Yokogawa EB402-50 ER Bus Interface Master Module

Product Introduction

The Yokogawa EB402-50 ER Bus Interface Master Module is an advanced communication interface designed for high-reliability distributed control systems (DCS). Serving as a master module in the ER Bus network, it enables precise and high-speed communication between system controllers and field I/O devices.

This module is engineered to deliver robust performance in critical industrial operations, featuring redundancy, self-diagnostics, and real-time error detection. Its design ensures seamless integration with Yokogawa CENTUM VP and other process automation platforms, making it an ideal choice for sectors like oil & gas, petrochemicals, power generation, and large-scale process automation.

The EB402-50 is optimized to handle complex process data, maintain system reliability under heavy loads, and operate efficiently in harsh industrial environments. Its dual-redundancy capability ensures that data transfer remains uninterrupted, even if one communication path fails, thereby improving system availability and safety.
