Product Description

The F802 is a plug-in power module used in conjunction with a module carrier (such as the F880 or F890 series). It provides DC power to eight fieldbus segments. When two F802 modules are installed on a single carrier, they operate in a redundant configuration with load sharing. If one module fails, the other seamlessly takes over the full load to prevent network downtime. It features built-in power conditioning, galvanic isolation, and segment termination.

Product Parameters

Product Advantages

• High Power Density: Provides 500mA per segment, making it ideal for heavily loaded segments or long trunk cables (>600m).

• N+1 Redundancy: Enhances system availability by allowing modules to share the load and provide backup in case of failure.

• Hot-Swappable: Modules can be replaced while the system is live without interrupting the power to the fieldbus segments.

• Integrated Diagnostics: Includes a built-in alarm relay and visual LED indicators to quickly identify short circuits or low-voltage conditions.

• Reduced Footprint: Compact modular design reduces cabinet space requirements compared to single-segment power supplies.

Key Considerations & Precautions

• Thermal Management: Ensure adequate ventilation. While the F802 can operate up to 65°C, it must be de-rated to 60% load at high temperatures.

• Module Matching: For redundant operations, it is recommended to use two identical modules (two F802s) rather than mixing with the lower-output F801.

• Ingress Protection: The module itself is IP20. It must be installed in an enclosure (e.g., IP54) if used in dusty or wet environments.

• ESD Protection: Always use anti-static precautions when handling the module to avoid damaging sensitive internal electronics.

Typical Applications

The F802 is widely used in process automation where Foundation™ Fieldbus H1 protocols are utilized:

• Oil & Gas: Powering field instruments in refineries and offshore platforms.

• Chemical Processing: Supporting large-scale instrumentation networks in corrosive or hazardous environments.

• DCS Integration: Commonly used as the power layer for Emerson DeltaV, Yokogawa Centum, and Honeywell Experion control systems.

• Power Generation: Managing sensor and actuator networks in turbine and boiler control systems.
