Description

Yokogawa ANB10S ESB Bus Node Unit

Configured for I/O signal interfacing and ESB bus communication in CENTUM VP and CENTUM CS 3000 systems, the Yokogawa ANB10S-415 (ANB10S ESB Bus Node Unit) provides direct physical and electrical execution for field I/O data exchange through a single ESB bus architecture. The unit supports N-IO/FIO integration and serves as the interface layer between control stations and distributed I/O assemblies.

FOUNDATION Fieldbus and Channel Isolation Considerations

The ANB10S functions within Yokogawa DCS architectures that support integration of field instrumentation using conventional analog interfaces and digital field communication technologies. When installed with compatible I/O assemblies, communication paths may support FOUNDATION Fieldbus network segments and conventional 4-20 mA signal loops.

Electrical isolation characteristics are implemented within associated I/O hardware to reduce channel-to-channel interference and maintain signal integrity between field devices and control applications. Isolation performance depends on the installed I/O module type rather than the node unit itself.

Frequently Asked Questions

Q: Does the ANB10S provide ESB bus redundancy?
A: No. ANB10S is designed for single ESB bus operation. Redundant ESB bus configurations require the corresponding dual-bus node unit model.

Q: Can different power supply voltages be selected for the same base model?
A: Yes. Power supply voltage is determined by the model suffix code, allowing selection of 100 - 120 V AC, 220 - 240 V AC, or 24 V DC versions.

Q: Is ISA Standard G3 environmental protection available?
A: Yes. Specific suffix options provide ISA Standard G3 environmental protection, with certain variants also supporting operation from -20 to 70 degC.

Field Installation Guidelines

• Install the node unit in accordance with the applicable CENTUM system cabinet and rack installation procedures.
• Maintain separation between ESB communication cabling and power wiring to minimize conducted electrical noise.
• Connect cable shields according to plant grounding standards and Yokogawa installation requirements.
• Verify suffix code compatibility before energizing the unit, particularly for power supply voltage and explosion protection requirements.
• Use the specified ESB connector units and terminators where required by the network topology.
• Ensure adequate cabinet ventilation and environmental conditions consistent with the selected model variant.
