expansion without requiring complex configuration or calibration. This simplifies system design and reduces engineering time during initial installation or future expansions. The ability to easily add I/O capacity while maintaining the TMR architecture provides scalability for growing operational requirements.

Typical Applications
In power generation control systems, the cable connects the main turbine controller chassis to remote I/O chassis located near measurement points throughout the turbine enclosure. This allows the sensitive controller electronics to be located in a controlled environment while I/O modules are placed closer to field devices, reducing signal run lengths and improving measurement accuracy.
For chemical processing facilities, the cable enables distribution of I/O points across large processing areas while maintaining a centralized control architecture. The 2-meter length provides flexibility in cabinet arrangement, allowing for optimal space utilization in control rooms while maintaining the TMR system’s integrity.
In oil and gas safety instrumented systems, the cable supports redundant architecture configurations where physical separation between system components is required for safety or availability reasons. The maintained signal integrity ensures that safety functions operate correctly regardless of the physical distribution of system components.
