Pepperl+Fuchs WE77/EX‑2 | Intrinsic-Safety Switch Amplifier | 2‑Channel Relay Output

Overview

The WE77/EX-2 is a dual-channel intrinsic-safety-certified switch amplifier (EEx ia IIC) from Pepperl+Fuchs. Designed for hazardous-area applications, it interfaces NAMUR sensors and mechanical contacts, converting signals into isolated relay outputs—ideal for Zone 0/1 control systems 


Key Features

  • Input: NAMUR digital or mechanical signals

  • Channels: 2 independently isolated channels

  • Power Supply: 115 V AC or 230 V AC variants 

  • Outputs: SPDT relay contacts (250 V AC / 2 A) per channel 

  • Lead‑Break Monitoring: Detects sensor cable faults

  • DIN‑Rail Housing: Compact W2 form, IP20 rated

  • Status LEDs: Visual power and channel activity


Specifications
