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

Hardware Specifications

DCS Process Interface and Communication Characteristics

The ANB10D-410/CU2N/NDEL S1 manages physical communication between Yokogawa Field I/O modules and Field Control Units through the ESB bus network. Moreover, the dual-redundant ESB architecture maintains communication paths through two independent bus channels.

The unit supports FIO module installation through its eight-module chassis structure. In addition, the backplane distributes power and communication signals between installed I/O modules and the ESB interface section.

For Yokogawa process control applications, the ANB10D series supports instrument signal processing architectures including 4-20 mA HART loop protocol interfaces, FOUNDATION Fieldbus / Profibus PA connectivity through compatible I/O modules, channel-to-channel isolation configurations, and cold junction compensation (CJC) functions when applicable field modules provide these capabilities.

The /CU2N configuration provides two ESB connector units, allowing physical ESB cable connection arrangements according to system topology requirements. Therefore, the node unit can integrate into redundant FCU communication structures using compatible Yokogawa ESB interface components.

Frequently Asked Questions

Q: Can the ANB10D-410/CU2N/NDEL S1 operate with a single power module installed?

A: The ANB10D-410 configuration specifies a dual-redundant power supply arrangement. System operation should follow Yokogawa configuration requirements for redundant power installation.

Q: How many FIO modules can the ANB10D chassis accommodate?

A: The ANB10D chassis provides installation capacity for up to 8 FIO modules connected through the internal backplane.

Q: Does the ANB10D-410/CU2N/NDEL S1 include explosion protection functions?

A: No. The model configuration uses the basic type code and does not include explosion-proof protection features.

Field Installation Guidelines

Install the ANB10D unit on a suitable 19-inch rack structure using the specified mounting hardware. Verify mechanical clearance before installation to maintain natural air convection around the chassis.

Route ESB communication cables separately from high-voltage power wiring to reduce electrical interference. Furthermore, maintain proper cable shielding and connect shield layers according to Yokogawa grounding practices.

Confirm that the installed power supply modules match the specified 100 – 120 VAC input range before energizing the node unit. Check all ESB connector connections, FIO module seating positions, and grounding points during commissioning.

Avoid applying mechanical stress to connector assemblies during cable installation. Additionally, inspect the backplane contacts and module locking mechanisms before system startup.
