Eaton F802 Power Supply Module

Description

Eaton F802 Power Supply Module

Product Dimensions：

The Eaton MTL F802 is a high-density, redundant fieldbus power supply module designed for use with FOUNDATION™ fieldbus H1 segments. It is a critical component in industrial process control systems, providing conditioned and isolated power to field devices.

Below is the detailed product information for the Eaton MTL F802.

1. Product Overview

The F802 is part of the MTL F800 series. It is a plug-in power module that mounts onto a carrier (such as the F880 or F890 carriers). It provides power conditioning and galvanic isolation for up to eight fieldbus segments.

• Primary Function: Redundant fieldbus power supply.

• Target System: Often used with Yokogawa Centum 3000, Emerson DeltaV, and other DCS platforms.

• Key Feature: “Hot-swappable” design allowing replacement without interrupting the fieldbus segment.

2. Technical Specifications (Parameters)

The F802 is specifically the “high-power” version compared to its sibling, the F801.

3. Product Advantages

• High Availability: Supports 1+1 redundancy. If one module fails, the other takes over the full load without dropping the communication or power.

• High Power Output: Delivering 500mA at 28V, it is ideal for long cable runs (up to 1900m) or segments with many field devices.

• Galvanic Isolation: Provides isolation between the input power and segments, as well as between individual segments, preventing ground faults from affecting the whole system.

• Easy Maintenance: Modules are hot-swappable, and the carrier itself contains no active electronic components, maximizing the Mean Time Between Failures (MTBF).

• Integrated Diagnostics: Includes a built-in alarm relay (normally closed) that opens if a segment is shorted or the voltage drops below a threshold.

4. Product Applications

The Eaton F802 is widely used in heavy industries where process uptime is critical:

• Oil & Gas: Offshore platforms and refineries.

• Chemical Plants: For controlling hazardous process loops.

• Power Generation: Providing stable power to field instrumentation.

• Pharmaceuticals: Ensuring continuous monitoring of batch processes.

5. Important Considerations (Precautions)

• Enclosure Rating: The module should be installed in an enclosure providing at least IP54 protection to shield it from dust and moisture.

• Inrush Current: Be aware that the F802 has an inrush current of up to 4 times its maximum rated current (duration <10ms). Ensure the bulk power supply can handle this.

• Mounting: Designed for 35mm DIN-rail mounting (Top-hat). Ensure vertical or horizontal mounting follows the airflow requirements for cooling.

• Hazardous Areas: While rated for Zone 2 / Division 2, always verify the specific local certifications before installing in explosive atmospheres.

• Wiring: Use appropriate conductor sizes (0.14 to 2.5 $mm^2$) and ensure the shield jumpers are correctly configured (isolated or grounded).
