Triconex 4000056-002 I/O Communication Bus Cable

Description

The Triconex 4000056-002 is a high-speed I/O Communication Bus Cable used to interconnect redundant chassis within a Triconex Triple Modular Redundant (TMR) safety system. Unlike standard data cables, this is a specialized, shielded ribbon or multi-conductor assembly designed to maintain the "Triplicated" signal path between the Main Processors (MP) and the various I/O Expansion Chassis.

Specifications

• Part Number: 4000056-002
• Cable Type: I/O Bus Extension / Interconnect Cable.
• System Compatibility: Triconex Version 9 and Version 10 (v9/v10) Systems.
• Configuration: Supports Triplicated (TMR) bus architecture.
• Connectors: High-density, multi-pin connectors with mechanical thumb-screws for secure industrial seating.
• Shielding: Enhanced EMI/RFI shielding to prevent signal corruption in high-voltage environments.
• Length: Standardized for intra-cabinet or inter-cabinet rack spacing (typically 2 to 6 feet, depending on the specific assembly variant).

Features

• Path Isolation: The internal wiring is physically partitioned to ensure that a single point of failure (such as a crushed cable or a short circuit) does not compromise more than one of the three redundant paths.
• Redundant Clocking & Data: Carries the proprietary Triconex I/O bus signals, including timing, data, and address lines required for the Main Processors to "vote" on I/O status.
• Ruggedized Outer Jacket: Designed for long-term installation in industrial control rooms, featuring a flame-retardant and chemical-resistant outer sleeve.
• Plug-and-Play Integration: Keyed connectors ensure that the cable cannot be inserted upside down or into the wrong port, which is critical during "hot" system expansions or emergency maintenance.
• Low Latency: Optimized for the high-speed backplane speeds required for SIL3 (Safety Integrity Level 3) response times.
