Product Description

The ANB10D-425/CU2T/NDEL is a high-performance ESB Bus Node Unit designed for integrated control within the Yokogawa CENTUM VP architecture. This unit functions as a robust communication hub, enabling seamless expansion of I/O modules while maintaining high system availability.

With a dual-redundant power supply configuration, the ANB10D-425/CU2T/NDEL ensures fail-safe operation, preventing process interruptions in the event of a power module failure.

Equipped with the /CU2T connector unit, the node includes an integrated terminator specifically designed for end-of-line ESB bus segments. The /NDEL suffix typically denotes compliance or labeling standards required for international industrial deployments.

Engineered for durability, the unit complies with ISA Standard G3, making it suitable for corrosive environments and operating temperatures ranging from -20°C to 70°C.

Technical Specifications

Application Context

The ANB10D-425/CU2T/NDEL is deployed in distributed control systems requiring continuous, high-reliability operation. It is widely used in petrochemical refining, pharmaceutical manufacturing, and power generation or utility plants.

Its primary function is to bridge the central processing logic of the Field Control Unit (FCU) with field instrumentation distributed across the plant, ensuring stable and efficient data communication.

FAQ

How does the dual-redundant power system function?
The unit incorporates two independent power modules. If one module or power source fails, the secondary module immediately takes over the load without interrupting ESB bus communication or connected I/O operations.

Is the /CU2T connector mandatory?
The /CU2T is an optional configuration that provides integrated ESB bus connection and termination. It simplifies installation by eliminating the need for external termination components and enhances overall signal reliability.
