Hardware Specifications

Process Control and DCS Connectivity

• 4-20 mA HART Loop Protocol: The unit maintains signal transparency for I/O modules, facilitating the passage of primary process variables and HART diagnostic data between connected field devices and the Field Control Unit (FCU).
• FOUNDATION Fieldbus / Profibus PA Connectivity: The module supports the deterministic transport of Fieldbus and Profibus PA data packets through the backplane, ensuring stable communication timings across the CENTUM VP control hierarchy.
• Channel-to-Channel Isolation: High-density isolation circuitry within the backplane mitigates signal coupling and prevents electrical fault propagation between discrete and analog channels, protecting the node from field-side transients.
• Cold Junction Compensation (CJC): The unit is engineered to support thermocouple-based I/O modules by maintaining a stable internal thermal environment, ensuring the accuracy of CJC reference measurements during process monitoring.

Frequently Asked Questions (FAQ)

Q: Can this unit be used for redundant ESB bus communication?

A: No. The ANB10N series supports only single-bus communication. If your application requires redundant communication paths, the ANB10D series is required.

Q: Is the terminal node position mandatory for this hardware configuration?

A: Yes. Because the /CU2T connector includes integrated terminators, this unit is physically and electrically designed to serve as the final node in the ESB bus chain to prevent signal reflections.

Field Installation Guidelines

• Mechanical Mounting: Install the unit into a standard 19-inch rack. Ensure the chassis is securely fastened to the rack frame and bonded to the cabinet earth ground to maintain effective EMI/RFI shielding.
• Power Redundancy: Connect the dual power inputs to independent 100–120 VAC circuits. This ensures that a single supply failure does not result in the loss of power to the node's I/O modules.
• Bus Termination: As the /CU2T includes integrated S9564FA terminators, verify that this unit is placed at the physical end of the ESB bus segment. Ensure no further bus expansion is attempted from this connector.
• Licensing: The unit includes a pre-installed /NDEL license. Ensure the CENTUM VP software version is compatible with this node expansion key during system commissioning.
• Validation: Check the status indicators on the front panel post-installation to confirm active power on both redundant channels and synchronization of the ESB bus with the Field Control Unit (FCU).
