The TC-308-02 is a dedicated Output Smart Slot Jumper Cable for the ICS Triplex Trusted system, used to enable redundant hot-standby connections for output modules. It is used to establish a physical connection between adjacent output slots to support the Smart Slot feature, allowing the replacement of faulty modules without interrupting the field actuator output.
56-Way High-Density Connectivity
Seamless Smart Slot Logic
1500V DC Galvanic Isolation
This type of Trusted Communications Cable is designed to provide I/O connection between a faulty Trusted Digital Output module (40 Channel only) and the I/O module occupying the SmartSlot position in a Trusted Controller or Expander Chassis. The SmartSlot end of the cable (SKT1) is fitted with a 96-way type ‘C’ connector housed in a single-width hood. The hood is fitted with an earth braid. The faulty I/O module end is fitted with a 96-way type ‘R’ connector housed in a special-to-type plastic hood.

Oil & Gas Refining
It ensures that safety isolation valves (XV) controlling burners or high-pressure reactors remain in their safe state during module replacement, preventing explosions caused by inadvertent trips.
Nuclear Power Generation
It guarantees that start-control signals for critical cooling pumps are not interrupted during controller maintenance, maintaining the heat removal capability of the reactor core.
Gas Turbine Power Plants
The TC-308-02 allows hot-swapping of faulty analog output modules without affecting the stability of the turbine speed.
LNG Storage & Transportation
It ensures that hydraulic solenoid valves controlling the emergency release of loading arms during LNG transfer do not fail due to a control module fault.
Semiconductor Abatement Systems
It ensures that control of dosing pumps and exhaust fans in abatement systems is not interrupted during module maintenance, preventing untreated toxic gas leaks.
When using the TC-308-02 Output Smart Slot jumper cable, ensure it is installed between adjacent output slots logically paired as "Active" and "Standby," and strictly check the locking screws to prevent loose contacts caused by vibration. As it carries 56 critical output signals, you must strictly adhere to the minimum bend radius specifications and protect the Megamide reinforced sleeving from physical abrasion against cabinet edges. Before performing a hot-swap, verify the redundancy status is "Ready" in the software, strictly avoid plugging or unplugging without proper redundancy configuration to ensure the continuous integrity of the output loop at the SIL 3 level.
It should be installed between the Field Termination Assemblies (FTA) on the rear of the chassis, connecting the corresponding interfaces of the main and standby modules, ensuring the locking screws are firmly secured.
Which modules is the TC-308-02 compatible with?
It is specifically used with Output Modules of the Trusted system, such as the T8451 (Analog Output) or T8461 (Digital Output) modules.
What is the difference between TC-308-02 and TC-306-02?
TC-306-02 is for input modules, while TC-308-02 is specifically for output modules. Their internal wiring logic and current/voltage characteristics are optimized for input and output signals, respectively.
What physical constraints should be noted when using the TC-308-02?
The minimum bend radius must be observed to prevent internal cable cores from being damaged under long-term pressure or excessive bending, which could affect the integrity of the output loop.
How to determine if the TC-308-02 is functioning correctly?
During system maintenance, observe the "Ready" or "Smart Slot" indicators on the module panel; if the LEDs are not lit, it usually means the jumper cable is poorly connected or the redundancy logic is not synchronized.
