The TC-306-02 is a dedicated Input Smart Slot Jumper Cable in the ICS Triplex Trusted system, used to enable hot-standby redundant connections between modules.It is primarily used to establish logical connections between adjacent I/O module slots to support the Smart Slot feature, ensuring no signal loss during module replacement.
Zero-Downtime Hot Standby
Superior EMC & Signal Integrity
Simplified Maintenance Logic
The ICS Triplex Trusted system is a premier Triple Modular Redundant (TMR), fault-tolerant control platform designed to meet the rigorous requirements of the IEC 61508 SIL 3 international functional safety standard. Its core feature lies in the 2-out-of-3 (2oo3) voting logic, which performs real-time comparison and validation of all critical commands across three independent internal processing channels. This not only eliminates single points of failure but also enables online hot-swapping of faulty modules without interrupting the process flow. With its superior availability and nuisance trip inhibition, the Trusted system has become the preferred solution for Emergency Shutdown (ESD), Fire and Gas (F&G), and Turbomachinery Control (TMC) in critical safety applications across the oil and gas, nuclear, and chemical industries.

Petrochemical Refineries
Used for critical process monitoring. In high-pressure reaction units like hydrocracking, it ensures sensor signal continuity during I/O module replacement, preventing costly nuisance trips.
Nuclear Power Plants
Used in Reactor Protection Systems (RPS). This cable ensures the system maintains the highest SIL 3 Safety Integrity Level during annual maintenance or module upgrades.
Steel & Metallurgy
The cable allows replacing damaged modules without shutdown, keeping safety cooling logic active at all times.
Pharmaceutical Industryl
Used for critical parameter monitoring of bioreactors.The TC-306-02 ensures seamless switching if an I/O module fails, maintaining continuous logs for temperature, pH, and agitation.
Desalination Plants
The TC-306-02 ensures that while maintaining pressure sensor modules, the system still monitors for pipe bursts, maintaining water supply stability.
When using the TC-306-02 Smart Slot jumper cable, ensure it is installed between adjacent slots logically paired as "Active" and "Standby," and strictly follow the minimum bend radius specifications to prevent damage to the internal shielding and signal integrity. After installation, verify that the Smart Slot status is "Healthy" in the software to confirm the redundancy logic is active. Additionally, regularly check the mechanical locking screws of the connectors for any loosening caused by industrial vibration, and strictly avoid plugging or unplugging without proper redundancy configuration to ensure the system's online maintenance capability at the SIL 3 level.
Connect the cable to the designated positions behind the main module chassis to link it with the standby slot (Smart Slot), achieving physical paralleling and logical synchronization of input signals.
Which modules is the TC-306-02 compatible with?
It is typically used with Digital Input (DI) or Analog Input (AI) modules of the Trusted system, such as the T8403 or T8431.
What role does the TC-306-02 play in a SIL 3 system?
It provides path redundancy at the hardware level, ensuring high availability and functional safety for the Safety Instrumented System (SIS) during online module maintenance.
Why can't general wires replace the TC-306-02?
Because it features specific impedance matching and proprietary connector packaging to meet the communication integrity requirements of the Trusted bus protocol.
How to verify if the TC-306-02 is connected correctly?
Monitor the Smart Slot status indicator via controller software (like ISaGRAF); if the connection is abnormal, the system will typically report a "Smart Slot Communication Fault."
