The Yokogawa ANB10S serves as a vital communication bridge within the CENTUM VP distributed control system (DCS). This ESB (Extended Serial Bus) Node Unit facilitates high-speed, deterministic data exchange between the Field Control Station (FCS) and remote I/O modules. Featuring a single power supply architecture, the ANB10S offers a cost-effective solution for non-redundant subsystems where high-speed 128 Mbps throughput remains a requirement. We provide this unit as 100% Brand New and Original to ensure seamless integration and long-term stability in your automation architecture.
Yokogawa ANB10S configurations typically vary based on power supply requirements and environmental coating:
ANB10S-A: 100–120 V AC Power Supply
ANB10S-B: 220–240 V AC Power Supply
Suffix /CU1: Features conformal coating for protection against corrosive gases (G3 environment)
Suffix /DIN: Includes DIN rail mounting kit instead of standard 19-inch rack brackets

High-Speed Determinism: The 128 Mbps ESB bus protocol ensures millisecond-level control updates. This speed allows the FCS to process remote I/O data with the same priority and synchronization as local rack signals.
Hybrid Module Support: The backplane architecture accepts both standard FIO (Field-network I/O) and modern N-IO (Network I/O) modules. This flexibility allows engineers to mix legacy hardware with the latest I/O technology in a single chassis.
Simplified Rack Management: The ANB10S fits into standard 19-inch racks and centralizes power distribution for all 8 slots. This eliminates the need for individual power cabling for every I/O module, reducing cabinet clutter and potential failure points.
Wide Thermal Range: Operating reliably between –20°C and +70°C, this unit survives in harsh industrial enclosures where temperature fluctuations are common, such as remote instrument enclosures (RIE).
Can I upgrade an ANB10S to a redundant power supply later?
No. The ANB10S chassis physically lacks the secondary power module slot. If your application requires power redundancy for high-availability processes, you must select the ANB10D model.
What is the maximum distance for the ESB connection?
Standard copper ESB cables support distances up to 10 meters. For remote I/O expansion up to 5 kilometers, you must integrate an optical ESB repeater (ERB series) and fiber optic cabling.
Does the ANB10S support online maintenance?
The node unit supports hot-swapping for individual I/O modules installed in its slots (provided the specific I/O module supports it). However, because this is a single-power unit, replacing the power supply module itself will require a temporary node shutdown.
