Product Description
The EB402-50 is a high-reliability ER (Extended Remote) Bus master interface module for Yokogawa Electric Corporation’s FIO (Field network I/O) system, used in CENTUM VP and CS 3000 distributed control systems. It enables a Field Control Station (FCS) to manage I/O modules located in remote node units, allowing distributed plant topologies where I/O hardware is placed closer to field instruments.
The "-50" suffix indicates the module is optimized for 50-meter transmission distance, utilizing differential signaling to maintain deterministic communication and robust noise immunity in industrial environments.

Industrial Application
The EB402-50 is ideal for large-scale industrial plants such as offshore platforms, tank farms, and chemical processing facilities. It allows engineers to distribute I/O node units (e.g., ANB10) across multiple rooms or sections while maintaining centralized control logic execution within the FCS.
Engineering FAQ
Can the EB402-50 be used for distances shorter than 50 meters?
Yes. It works for shorter runs, though ESB Bus (SB401 modules) is recommended for very short, in-cabinet connections as a more cost-effective solution.
Does the EB402-50 support redundancy?
Yes. Installing two modules in the FCU provides a redundant ER Bus path, ensuring continuous control in case of cable or module failure.
What cables are required for the EB402-50?
Specialized Yokogawa YCB141 or YCB147 ER Bus cables are required, designed with proper impedance and shielding to meet the 50-meter distance specification.
