Product Description

The ANB10D is a high-availability expansion interface designed for the Yokogawa CENTUM VP distributed control system (DCS). It serves as the core hardware platform for mounting and interfacing multiple I/O modules with the Field Control Unit (FCU) via a high-speed synchronous ESB bus.

With a dual-redundant power supply architecture, the ANB10D ensures continuous operation even in the event of a single power source or module failure. This design makes it highly suitable for mission-critical automation environments where uptime is essential.

The unit supports up to 8 FIO (Field Internal I/O) modules, providing a scalable solution for expanding I/O density within a control system. Typically installed in a standard 19-inch rack, it also functions as a localized power distribution hub for all connected modules.

Technical Specifications

Application Context

The ANB10D is widely used in large-scale industries such as:

• Oil and gas refining

• Chemical processing

• Power generation

It enables expansion of DCS I/O capacity by allowing high-density module placement within localized control cabinets. Its redundant power design makes it ideal for safety-critical systems where unplanned downtime is unacceptable.

FAQ

What is the function of the connector unit on the ANB10D?
The ANB10D requires a connector unit such as /CU2N or /CU2T. The /CU2N is used for intermediate nodes in an ESB bus chain, while the /CU2T includes a built-in terminator and is used for the final node to ensure proper signal integrity.

Can this unit be hot-swapped during operation?
The ANB10D base unit itself should not be replaced while the system is active and must be properly isolated. However, individual I/O modules installed in the unit generally support hot-swapping to minimize process disruption.
