Yokogawa ANB10D-420/CU2T/NDEL Node Unit

Overview

The YOKOGAWA ANB10D-420/CU2T/NDEL is a Node Unit designed for dual-redundant ESB Bus configurations. It provides robust connectivity for Field Control Units (FCUs) and supports up to 8 I/O modules. This unit is engineered for high-reliability industrial automation systems, ensuring seamless communication and power distribution in redundant setups.

ESB Bus Node Connection

Connects to the FCU using ESB Bus Coupler Modules (EC401 or EC402).
Slot allocation for ESB Bus Coupler Modules:
- Slot 7 & Slot 8: Required for dual-redundant configurations.
- Slot 7 only: Required for single configuration (Slot 8 must be empty).
Compatible FCUs: A2FV50, A2FV70, AFV30, AFV40.

Power Supply Options

The ANB10D supports various power input options, which must be specified using suffix codes:

Voltage	Frequency
100-120 V AC	50/60 Hz
220-240 V AC	50/60 Hz
24 V DC	N/A

Power Consumption

Power Supply	Power Consumption
100-120 V AC	200 VA, 120 W
220-240 V AC	230 VA, 120 W
24 V DC	5.5 A

Physical Characteristics

Specification	Value
Weight	Approx. 10 kg (including 8 I/O Modules)
Mounting	19-inch rack mounting (M5 x 4 screws)

Configuration and Components

The ANB10D supports a modular design with the following components:

Module Type	Description
Power Supply Module (PW481, PW482, or PW484)	Powers I/O modules and transmitters; uses M4 screws for terminal connections. Supports dual-redundant configurations (two modules required).
ESB Bus Interface Slave Module (SB401)	Ensures dual-redundant ESB Bus connectivity (two modules required).
I/O Modules (Max: 8)	Supports various I/O configurations. When used with A2FV50 or A2FV70, only communication modules (ALR111, ALR121, ALE111, ALF111, ALP121, A2LP131) are supported.

ANB10D	Node Unit for Dual-Redundant ESB Bus

Suffix Codes

Code	Description
-4	Dual-redundant power supply
2	220-240 V AC power supply
0	Basic type (no explosion protection)

Optional Features

Option Code	Description
/CU2T	Connector Unit with Terminator for ESB Bus (Part No.: S9564FA – 2 pieces)
/NDEL	Ensures compatibility with CENTUM VP R5 or earlier when used with CENTUM VP R6.01 or later
/ATDOC	ATEX/IECEx compliance for potentially explosive atmospheres

Additional Notes

When connecting ANB10 to the Optical ESB Bus Node Unit (ANB11), additional options such as ISA Standard G3 compliance and temperature resistance (-20 to 70 ºC) are available.
ATEX/IECEx compliance is achieved by selecting the /ATDOC option.

Application

The YOKOGAWA ANB10D is ideal for large-scale industrial automation systems, particularly in:

Process control plants requiring high-reliability redundant configurations.
Power generation, oil & gas, and chemical industries where ESB Bus communication is essential.
Mission-critical automation networks demanding dual-redundancy and seamless integration with FCUs and I/O modules.
