Yokogawa ANB10D-125/CU2T CENTUM VP ESB Bus Node Unit

Configured for node data communication and I/O expansion in CENTUM VP control platforms, the Yokogawa ANB10D-125/CU2T (ANB10D-125/CU2T ESB Bus Node Unit) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

• ANB10D: Base model designation for the ESB Bus Node Unit.
• -1: Indicates the 100-120 V AC power supply input configuration.
• -25: Specifies the basic type structural variant without explosion protection.
• /CU2T: Designates the inclusion of the ESB connector unit with an integrated bus terminator for terminal node placement.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The ANB10D-125/CU2T processes synchronous ESB bus traffic to maintain deterministic data exchange between Field Control Units and attached I/O modules. The 4-20 mA HART loop protocol compatibility ensures that analog field measurements and digital diagnostic packets pass concurrently without signal distortion across system networks. Channel-to-channel isolation parameters and ISA Standard G3 corrosive resistance protect internal processing layers from common-mode electrical transients and harsh atmospheric agents. Cold junction compensation (CJC) and internal thermal regulation maintain signal conversion linearity across extreme operating temperatures ranging from -20 deg C to +70 deg C.

Frequently Asked Questions

Q: What specific bus routing function does the /CU2T suffix provide?

A: The /CU2T option incorporates an integrated ESB bus terminator, making it the designated node unit for the terminal end of a bus segment to prevent signal reflection.

Q: Does this node unit support dual-redundant power supplies?

A: Yes, the architecture supports dual-redundant power modules running on 100-120 V AC to ensure continuous operation during individual power source failures.

Q: Can this hardware unit be serviced while the control cabinet backplane is energized?

A: Power supply and communication modules support hot-swap maintenance procedures under strict protocols, but complete node power isolation is recommended when servicing primary backplane links.

Field Installation Guidelines

• Mount the 19-inch rack enclosure securely into the industrial cabinet using M5 screws and ensure low-resistance bonding to the cabinet earth ground.
• Verify that the 100-120 V AC power supply source is de-energized prior to connecting input terminal blocks or inserting power modules.
• Connect the ESB bus cables securely to the /CU2T interface, ensuring proper bus topology termination rules are observed at the end of the segment.
• Maintain a minimum vertical clearance of 50 mm above and below the chassis to allow unimpeded convective airflow through the thermal dissipation profiles.
