Yokogawa SNT511-13 Optical ESB Bus Repeater Slave Module

The Yokogawa SNT511-13 is a key component in Yokogawa’s safety control systems. It serves as an optical repeater for the ESB Bus, extending the communication distance and ensuring reliable, high-speed data transmission between safety devices and controllers. This module plays a crucial role in enhancing the safety and functionality of process control and emergency shutdown systems.

Technical Specifications

• Transmission Distance:
  • Extends the ESB Bus by up to 2 km.
  • For multi-stage connections, the total distance can range from 5 km to 50 km.
• Data Rate:
  • Supports high-speed data transmission to ensure real-time communication.
• Current Consumption:
  • 0.5 A for optimal performance.
• Power Supply:
  • Requires an external power supply for operation.
• Weight:
  • Approximately 0.3 kg, making it lightweight and easy to install.
• Optical Attenuation:
  • Optical power is attenuated by 3-4 dB between SNT411, SNT511, and S2EN501 modules.
  • If fiber attenuation is less than 3 dB, an attenuator should be used to achieve proper signal levels.
• Environmental Conditions:
  • Designed to operate in a wide range of temperatures and humidity levels, suitable for harsh industrial environments.
