Description
R-SP-E12 | FieldConnex Segment Protector, 12 Spurs, Ex eb mb, DIN Rail
R-SP-E12 Fieldbus Segment Protector with 12 short-circuit protected spurs for FOUNDATION Fieldbus H1 & PROFIBUS PA. Ex eb mb IIC T4 Gb, DIN rail mount, integrated 100 Ω terminator.

Product Overview

The R-SP-E12​ is a FieldConnex® Segment Protector​ designed for cabinet installation in hazardous areas (Zone 1 / Div. 2). It provides 12 individually short-circuit-protected spur outputs (Ex e)​ for connecting field instruments on FOUNDATION Fieldbus H1 or PROFIBUS PA​ segments. Each spur has independent current limitation to prevent a fault on one device from bringing down the entire bus segment. The unit features an integrated selectable 100 Ω terminating resistor, trunk/spur surge protection, and diagnostic LEDs (Power, Bus Activity, Termination ON, Channel Error). It is housed in a resin-filled polycarbonate enclosure for DIN rail mounting and carries ATEX / IECEx Ex eb mb IIC T4 Gb​ certification.

Key Features

  • Individual Spur Short-Circuit Protection:​ A shorted field device on one spur does not disrupt communication on the remaining 11 spurs — maximizes segment availability.
  • Ex eb mb Certification:​ Suitable for installation in Zone 1/Div. 2 with field devices in Zone 1/Div. 1.
  • Built-In Terminator & Surge Protection:​ Reduces external wiring; trunk and spur overvoltage protection included.
  • Diagnostic LEDs:​ Immediate visual indication of power presence, bus activity, terminator engagement, and which specific spur has a fault.
  • Resin-Filled Enclosure:​ Enhances ingress and vibration resistance for cabinet-mounted process automation environments.

Typical Applications

  • Process Plant Fieldbus Segments:​ Distributing FOUNDATION Fieldbus H1 or PROFIBUS PA to 12 instruments in oil & gas, petrochemical, and pharmaceutical plants.
  • Hazardous Area Retrofits:​ Upgrading existing analog loops to digital fieldbus with short-circuit isolation per spur.
  • Panel Builders / System Integrators:​ DIN-rail mounted segment protection inside certified enclosures for Zone 1 installations.
