The F802 module is part of a modular system where two power modules typically reside on a dedicated carrier to provide 1+1 redundancy. It incorporates power conditioning, which is essential for fieldbus communication to prevent the DC power source from interfering with digital signals. Unlike the lower-power F801 variant, the F802 is designed for high-power requirements, making it suitable for long cable runs or heavily loaded segments.

Product Parameters

Number of Channels: 8 independent fieldbus segments per module.
Output Voltage: $28.0\text{V}$ to $30.0\text{V}$ DC.
Output Current: Up to $500\text{ mA}$ per segment.
Input Voltage: $19.2\text{V}$ to $30.0\text{V}$ DC.
Current Limit: Fixed at approximately $> 520\text{ mA}$ per segment to protect against short circuits.
Isolation: $250\text{V AC}$ (rms) between fieldbus and input power; $200\text{V DC}$ between segments.
Power Dissipation: Approximately $24\text{W}$ at full load (redundant operation).
Operating Temperature: $-40\text{°C}$ to $+50\text{°C}$ at full load; up to $+65\text{°C}$ with $60\%$ load.
Weight: Approximately $1.50\text{ kg}$ per module.
Ingress Protection: IP20 rated.

Product Advantages

High Power Capacity: Delivering $500\text{ mA}$ at $28\text{V}$ allows for much longer trunk lengths (over $600\text{m}$ ) and supports more field devices per segment compared to standard power supplies.
Enhanced Reliability: The 1+1 redundancy with load sharing ensures that if one module fails, the other takes over the full load without interrupting communication.
Galvanic Isolation: Isolation between segments prevents a single ground fault from affecting other segments, significantly increasing the robustness of the entire network.
Automatic Termination: The module automatically provides the required $100\text{ }\Omega$ fieldbus termination for each segment, reducing the need for external components and simplifying installation.
Hot Swappable: Modules can be removed or replaced while the system is powered and operational without disturbing the fieldbus segments.

Important Considerations

Heat Dissipation: Due to the high power output, ensure the cabinet has adequate ventilation, especially when multiple modules are installed or when operating near the upper temperature limit.
Hazardous Area Use: While the F802 is often used in systems reaching into hazardous areas, the module itself must be installed in a Safe Area or a Zone 2 location inside a suitable IP54-rated enclosure.
Inrush Current: The F802 has a higher inrush current than the F801 (up to 4 times the rated current for $10\text{ ms}$ ). The bulk power supply feeding the carrier must be sized to handle this peak.
Alarm Monitoring: The module features a normally closed (NC) relay for alarms. If the voltage drops below $24\text{V}$ on a segment, the relay opens. In non-redundant applications, the alarm circuit will remain open unless a blanking module is used.

Product Applications

The Eaton F802 is primarily used in large-scale industrial automation environments that rely on FOUNDATION fieldbus technology.

Process Industries: Widely applied in oil and gas, chemical processing, and pharmaceutical plants where long distances between the control room and field instruments are common.
Fieldbus Barrier Systems: Ideal for powering High Power Trunk (HPT) applications where fieldbus barriers are used to connect intrinsically safe (Ex i) devices.
Large-Scale DCS Integration: Specifically designed for seamless integration with major Distributed Control Systems (DCS) such as Yokogawa CENTUM 3000, Honeywell Experion, and Foxboro I/A Series through specialized carriers.
