Yokogawa ANB10D-425/CU2 ESB Bus Node Unit

The Yokogawa ANB10D-425/CU2, also cataloged as the ANB10D-425/CU2 ESB Bus Node Unit, operates as a dedicated hardware component for remote I/O integration and node data communication within CENTUM VP control platforms.

Suffix Breakdown & Model Matrix

• ANB10D: Base model designation for the ESB Bus Node Unit.
• -4: Indicates the 24 V DC power supply variant.
• -25: Specifies the basic type configuration without explosion protection.
• /CU2: Designates the inclusion of 2 × ESB Connector Units (S9562FA).

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The ANB10D-425/CU2 processes distributed field signals and interfaces directly with CENTUM VP controller cards via high-speed ESB bus communication links. The 4-20 mA HART loop protocol compatibility ensures that analog process measurements and digital diagnostic packets transmit concurrently across the network layers without signal degradation. Channel-to-channel isolation parameters protect internal logic power planes from common-mode voltages and electrical transients originating in harsh field loops. Cold junction compensation (CJC) and precise thermal tracking maintain conversion linearity across all attached analog input and output modules.

Frequently Asked Questions

Q: Does this node unit support power supply redundancy configurations?

A: Yes, the architecture accommodates dual-redundant power supply modules and redundant ESB bus lines to ensure continuous node operation.

Q: What are the exact power supply input options for the ANB10D series?

A: While this specific -4 variant operates on 24 V DC drawing 5.5 A, other series suffixes support 100-120 V AC or 220-240 V AC input configurations.

Q: Can this unit be inserted or extracted while the rack is powered?

A: Power supply and communication modules support hot-swap procedures under specific system maintenance guidelines, but main node power isolation is recommended when servicing backplane elements.

Field Installation Guidelines

• Secure the 19-inch rack mountable chassis firmly into a standard industrial cabinet using appropriate structural fasteners and grounding points.
• Ensure that the 24 V DC power source is isolated and de-energized prior to connecting input terminal blocks or inserting power supply modules.
• Verify that the dual ESB bus cables are properly seated into the included S9562FA connector units to maintain deterministic data transmission integrity.
• Maintain a minimum vertical clearance of 50 mm above and below the chassis to allow unimpeded convective airflow through the thermal dissipation profiles.
