Main functions and applications
Trusted system controller redundant networking
Used for dual redundant data link connections between processors and communication cards in the main control rack, achieving triple TMR data voting and seamless switching between primary and backup controllers.
Engineer station / upper computer interfacing with the SIS system
Connects EWS engineer workstation, HMI upper computer and T8151 communication module to implement program loading, parameter configuration, fault events, SOE sequence data upload.
Local I/O rack and internal communication wiring of the main control cabinet
Safe bus signal transmission between multiple racks within the same control cabinet to ensure stable and uninterrupted communication of the ESD emergency stop interlock circuit.

 Core product features
Original factory dedicated cables for the TMR system
The wiring sequence, shielding, and impedance have been matched by the original factory, and ordinary network cables cannot be used as substitutes to avoid communication packet loss, system voting failures, and SIS mis-allocation.
Redundant dual-link design
02 represents dual-channel parallel transmission, a single wire core failure does not affect the overall communication, meeting the fault-tolerant design specifications for safety systems.
High-strength industrial protection
Outer layer woven wear-resistant mesh tube, which can be repeatedly bent in the narrow space of the cabinet, and can operate stably for 7×24 hours.
Pre-formed finished cables
Both ends are pre-installed with original factory shielding connectors, no on-site crimping is required, plug-and-play, eliminating the potential隐患of poor contact caused by on-site wiring.

Typical application scenarios
SIS/ESD emergency stop safety control system for petroleum， chemical， and coal chemical industries
Trusted system for safety interlock protection in thermal power plants， gas-fired power plants， boiler and turbine of steam turbines
Triple redundant safety instrument system for pipeline compression stations， storage tank areas， and large compressors stations
Functional safety control system networking for pharmaceutical and metallurgical high-risk process equipment
