Product Description

The ANB10D-425/CU2 is a high-availability interface node engineered for the Yokogawa CENTUM VP distributed control system (DCS). It functions as a critical expansion point, enabling the integration of multiple I/O modules while maintaining a high-speed, synchronous connection to the Field Control Unit (FCU).

With a dual-redundant power architecture, the ANB10D-425/CU2 ensures uninterrupted process data flow, even in the event of a power module failure. This makes it an essential component for mission-critical industrial operations.

Optimized for high-voltage environments, this model supports a 220–240 V AC input and is classified as a Basic Type unit, suitable for standard industrial applications without explosion-proof requirements. The unit provides eight slots for FIO (Field Internal I/O) modules, supporting scalable and flexible system expansion.

Technical Specifications

Application Context

The ANB10D-425/CU2 is widely used in industries requiring reliable and scalable distributed control systems, including:

• Power generation

• Water treatment

• Chemical processing

It extends the DCS network from the central control room to remote field cabinets, enabling localized signal processing and reducing the need for long-distance wiring.

FAQ

How does the dual-redundant power supply benefit the system?
The unit uses two independent power modules. If one module fails or loses input power, the secondary module instantly takes over, ensuring continuous operation and preventing process interruptions.

Does the /CU2 suffix include a terminator?
No, the /CU2 refers to the standard ESB bus connector unit without a built-in terminator. For end-of-line applications, the /CU2T variant (with integrated termination) should be selected.
