ABB 216VC62A HESG324442R112/F

Description

Product Overview

The ABB 216VC62A HESG324442R112/F is a high-performance, modular power supply unit designed for critical industrial and power generation applications, particularly within ABB’s Advant/AC 800M DCS and Symphony Harmony systems. This unit is more than a simple converter; it is a highly reliable, redundant, and hot-swappable power system that provides conditioned and stable 24V DC power to the controllers, I/O modules, and other electronics in a process automation rack. The ABB 216VC62A HESG324442R112/F ensures that the control system remains operational even during fluctuations or partial failures of the primary AC power source. Its robust design and built-in diagnostics make it a cornerstone for maintaining system availability in environments like power plants, oil refineries, and chemical facilities where uninterrupted control is paramount. The specific configuration denoted by the suffix ensures compatibility and performance within a defined system architecture.

Product Parameters and Specifications

• Manufacturer: ABB

• Product Family: Advant / Symphony / System 800xA Power Supply Systems.

• Module Type: Modular, Redundant Power Supply Unit (PSU).

• Input Voltage: Typically accepts a wide range of AC input voltages (e.g., 85-264V AC) or DC inputs, providing flexibility for global installation.

• Output Voltage: Provides a precisely regulated 24V DC output, which is the standard for industrial control electronics.

• Output Power/Capacity: Rated for a specific power output (e.g., 480W, 960W) to support the load of all modules in a rack or cabinet. The “216” prefix often relates to the power rating.

• Redundancy Support: Designed for N+1 or 1+1 redundant configurations. Multiple ABB 216VC62A units can be paralleled with a redundancy module to share the load, so if one unit fails, the other(s) seamlessly take over without interruption.

• Hot-Swappable: Can be inserted or removed from the powered rack without needing to shut down the entire control system, enabling maintenance without process downtime.

• Diagnostics and Monitoring: Features LED status indicators for input OK, output OK, and fault conditions. It often provides a relay contact or communication signal to report its health status to the control system.

• Cooling: Typically employs fan-cooling for efficient heat dissipation in enclosed panels.

• Mounting: Designed for mounting on a standard DIN rail or a specific chassis within an ABB system cabinet.

• Ordering Code: HESG324442R112/F defines the specific hardware revision, configuration, and possibly included accessories like connectors or mounting plates.

Advantages and Key Features

1. High Availability through Redundancy: The primary advantage of the ABB 216VC62A HESG324442R112/F is its design for fault-tolerant power systems. When used in a redundant setup, it virtually eliminates single points of failure in the power path, which is critical for safety and continuous process operations.

2. Exceptional Reliability and Quality: Built with high-grade components and designed for 24/7 operation in harsh industrial environments, this power supply offers a very high mean time between failures (MTBF), ensuring long-term system stability.

3. Hot-Swap Capability: This feature allows for proactive maintenance or rapid replacement of a failed unit without scheduling a plant shutdown. An operator can simply unlock and replace the 216VC62A module while the redundant partner supports the load.

4. Wide Input Voltage Range: Its ability to handle a broad input voltage range protects the control system from brownouts and surges, ensuring stable output even with poor-quality mains power.

5. Comprehensive Diagnostics: Real-time monitoring of its own status allows for predictive maintenance. The system can alert operators to a failing power supply before it actually trips, allowing for planned intervention.

Application Case Studies

• Power Plant Turbine Control Cabinet: In a combined cycle gas turbine (CCGT) plant, the Mark VIe or other control systems rely on ultra-stable 24V DC. A redundant pair of ABB 216VC62A HESG324442R112/F power supplies ensures that the turbine controller and its critical I/O never lose power, preventing a forced outage that could cost hundreds of thousands of dollars per hour.

• Offshore Oil & Gas Safety System: For an Emergency Shutdown (ESD) system platform, power supply reliability is non-negotiable. Redundant 216VC62A modules provide the guaranteed power to SIL-rated safety controllers, ensuring they remain functional to execute shutdowns even during a primary power module failure.

• Pharmaceutical Batch Reactor Control: In a GMP environment, losing control power during a sensitive fermentation or chemical synthesis batch can ruin the product. The hot-swappable redundancy of this power system allows for maintenance during planned downtime without risking production batches.

Comparison with Competing Products

Selection Suggestions and Important Notes

• Selection Suggestion:

  • Choose the ABB 216VC62A HESG324442R112/F primarily as a direct replacement spare part for existing ABB systems or when designing a new system within the ABB Advant/800xA framework.

  • It is the specified choice when the application mandate calls for a hot-swappable, redundant power solution to achieve the highest possible system availability (often for Safety Instrumented Systems or critical continuous processes).

  • Always size the power supply by calculating the total 24V DC load of all devices in the cabinet, including controllers, I/O modules, communication processors, and any field devices powered from the rack. Allow for a 20-30% future expansion margin.

• Important Notes:

  • Exact Part Number Match: The full part number, especially the suffix (HESG324442R112/F), is critical for compatibility with the existing backplane, connectors, and redundancy logic modules. Using an incorrect variant can lead to mechanical or electrical fit issues.

  • Redundancy Configuration: To implement true redundancy, you must follow ABB’s specific guidelines, which often require a redundancy interface module and proper cabling. Simply installing two units does not automatically create a redundant system.

  • Cooling and Derating: Ensure the cabinet provides adequate airflow as per the manual. Power supplies may need to be derated (operated at lower than maximum capacity) in high ambient temperatures.

  • Input Power Source: Even with redundancy, the input AC power to all 216VC62A units should be sourced from a reliable and clean distribution point, ideally with its own upstream protection and conditioning.

  • Firmware/Version: For units with digital management, ensure the firmware version is compatible with the rest of the system.
