Pepperl+Fuchs R8D0

Fieldbus I/O module for hazardous zones

The series R8D0 from Pepperl+Fuchs is a rugged multi‑I/O interface engineered for industrial process automation applications using FOUNDATION Fieldbus H1 communication. Designed for installation in hazardous environments, this module consolidates multiple binary inputs and outputs into a single fieldbus‑powered unit, dramatically simplifying field wiring and infrastructure.

This device is part of the FieldConnex® family and serves as a versatile interface between smart sensors/actuators and distributed control systems. It supports direct connection of discrete sensors, frequency/count inputs, and low‑power valve outputs, all while maintaining intrinsic safety and full diagnostic visibility for both device and line conditions.

Core Capabilities:

• Fieldbus Standard: FOUNDATION Fieldbus H1 with FISCO and Entity support
• I/O Configuration: Multiple binary inputs and outputs, plus a configurable frequency/counter input channel
• Diagnostics: Local LED indication for power, communication, diagnostics, and errors; fieldbus‑based monitoring for predictive maintenance
• Power and Safety: Fieldbus‑powered with safe galvanic isolation per EN 60079‑11; intrinsically safe for Zone 1/Zone 2 applications with ATEX and IECEx certification

Robust Industrial Design

Built to withstand demanding environments, the module features a compact DIN‑rail cabinet mount package, IP20 protection, and mechanical resilience against shock and vibration. High‑quality polycarbonate housing and corrosion‑resistant construction ensure long‑term reliability in oil & gas, chemical, pharmaceutical, power generation, and similar sectors.

Installation and Integration

The device is easy to integrate with DCS/PLC systems supporting FOUNDATION Fieldbus, reducing wiring complexity and installation time compared to traditional discrete I/O schemes. Multiple plug‑in and spring/screw terminal options facilitate flexible field wiring and serviceability.
