Fieldbus Solutions in Hazardous Areas: FieldConnex® Infrastructure

FieldConnex® Infrastructure: Reliable Solutions for Ex-Zones (PROFIBUS PA and FOUNDATION Fieldbus H1)

FieldConnex® by Pepperl+Fuchs is a comprehensive, reliable, and cost-effective infrastructure designed for integrating smart field devices into digital process networks. These solutions ensure uninterrupted power and communication in the most demanding environments, including hazardous areas (Zone 0, Zone 1, Zone 2), supporting the FOUNDATION Fieldbus H1 and PROFIBUS PA protocols.

Maximizing Efficiency: The High-Power Trunk (HPT) Concept

FieldConnex® systems are engineered to significantly reduce installation costs and increase plant availability through the innovative High-Power Trunk Concept.

• Economic Advantage (Up to 40%): HPT allows for significantly longer cable runs (up to 1900 m) and enables connection of a greater number of devices per segment, utilizing the cost-effective Ex e (Increased Safety) explosion protection method for the trunk line.

• Live Maintenance: By employing Intrinsically Safe (Ex i) protection on the spurs, you can connect and service field devices without powering down the segment, which critically reduces downtime.

• Simplified Architecture: Power and digital data are transmitted over a single two-wire line, which greatly minimizes the complexity and cost of cabling.

Key Components and System Protection

The FieldConnex® solutions comprise optimized modules that guarantee the integrity of your network:

1. Power Hubs (Fieldbus Power Supplies): These are compact and highly efficient modules that provide stable and redundant power (N+1) for fieldbus segments, crucial for continuous operation.

2. Segment Protectors / FieldBarriers: They connect intrinsically safe field devices (Ex i) to the trunk and provide short-circuit protection on individual spurs. A failure on one device will never affect the other devices on the segment.

3. Advanced Diagnostics Modules: These tools provide continuous online monitoring of the physical layer of the fieldbus. They automatically detect issues such as noise, degradation of surge protectors, or water ingress, and send warnings to the control system before a critical failure occurs.
