Description

Yokogawa ANB10D-410/CU2N/NDEL S1 ESB Bus Node Unit

The Yokogawa ANB10D-410/CU2N/NDEL S1, also cataloged as the ANB10D Node Unit, operates as a dedicated hardware component for analog and digital field I/O signal transmission within CENTUM VP and CENTUM CS 3000 distributed control systems. It provides direct physical execution for dual-redundant ESB bus communication and I/O interfacing.

Process Control &DCS Features

The ANB10D series supports 4-20 mA HART loop protocol and ensures channel-to-channel isolation across field I/O modules. It accommodates FOUNDATION Fieldbus and PROFIBUS PA connectivity via the connector unit and provides cold junction compensation (CJC) for accurate thermocouple readings. Node expansion licenses (/NDEL) enable interfacing with AFV10/AFV30/AFV40 and AFF50 controllers, ensuring deterministic signal routing and compliance with backplane bus communication requirements.

Frequently Asked Questions

Q: Does the ANB10D allow hot-swapping of FIO modules?
A: Yes, all 8 I/O slots support hot-swapping without disrupting ESB bus communication, provided proper sequence isolation is maintained.

Q: What is the maximum load on the ESB backplane bus?
A: Each ANB10D supports the total current of installed FIO modules within the 200 VA chassis power rating; overload protection is internally managed by dual-redundant power supplies.

Q: Can firmware updates be performed in the field?
A: Firmware is compatible with S1 style revisions; updates require connecting through the FCU using Yokogawa’s standard ESB bus coupler interface modules.

Field Installation Guidelines

1. Install the ANB10D in a standard 19-inch rack using M5 screws, ensuring adequate airflow around the chassis.
2. Connect the dual-redundant 100-120 V AC power supplies to separate circuits if possible to maintain redundancy.
3. Route ESB bus cables using shielded twisted pairs and terminate connectors according to the CU2N module specification.
4. Maintain separation of analog and digital field wiring to reduce crosstalk and maintain channel-to-channel isolation.
5. Confirm that ambient temperature does not exceed 60 degC and humidity remains within 5-95% non-condensing range.
6. Verify hot-swap procedure by ensuring that power supplies remain operational and the FCU recognizes newly inserted FIO modules.
