The YOKOGAWA ANB10D-425CU2N is a dual-redundant ESB bus node unit, designed as part of Yokogawa’s distributed control systems (DCS) to interface between the Field Control Unit (FCU) and field instruments through the ESB bus. This node unit plays a critical role in managing analog and digital I/O signals in demanding industrial environments, such as power plants, chemical processing, and manufacturing facilities. It also supplies power to the connected I/O modules, making it an essential component of scalable and reliable automation system architectures.
This node supports dual redundant power supplies and communication links to ensure high availability and fault tolerance, critical in process control where uninterrupted operation is vital. The ANB10D-425CU2N can communicate with up to 128 I/O modules, providing flexibility and scalability for complex control projects. It is compatible with a wide range of Yokogawa’s I/O modules, offering users the flexibility to customize the system based on specific application needs.
