Yokogawa RB301 RIO Bus Interface Master Card

The Yokogawa RB301 is a RIO Bus Interface Master Card designed for Yokogawa's CENTUM VP and CENTUM CS distributed control systems (DCS). It serves as the communication bridge between a host controller (such as a PC or Field Control Unit) and Remote I/O (RIO) devices, enabling high-speed data exchange across distributed process control architectures.
