Yokogawa ANB10D-410/CU2T CENTUM VP ESB Bus Node Unit

Product Overview

The Yokogawa ANB10D-410/CU2T serves as a high-availability interface for expanding I/O capacity within the CENTUM VP Distributed Control System (DCS). This ESB Bus Node Unit facilitates high-speed, dual-path communication between the Field Control Station (FCS) and remote FIO modules. By integrating redundant power modules and a specialized terminator interface, the unit ensures deterministic data flow across the system backplane. We supply this unit as 100% Brand New and Original, providing a factory-certified solution for mission-critical process automation.

Part Number Breakdown: ANB10D-410/CU2T

Yokogawa utilizes a specific alphanumeric coding system to define the electrical and functional configuration of the node:

Engineering Advantages

The ANB10D-410/CU2T addresses specific technical hurdles in DCS deployment and maintenance:

• Eliminate Signal Reflections: The integrated /CU2T option provides a built-in terminator within the connector unit. This hardware-level termination prevents signal "echoes" on the ESB bus, which typically cause data corruption in long daisy-chained rack configurations.

• Continuous Process Uptime: The dual-redundant power architecture (Suffix -4) allows the node to draw current from two independent AC sources. If one power module fails, the secondary module instantly carries the full load, permitting online replacement without interrupting the control logic or field I/O signals.

• Redundant Path Communication: By supporting the dual-redundant ESB bus, this node maintains 100% visibility of field data even if one communication cable sustains physical damage. This dual-path system ensures high-speed, 128 Mbps synchronization remains intact.

• Industrial Noise Immunity: Specifically engineered for the 100-120V AC standard, the internal power modules filter high-frequency transients and electromagnetic interference (EMI) common in environments with large motors and high-voltage switchgear.

FAQs

• Does this unit require an external terminator?

  No. The /CU2T option includes an integrated terminator. You should place this specific model at the end of an ESB bus chain to provide the necessary electrical termination for the entire segment.

• Can I replace an ANB10S with this ANB10D model?

  Yes. The ANB10D (Duplexed) offers superior reliability compared to the ANB10S (Single). However, you must ensure your Field Control Station (FCS) has the dual-redundant ESB bus ports and cables to utilize the secondary path.

• Is this unit compatible with 240V AC power?

  No. Suffix "1" designates a 100-120V AC input. Connecting this unit to 240V AC will result in immediate hardware failure. For 240V applications, please request the ANB10D-420 model.

• What mounting accessories come with the unit?

  Standard units typically include the necessary M5 mounting screws and insulation bushes. The insulation bushes are essential to prevent ground loops between the 10 kg chassis and the rack frame.
