Overview

The Yokogawa YNT512D-P11/KT module integrates Ethernet communication and dual-redundant V Net bus signal regeneration within a single compact unit. It is purpose-built for large-scale distributed control systems (DCS) that demand both remote network connectivity and robust internal signal transmission.

As an Ethernet interface, the module enables remote programming, centralized monitoring, and data sharing through standard TCP/IP and UDP/IP protocols. Simultaneously, as a V Net bus repeater, it regenerates and retransmits Yokogawa’s proprietary control signals, ensuring consistent communication across extended distances and multiple control nodes without degradation.

Its DIN rail mounting, dual power compatibility (AC/DC), and wide operating temperature range offer installation flexibility across a variety of industrial environments. With proven reliability, it forms a critical component in Yokogawa’s CENTUM VP, CS 3000, and FA-M3 architectures—ideal for mission-critical process automation.

Technical Data

Typical Applications

• Distributed Control Systems (DCS): Extends both Ethernet and V Net communication across multiple control nodes for enhanced scalability.

• Oil & Gas Facilities: Provides secure remote access and reliable bus signal regeneration across long distances in hazardous areas.

• Chemical Processing Plants: Maintains uninterrupted data exchange between control rooms and remote I/O stations under noisy electrical conditions.

• Power Generation: Supports centralized monitoring and redundant communication for turbines, boilers, and balance-of-plant systems.

• OEM Automation Panels: Ideal for custom control solutions requiring dual-protocol communication in compact, industrial-grade designs.

Example: In a refinery network, the YNT512D-P11/KT bridges Ethernet-based operator workstations with field control nodes using redundant V Net pathways. This configuration ensures continuous operation and data integrity, even during communication interruptions or maintenance events—making it vital for high-availability process systems.
