Yokogawa ANT502-53
Product Introduction: A high-performance optical ESB (Extended Serial Bus) repeater slave module designed for Yokogawa’s CENTUM series DCS systems. It extends the communication distance of the ESB bus using optical fiber, enabling reliable long-distance data transmission between DCS nodes.
Technical Specifications:
- Bus Type: Optical ESB bus repeater (slave module).
- Transmission Distance: Up to 5 km over multi-mode optical fiber.
- Interface: Dual optical fiber ports (TX/RX) for bus extension.
- Compatibility: Designed for use with AFV30□/AFV40□ field control units.
Detailed content
- Isolation: Full galvanic isolation between optical and electrical circuits.
- Power Supply: 5 V DC from the DCS backplane.
- Environmental Rating: Industrial-grade, operating temperature -20°C to +70°C.
Key Features:
- Extends ESB bus communication up to 5 km, enabling large-scale DCS network deployment.
- Optical fiber transmission provides complete electrical isolation and superior noise immunity.
- Slave module configuration for seamless integration into existing ESB bus networks.
- Hot-swappable design allows for replacement without system shutdown.
- Robust construction for reliable operation in harsh industrial environments.
- Diagnostic LEDs for quick monitoring of bus status and link integrity.
- Plug-and-play installation with automatic bus configuration detection.
Applications:
- Long-distance communication between CENTUM DCS control units and field nodes.
- Interconnection of distributed control systems in large-scale process plants.
- Isolation of DCS segments to prevent ground loops and electrical interference.
- Expansion of DCS networks in refineries, chemical plants, and power generation facilities.
- Reliable data transmission in electrically noisy industrial environments.
