Hardware Specifications

SIS High Availability Characteristics

• SIL3 certification: The repeater assembly maintains signal loop integrity compliant with SIL3 requirements, ensuring deterministic data transfer for critical safety logic execution.
• Triple modular redundancy (TMR) 2oo3 architecture: The unit is designed to interface with 2oo3 voting structures, facilitating seamless data flow without introducing single points of failure.
• Galvanic isolation: Each communication port incorporates galvanic barriers to prevent ground loop interference and high-voltage surges from impacting the safety-rated backplane.
• Fail-safe state execution: In the event of repeater module internal fault detection, the assembly initiates a defined fail-safe state to prevent transmission of corrupted safety parameters to the controller.

Frequently Asked Questions

Q: Does the VS6002 support hot-swapping of repeater modules?

A: Yes. The two-wide carrier design permits the removal and replacement of an individual repeater module while the system remains energized, provided the partner module maintains active network communication.

Q: Is the VS6002 carrier assembly compatible with standard DIN-rail mounting?

A: Yes. The assembly is designed for standard mounting within safety system cabinets; ensure sufficient clearance for airflow to prevent thermal degradation of the repeater electronics.

Field Installation Guidelines

• Mounting: Secure the two-wide carrier assembly to the cabinet mounting surface using the provided hardware. Ensure the carrier is level to facilitate proper seating of the repeater modules.
• Grounding: Bond the carrier chassis to the system instrument earth bus. Robust grounding is mandatory to ensure effective suppression of high-frequency noise and electromagnetic interference.
• Wiring: Connect SISNet cabling to the repeater modules according to the specific network diagram. Segregate signal cabling from high-power AC lines by a minimum of 150 mm to maintain the signal-to-noise ratio required for safety data integrity.
