Overview

The INFBU200-S1O is a compact, rack-mountable bus interface module designed for Yokogawa’s CENTUM VP distributed control system. It serves as a communication bridge between the system’s control processors and field I/O subsystems using the Vnet/IP protocol. This module supports full-duplex gigabit Ethernet, ensuring fast and stable data exchange across the control network.

Moreover, its star topology connection via switching hubs allows flexible system expansion and simplified network architecture. In addition, the INFBU200-S1O is built for industrial reliability, with robust performance under demanding environmental conditions. It is manufactured in Japan and backed by Yokogawa’s reputation for precision engineering and long-term support.

Therefore, this module is widely used in industries such as oil and gas, chemical processing, and power generation, where real-time control and high system availability are essential.

Technical Data

In addition, the module supports hot-swapping and diagnostic LEDs for easy maintenance and troubleshooting.
