Key Features & Benefits
Signal Integrity Preservation: Advanced signal conditioning circuitry eliminates noise and distortion, ensuring error-free data transmission even in electrically noisy industrial settings with heavy motor loads and VFD interference.
Flexible Network Topology: Supports both linear and star network configurations, allowing system integrators to design optimal layouts that minimize cable runs while maximizing reliability and maintainability.
Hot-Swappable Design: Field-replaceable without system shutdown, reducing maintenance downtime and enabling proactive component replacement during scheduled maintenance windows.
Application Scenarios
Large-Scale Process Plants: Extends Vnet/IP networks across multiple process units in refineries, chemical plants, and power generation facilities where control rooms are located hundreds of meters from field instrumentation.
Multi-Building Facilities: Bridges communication between separate buildings in pharmaceutical manufacturing, food processing, and water treatment plants, eliminating the need for costly fiber optic infrastructure in many applications.
Retrofit & Expansion Projects: Enables integration of new process areas into existing CENTUM systems without complete network redesign, protecting capital investment while accommodating facility growth.
Integration & Compatibility
Seamlessly integrates with Yokogawa CENTUM VP, CENTUM V, and legacy CENTUM CS systems. Compatible with AFV field control units, ALR communication modules, and third-party Modbus devices. Works in conjunction with SNT401 Optical ESB Bus Repeater for hybrid copper-fiber networks and ANT502-53 Optical Repeater for long-distance segments.
Installation & Configuration
Simple snap-on DIN rail mounting with screw-terminal connections for quick field installation. Auto-sensing baud rate detection eliminates manual configuration in most applications. Supports daisy-chain topology with up to 32 repeaters per network segment. Diagnostic LEDs provide instant visual feedback for troubleshooting.
Quality & Reliability
Manufactured to Yokogawa's stringent quality standards with industrial-grade components rated for 24/7 continuous operation. MTBF exceeds 100,000 hours under normal operating conditions. Conformal coating protects against humidity, dust, and corrosive atmospheres common in process industries.
