Yokogawa A2EE2A-T Optical Repeater Module
Product Brief Description
Yokogawa A2EE2A-T is an optical repeater module for CENTUM VP / CENTUM CS3000 DCS control network. It converts electrical Vnet/IP signals into optical signals for long-distance fiber transmission. The suffix -T indicates the single-mode fiber transmission version. It is used to extend the communication distance between control stations, HIS operator stations and remote cabinets, isolate electrical interference on the control network.
Product Functions
- Electrical to optical signal conversion for Vnet/IP DCS control network
- Single-mode fiber interface, realize long-distance inter-station communication
- Electrical isolation through optical transmission, suppress ground loop interference and surge
- Support redundant network topology to improve the reliability of DCS control network
- Front LED indicators for power, link status and communication fault alarm
- Hot-swappable design, can be replaced without stopping the DCS system
Application Scenarios
- Petrochemical, refinery and natural gas plant CENTUM series DCS control network
- Thermal power station, combined cycle unit long-distance control room interconnection
- Chemical, pharmaceutical and water treatment distributed control system
- Cross-building, cross-area remote control cabinet Vnet/IP network extension
- DCS network renovation, redundant network construction and spare replacement projects
FAQ
Q: What does A2EE2A-T mean?
A: A2EE2A is the optical repeater main model; -T stands for single-mode fiber type, while the -M suffix usually represents multi-mode fiber version.
Q: What is the difference between A2EE2A and ANB11D?
A: A2EE2A is Vnet/IP optical repeater for control network; ANB11D is ESB bus optical node for FIO I/O bus.
Q: What fiber type does A2EE2A-T use?
A: It uses single-mode optical fiber, which supports longer transmission distance compared with multi-mode version.
Q: Is it used for ESB bus?
A: No, it is dedicated to Vnet/IP control network, not ESB I/O bus.
Q: Is this module available for spare replacement?
A: It is a mature DCS network spare part. New surplus and refurbished units are supplied for maintenance of existing CENTUM DCS systems.
