ICS TRIPLEX T9310-02 (Trusted TMR Backplane Expansion Cable / Interface Module)

T9310-02 is a backplane expansion component of ICS Triplex (now part of Rockwell) Trusted TMR safety system **, used for extending the backplane bus between racks to achieve I/O rack cascading and expansion, SIL3 certification, and triple redundancy architecture. 

I. Basic Positioning

Model: T9310-02 (Expansion Cable + Interface Module Assembly)

System: Trusted TMR SIS/ESD (Not AADvance)

Function: Backplane Expansion, extending the rack backplane bus, connecting remote I/O racks

Certification: SIL3, TÜV, CE, UL

Core: TMR Triple Redundant Bus Transmission, fault-tolerant

Core Parameters (Authoritative Compilation)

Type: Backplane Expansion Cable + Interface Module (2 meters)

Bus: Trusted Triple Redundant Backplane Bus (IMB)

Connector: D-sub High-Reliability Industrial Connector, both ends male / female compatible

Length: 2 m (standard)

Power Supply: 24VDC (system backplane power supply)

Operating Temperature: -40℃ ~ +70℃

Storage Temperature: -40℃ ~ +85℃

Humidity: 5%–95% RH (non-condensing)

Size (Module): Approximately 300×30×241 mm

Weight: Approximately 1.13 kg

Key Features

TMR Triple Redundant Transmission: Three independent signal channels, single-point failure without disturbance switching, SIL3 safety level.

Long-distance Rack Cabling: 2-meter cable extended backplane bus, enabling connection between the main control rack and remote I/O racks, reducing the complexity of on-site wiring.

High Anti-interference Design: Shielded Cable + Industrial-grade Connectors, anti-EMI/RFI, suitable for petrochemical, power station strong interference environments.

Hot Swap Compatibility: Compatible with Trusted Rack, supports online replacement of expansion modules / cables without interrupting system operation.

Diagnosis and Status Monitoring: Link failures, connection status can be diagnosed by the system, LED indicator lights provide intuitive display.

IV. Typical Applications

SIS/ESD Safety Instrumentation System: Key safety control scenarios in petrochemical, natural gas, power generation, pharmaceuticals, etc.

Remote I/O Rack Deployment: Backplane bus connection between the main control room and remote cabinets (such as explosion-proof I/O cabinets).

System Expansion: When the I/O slots of a single rack are insufficient, cascade expand the rack to increase the I/O points.

V. Model Clarification (Confusing Ones)

T9310-02: Trusted TMR Backplane Expansion Cable + Interface Module (2 meters), used for rack-to-rack bus extension.

T8314: Fiber Optic Transceiver Module, used for fiber optic extension of the bus (long distance, 10km).

98021/98522: AADvance Series I/O Base, belonging to different product lines from Trusted TMR.

T9310 (without suffix): Basic Version Expansion Cable, -02 is an upgraded version (enhanced shielding + high-temperature compatibility).
