Yokogawa SEC401-51 ESB Bus Coupler Module

Overview
The Yokogawa SEC401-51 ESB Bus Coupler Module is a dedicated master bus interface hardware designed for Yokogawa CENTUM DCS control systems. Which is used to connect safety control units (such as S2SC70, SSC60, SSC50) and safety node units (such as SNB10D, SNT4).
As the core data transmission hub of the ESB bus network, this Yokogawa ESB Bus Module establishes stable communication connection between DCS main controllers and field I/O modules. It processes real-time signal interaction, data scheduling and instruction transmission, supporting the overall data operation of industrial distributed control systems.
🚀Fuction & features
- ESB bus master interface function: SEC401-51 is the ESB bus master, the communication hub between the safety control unit and the safety node unit, and manages up to 9 safety node units (such as SNB10D/SNT4 series).
- Model and suffix code description:
- SEC401-5: Standard type (non-explosion-proof).
- SEC401-E: Explosion-proof type (please refer to technical documents for selection).
- Suffix options: For example, -1 supports ISA Standard G3.
- Connection and transmission: SEC401-51 can connect up to 9 units ; transmission speed 128 Mbps (for I/O module data transmission).
- High-Speed ESB Bus Data Transmission: The Yokogawa SEC401-51 supports 128Mbps high-speed ESB bus transmission, which meets the high-frequency data collection and real-time instruction output requirements of large-scale DCS system nodes.
- Bus Network Expansion & Signal Scheduling : Each bus segment driven by the SEC401-51 module can access up to 9 connected units, realizing reasonable expansion of DCS system bus nodes. The module undertakes unified scheduling of upstream and downstream data, classifies and transmits field acquisition signals and control commands, avoiding data confusion and transmission delay in multi-device parallel operation.
