Yokogawa FIO System Interface ANB10D-425/CU2N ESB Bus Node

Product Description

Overview of the ANB10D Node Unit

The Yokogawa ANB10D-425/CU2N is a specialized ESB Bus Node Unit engineered for the CENTUM VP and CS3000 distributed control systems. Functioning as the communication hub for the Field I/O (FIO) system, this unit manages the data transmission between the Field Control Unit (FCU) and the mounted I/O modules. The node unit ensures that process data is transmitted accurately and rapidly, maintaining the integrity of the control loop.

This specific configuration supports a dual-redundant power supply architecture, significantly enhancing system availability by preventing shutdown during power source failures. It is factory-equipped with the /CU2N connector unit, which facilitates the physical connection to the ESB bus cables.

Technical Characteristics and Architecture

The ANB10D-425/CU2N is built to withstand the rigorous demands of industrial automation. It incorporates a rack-mountable chassis that fits standard equipment cabinets. The unit handles power distribution to the installed I/O modules while simultaneously executing bus communication protocols.

By utilizing the "425" suffix configuration, this unit is specified for high-voltage AC environments (220–240 V) rather than standard 24 V DC systems, making it suitable for facilities where AC mains power is the primary standard for control cabinets. The lack of explosion protection (Suffix 5) designates this unit for use in general-purpose, non-hazardous environments.
