Yokogawa A2EE3A-N Vnet/IP Optical Repeater Module
Product Brief Description
Yokogawa A2EE3A-N is a Vnet/IP optical repeater module for CENTUM VP DCS control network. It converts electrical Vnet/IP Ethernet signals into optical signals for long-distance fiber communication. The suffix -N represents multi-mode fiber version. It is used to extend communication between control stations, HIS operator stations and remote cabinets, eliminating ground loop interference and improving network anti-interference capability.
Product Functions
- Realize electro-optical conversion for Yokogawa Vnet/IP control network
- Multi-mode fiber interface for medium-distance interconnection of control nodes
- Optical isolation suppresses common-mode interference and surge impact
- Supports redundant network configuration to guarantee high availability of DCS control network
- Front panel LED indicators for power, link status and communication fault alarm
- Hot-swappable design, replacement without system shutdown
Application Scenarios
- Petrochemical, refinery and natural gas plant CENTUM VP DCS Vnet/IP network
- Thermal power and combined cycle unit distributed control room interconnection
- Chemical, pharmaceutical and water treatment process control system
- Medium-distance cabinet interconnection in the same plant area
- DCS network upgrade, redundant transformation and spare parts replacement projects
FAQ
Q: What does A2EE3A-N mean?
A: A2EE3A is the model of Vnet/IP optical repeater; -N stands for multi-mode fiber, while -T is single-mode fiber version.
Q: What is the difference between A2EE3A-N and A2EE2A-T?
A: A2EE3A-N is multi-mode Vnet/IP repeater for shorter transmission distance; A2EE2A-T is single-mode version for longer fiber distance.
Q: Is it used for ESB bus?
A: No, it is dedicated to Vnet/IP control network, not ESB I/O bus. ESB optical node is ANB11D series.
Q: Can it work with redundant Vnet/IP network?
A: Yes, it can be deployed in dual redundant network architecture to meet the high reliability requirements of process control.
Q: Is this module available for spare replacement?
A: It is a mature Vnet/IP network spare part. New surplus and refurbished units are supplied for maintenance of existing CENTUM VP systems.
