Overview
The Yokogawa YNT511D-P42/KT Optical Bus Repeater is designed for Enhanced System Bus (ESB) networks where long-distance, high-reliability communication is required. It converts electrical control signals into optical signals, providing exceptional resistance to electromagnetic interference (EMI) and enabling dual-redundant communication paths for uninterrupted data transfer between controllers and remote I/O nodes.
Engineered for mission-critical industrial environments, this module ensures stable communication over distances of up to 4 km via optical fiber—ideal for facilities such as refineries, chemical plants, and power stations where control systems are distributed across large physical areas.
Moreover, the YNT511D-P42/KT supports 10BASE-2 cable types and integrates seamlessly with Yokogawa’s CENTUM VP and CENTUM CS 3000 systems. Its rugged construction, proven optical performance, and redundancy capabilities make it a dependable component for expanding or upgrading ESB communication infrastructures.

Typical Applications
-
Distributed Control Systems (DCS): Extends ESB communication between controllers and remote I/O racks in wide-area networks.
-
Oil & Gas Facilities: Provides EMI-immune, long-distance data transmission between central and field control units.
-
Chemical Processing Plants: Ensures reliable signal routing across hazardous and high-noise environments.
-
Power Generation: Enables fast, interference-free communication in turbine and boiler control systems.
-
OEM Automation Panels: Used in custom control architectures requiring fiber-optic communication for enhanced isolation and reliability.
Example: In a refinery DCS setup, the YNT511D-P42/KT bridges optical links between the main control room and remote I/O enclosures spread over several kilometers. This guarantees consistent signal integrity, network redundancy, and system uptime, even under harsh environmental conditions.
