ANB10D-420/CU2N/NDEL | Yokogawa Node Unit

Introduction

The Yokogawa ANB10D-420/CU2N/NDEL is a high-performance Node Unit engineered for dual-redundant ESB Bus architectures. Designed to enhance industrial automation reliability, this unit seamlessly integrates with Field Control Units (FCUs) and supports up to eight I/O modules. Its robust power distribution and fault-tolerant communication make it a critical component in redundant industrial control systems.

Key Features & Benefits

✅ Reliable Dual-Redundant ESB Bus Connection

Connects to FCUs using ESB Bus Coupler Modules (EC401 or EC402).
Supports dual-redundant setups (Slot 7 & Slot 8) or single configurations (Slot 7 only).
Compatible with multiple FCU models, including A2FV50, A2FV70, AFV30, and AFV40.

✅ Flexible Power Supply Options
The ANB10D is available with multiple power input options to match diverse industrial power environments:

Voltage	Frequency	Power Consumption
100-120 V AC	50/60 Hz	200 VA, 120 W
220-240 V AC	50/60 Hz	230 VA, 120 W
24 V DC	N/A	5.5 A

✅ Modular & Scalable Design

Supports up to 8 I/O modules, allowing for a customized system configuration.
Designed for 19-inch rack mounting, ensuring space-efficient deployment.
Weight: Approx. 10 kg (with all I/O modules installed).

✅ Advanced Configuration & Component Support

Module Type	Function
Power Supply Modules (PW481, PW482, PW484)	Provide redundant power for I/O modules and transmitters. Terminal connections secured with M4 screws.
ESB Bus Interface Slave Module (SB401)	Facilitates dual-redundant ESB Bus connectivity. Requires two modules for full redundancy.
I/O Modules (Max: 8)	Supports a variety of I/O configurations, including communication modules (ALR111, ALR121, ALE111, ALF111, ALP121, A2LP131) when paired with A2FV50 or A2FV70 FCUs.

✅ Enhanced Compatibility & Compliance

The /NDEL option ensures backward compatibility with CENTUM VP R5 and earlier versions when used in CENTUM VP R6.01 or later environments.
ISA Standard G3 compliance and temperature resistance (-20°C to 70°C) available when connecting to Optical ESB Bus Node Unit ANB11.
ATEX/IECEx certification is achievable with the /ATDOC option, ensuring suitability for hazardous industrial environments.
