Product Overview
The EC402-50 is a dual-port ESB bus coupler module designed and manufactured by Yokogawa for CENTUM series DCS control systems. This core bus bridging component resolves common industrial automation issues including insufficient bus expansion ports, low data transmission efficiency, and unstable communication linkage between FCU controllers and field node units. Yokogawa engineered this module to enable high-speed, reliable data interaction across ESB bus architectures, supporting system signal synchronization and equipment interconnection for large-scale process control frameworks. It serves process plant maintenance teams, system integrators, and engineering departments responsible for DCS system expansion, transformation, and routine maintenance. As a standard Yokogawa bus accessory, it stabilizes overall system communication efficiency and extends on-site bus layout distance.
Core Functional Features
-
High-Speed Bus Transmission: Supporting up to 128 Mbps high-speed data transmission, this bus coupler effectively reduces system communication latency, ensuring real-time and synchronous data exchange between controllers and distributed I/O node units.
-
Flexible Layout Expansion: With a maximum transmission distance of 10 meters per port and a total span of 20 meters, the module solves distance limitations of traditional bus wiring and supports flexible on-site DCS cabinet layout and expansion.
-
Excellent System Compatibility: Fully adapted to Yokogawa AFV30 and AFV40 series control units, this coupler realizes seamless bus docking and supports dual-redundant network configuration to improve system communication reliability.
-
Standard Industrial Compliance: Meeting CE, CSA, EAC and RCM industrial EMC standards, the module features strong anti-interference performance and stable operating adaptability for long-term continuous operation in process industrial environments.
