Honeywell 51191578-100

Description

Product Description
The Honeywell 51191578-100 is a critical power supply module designed for the Honeywell Fault Tolerant Ethernet (FTE) network infrastructure, which serves as the high-availability data backbone for the Experion® PKS distributed control system (DCS). This module provides reliable, redundant DC power to FTE switches and other network components, ensuring uninterrupted communication between controllers, workstations, and I/O subsystems. The robust design of the Honeywell 51191578-100 is essential for maintaining network integrity, which is foundational to continuous process control and operator visibility. System architects rely on this power module to eliminate a single point of failure in the control network’s power path. Implementing a correctly specified 51191578-100 is a best practice for building resilient process automation architecture. The reliability of the entire control loop can depend on the consistent performance of this foundational component.

Product Parameters

• Module Type: Redundant DC Power Supply for FTE Network Equipment.

• Input Voltage: Typically accepts a wide-range AC input (e.g., 100-240V AC, 50/60 Hz).

• Output Voltage: Provides a regulated DC output (e.g., 24V DC or 48V DC) as required by the connected FTE switches.

• Output Current/Power: Specific amperage/wattage rating to support one or multiple connected switches (details must be confirmed from the official spec sheet).

• Redundancy: Designed for N+1 or 1:1 redundant configuration with another identical power supply module.

• Mounting: Typically designed for chassis mounting within a network rack or cabinet.

• Hot-Swappable: Allows for replacement without powering down the connected network equipment.

• Diagnostics: Features status indicators (LEDs) for power OK, fault, and load sharing.

Advantages and Features

• High Availability: Enables redundant power supply configurations, ensuring network devices remain operational even if one power supply fails.

• FTE Network Optimized: Specifically designed and tested for compatibility and reliability within the Honeywell FTE ecosystem, guaranteeing performance.

• Robust & Reliable: Built with industrial-grade components for continuous operation in control room or industrial enclosure environments.

• Hot-Swap Capability: Facilitates easy maintenance and replacement without causing network disruption, supporting high system uptime.

• Simplified Integration: Seamlessly integrates into the Experion PKS physical architecture, with clear wiring and mounting guidelines.

• Diagnostic Feedback: Provides immediate local visual indication of power health, aiding in rapid troubleshooting.

Application Cases in Various Fields

• Oil & Gas Refineries: Powers the core FTE switch fabric in a central control room that connects multiple domain controllers and operator stations monitoring a full crude-to-product process.

• Liquefied Natural Gas (LNG) Plants: Provides redundant power to network switches linking safety system controllers (FSC/SM) with the Experion PKS servers for integrated control and safety.

• Chemical Complexes: Ensures continuous power to the data highway connecting distributed control and I/O nodes across a large, multi-plant site.

• Power Generation: Used in combined-cycle power plant control networks to maintain communication between turbine controls, balance-of-plant systems, and the main DCS.

• Pulp & Paper Mills: Supports the high-availability network connecting section controls (e.g., stock prep, paper machine, coating) to a unified operator interface.

Comparison with Competing Products

• Vs. Generic Industrial Power Supplies: While standard 24V DC supplies are available, the <a href=”https://www.honeywellprocess.com/library/marketing/spec-sheets/51191578-100.pdf” target=”_blank”>Honeywell 51191578-100</a> is engineered for specific load characteristics, form factor, and direct compatibility with Honeywell FTE switches. It is part of a validated system solution.

• Vs. ABB (System 800xA Network Power): ABB’s network infrastructure for its 800xA system may use power supplies from partners like Cisco or Phoenix Contact, integrated per ABB’s design specs. Honeywell’s approach with the 51191578-100 offers a pre-validated, vendor-assured power solution for its specific FTE hardware.

• Vs. Emerson (DeltaV Switches with Integral Power): Some Emerson DeltaV network switches have integrated, internal redundant power supplies. Honeywell’s solution using external modules like the 51191578-100 can offer easier field replacement and may provide power to multiple devices from a single, centralized redundant source.

Selection Suggestions and Precautions

1. Verify Switch Compatibility: Confirm that the Honeywell 51191578-100 is explicitly listed as compatible with the specific model and generation of your Honeywell FTE switches (e.g., RPS12, RPS16).

2. Calculate Total Load: Sum the power requirements of all network devices that will be powered by this supply or pair of supplies. Ensure the 51191578-100‘s output capacity exceeds this total with a safe margin (typically 20-30%).

3. Plan for Redundancy: For critical network nodes, always deploy power supplies in a redundant (N+1) configuration. This requires purchasing at least two modules and ensuring the chassis or rack supports the redundant setup.

4. Follow Installation Guidelines: Adhere strictly to Honeywell’s installation manual for proper grounding, spacing for ventilation, and torque specifications for terminals to prevent overheating or connection failures.

5. Source Authentic Parts: Purchase only from Honeywell or authorized distributors. Non-genuine power supplies can have inferior regulation, noise filtering, and surge protection, risking erratic network behavior or damage to sensitive switch electronics.

6. Integrate into System Power Plan: Consider the input AC power source for these supplies. For maximum resilience, feed redundant 51191578-100 modules from separate uninterruptible power supply (UPS) branches or electrical panels.
