YNT511D

Advantages and Features

• Bus Extension: Expands S3 bus length up to 2 km (optical) and increases node capacity for large-scale systems.
• Redundant Design: Supports dual redundancy to ensure continuous operation in fault-critical applications.
• Modular Flexibility: Easy installation and scalability via plug-and-play modules for custom configurations.
• High Reliability: 500V isolation and noise immunity protect against electromagnetic interference (EMI).
• Compact Size: Space-saving design (120 mm width) suitable for confined control cabinets.

Application Areas and Cases

• Industries: Petrochemical, power generation, water treatment, manufacturing.
• Case Example: A petrochemical plant used the YNT511D to extend S3 bus coverage across two production units, connecting 50+ I/O modules. The repeater’s redundancy and 2 km reach eliminated signal degradation, reducing downtime by 20% and improving process synchronization.

Competitor Comparison

Compared to standard bus repeaters, the YNT511D offers superior redundancy (dual vs. single) and longer transmission distances (2 km vs. 1 km typical). Its native compatibility with Yokogawa’s DCS ecosystem (CENTUM CS) minimizes integration complexity, unlike generic solutions requiring custom adapters.

Selection Recommendations

• System Scale: Choose based on required bus length (optical/electrical) and node count.
• Redundancy Needs: Opt for dual configuration (YNT511D + redundant power) for critical processes.
• Environment: Ensure IP54 rating matches site conditions (dust/water exposure).
• Power Type: Confirm AC/DC power requirements based on existing infrastructure.

Precautions

• Installation: Use shielded cables for electrical buses; follow Yokogawa’s wiring guidelines for optical fibers.
• Redundancy Setup: Activate dual repeater mode for fault tolerance; verify power supply redundancy.
• Maintenance: Schedule annual inspections for cable integrity and firmware updates.
• Safety: Disconnect power before module replacement; comply with NEC/CE standards for industrial networking.
• Compatibility: Only use Yokogawa-approved S3 bus devices to avoid protocol conflicts.
