Overview

The Pepperl+Fuchs REG R9.28‑1 PCB Board is part of the company’s advanced FieldConnex® technology, engineered for FOUNDATION Fieldbus H1 integration. It is designed to connect multiple temperature or analog sensors directly into fieldbus networks, simplifying wiring and reducing installation costs. Moreover, its intrinsically safe design makes it suitable for Zone 1/Division 1 hazardous areas, ensuring compliance with ATEX and IECEx standards.

The REG R9.28‑1 supports thermocouples, RTDs (2‑, 3‑, 4‑wire), voltage, and resistance inputs, offering flexibility for diverse process applications. In addition, features such as cold junction compensation, sensor condition monitoring, and line fault detection enhance reliability and diagnostics.

Technical Data

Typical Applications

• Hazardous area temperature measurement loops requiring intrinsic safety

• Process automation systems in chemical plants and refineries

• Oil and gas platforms where multiple sensors must be safely connected

• Pharmaceutical manufacturing needing precise and reliable temperature monitoring

• Distributed control systems (DCS) integrating FOUNDATION Fieldbus H1 networks

For instance, offshore operators deploy the REG R9.28‑1 to connect multiple thermocouples and RTDs in Zone 0, while chemical plants rely on its diagnostics to maintain continuous operation even if one sensor fails.
