EMERSON A6110

Description

Product Overview

The EMERSON A6110 is a critical dual power supply module designed for Emerson’s DeltaV S-series distributed control system (DCS). This unit is a key component in the system’s power infrastructure, providing redundant, conditioned power to the DeltaV S-series electronic marshalling cabinet components, including CHARM I/O cards and associated electronics. The EMERSON A6110 ensures high availability and reliability by seamlessly switching between two independent AC input sources to maintain uninterrupted DC power output.

Key Product Parameters

• Product Type: Dual AC Input, Redundant Power Supply Module

• Compatible System: Emerson DeltaV S-series with Electronic Marshalling (CHARMs)

• Input Voltage: Accepts two independent AC inputs, typically 100-240VAC, 50/60Hz.

• Output Voltage: Provides a single, regulated +24VDC output for field device power and I/O electronics.

• Output Current: Rated for a specific amperage (e.g., 10A) to support the power demands of the installed CHARM modules and related devices in its marshalling segment.

• Redundancy: Features dual, independent internal power circuits. If one AC source or internal circuit fails, the other automatically carries the full load without interruption.

• Mounting: Designed for mounting on a DIN rail within a DeltaV S-series marshalling cabinet.

• Diagnostics: Includes LED status indicators for power on, fault, and active source.

Advantages and Core Features

The primary advantage of the EMERSON A6110 is its built-in source redundancy, which significantly enhances system availability by eliminating a single point of failure in the power path. Its hot-swappable design allows for maintenance or replacement without shutting down the connected I/O and field devices. The module is specifically engineered for the electrical load profile of CHARM I/O cards, providing stable and clean power essential for accurate signal conditioning. The compact and integrated design of the A6110 simplifies cabinet layout and reduces wiring complexity compared to using two separate power supplies with external switching logic.

Application Scenarios

This power supply is used in any DeltaV S-series system utilizing Electronic Marshalling (CHARMs) across all process industries:

• Pharmaceutical & Biotech: Powering CHARM I/O cards in batch processes where production interruption is extremely costly.

• Oil & Gas Production & Refining: Providing highly available power to I/O for safety-critical and continuous process loops on offshore platforms or in refineries.

• Chemical Processing: Ensuring uninterrupted power for reactors, distillation columns, and material handling systems.

• Food & Beverage: Supporting I/O for pasteurization, fermentation, and packaging lines where downtime leads to product loss.

• Power Generation: Powering I/O for boiler control, turbine auxiliaries, and emission monitoring systems.

Comparison with Competing Products

Competing products include redundant power supplies from other DCS vendors like Siemens (SITOP PSU8600 for PCS 7) or ABB (specific 800xA power units). The EMERSON A6110 is distinguished by its native, plug-and-play integration with the DeltaV S-series electronic marshalling architecture. Unlike generic redundant power supply systems that require external diodes or controllers, the A6110 has redundancy and switching logic fully integrated and validated by Emerson, ensuring guaranteed performance and simplifying system design and documentation.

Selection Guide and Important Notes

Selecting the EMERSON A6110 requires calculating the total +24VDC power consumption of all CHARM I/O cards, isolators, and any other devices assigned to its power segment within the marshalling cabinet.

Important Precautions:

• Power Budgeting: Meticulously calculate the total load. The combined current draw of all connected devices must not exceed the A6110‘s rated output current, even during peak conditions.

• Independent AC Sources: For true redundancy, the two AC input lines must be sourced from independent circuits (preferably different distribution panels or UPS systems).

• Heat Dissipation: Ensure adequate space and ventilation around the module within the cabinet to prevent overheating, which can reduce its lifespan and reliability.

• Segmentation: In large systems, multiple A6110 power supplies are used to create separate power segments, isolating faults and limiting the scope of any single power failure.

• Wiring Compliance: Follow all local electrical codes and use the specified wire gauge for both AC input and DC output connections.
