ICS TRIPLEX TC-301-02-4M5 – Local Expansion Cable | Trusted Control System Platform
Engineering Background
ICS TRIPLEX (now part of Rockwell Automation’s safety-critical portfolio) developed the Trusted Control System (TCS) as a triple-modular redundant (TMR) safety platform for high-integrity process industries. The TC-301-02-4M5 is a factory-specified local expansion cable that physically and electrically interconnects Trusted chassis modules within the same cabinet enclosure, enabling deterministic I/O expansion without signal degradation or latency penalties.
Product Positioning
Designed exclusively for the ICS TRIPLEX Trusted platform, the TC-301-02-4M5 is a non-negotiable BOM component for any engineer expanding a Trusted chassis locally. Its 4-metre rated length accommodates standard 19″ rack and 24″ deep cabinet configurations. Procurement engineers specifying spare-parts kits or commissioning new expansion racks will find this cable essential for maintaining SIL-rated system integrity.

Proven Application Environments
- Oil & Gas: Wellhead control panels, ESD systems, HIPPS installations requiring SIL 3 rated cabling
- Petrochemical & Refining: Burner management systems (BMS) and process shutdown (PSD) racks
- Power Generation: Turbine protection and boiler safety interlock systems
- Offshore Platforms: Fire & gas detection systems with Trusted TMR controllers
- LNG & Pipeline: Compressor control and emergency shutdown (ESD) panels
- Nuclear & Utilities: Safety instrumented systems requiring certified interconnect components
Engineering Advantages
- Platform-native design: Engineered to ICS TRIPLEX Trusted backplane specifications — no signal adaptation or impedance mismatch risk
- SIL 3 system integrity: Maintains the safety integrity level of the Trusted TMR architecture when used as specified
- EMC-hardened construction: Foil + braid double shielding suppresses radiated and conducted interference in high-noise industrial environments
- Plug-and-play installation: Keyed connectors prevent mis-mating; no field termination or crimping required
- Reduced commissioning risk: Factory-tested cable assembly eliminates field wiring errors in safety-critical expansion racks
- Long service life: Industrial-grade jacket and connector materials rated for continuous duty in harsh environments
System Architecture & Signal Flow
Within the ICS TRIPLEX Trusted Control System, the TC-301-02-4M5 connects the primary chassis backplane expansion port to a secondary local expansion chassis. The cable carries multiplexed I/O bus signals, power supervision lines, and chassis health monitoring data across all three TMR voting channels simultaneously. Signal routing is deterministic and latency-bounded, preserving the sub-millisecond response characteristics required by SIL 3 safety functions. The 4.5 m length is optimised for same-cabinet or adjacent-cabinet installations within a single marshalling enclosure.

Technical FAQ
Q: Can the TC-301-02-4M5 be used for remote expansion (chassis in separate cabinets)?
A: No. The TC-301-02-4M5 is rated for local (same-cabinet) expansion only. For remote expansion, ICS TRIPLEX specifies a separate remote expansion cable assembly. Contact us to identify the correct part for your topology.
Q: Is this cable compatible with the Trusted TMR T8000 series controllers?
A: Compatibility depends on the specific chassis generation and backplane revision. Please provide your chassis part number and firmware version when enquiring so our engineers can confirm fit.
Q: What is the maximum number of expansion chassis supported per cable run?
A: Per ICS TRIPLEX Trusted system architecture, each local expansion cable connects one primary chassis to one expansion chassis. Daisy-chaining is not supported on this cable type.
Q: Do you provide a warranty?
A: Yes. Konmask provides a 90-day functional warranty on all tested components. Extended warranty and on-site support arrangements are available for volume orders.
Q: Can you supply the mating chassis or other Trusted platform components?
A: Yes. Konmask maintains inventory across the ICS TRIPLEX Trusted product line including I/O modules, power supplies, communication cards, and chassis assemblies. Submit your full BOM for a consolidated quote.
