Pepperl+Fuchs Z728.H | Z‑System Zener Diode Barrier | 1‑Channel | 26.5 V | 80 mA | DIN‑Rail Mount

Overview

The Z728.H is a single‑channel Zener diode barrier from Pepperl+Fuchs’ Z‑System designed to protect equipment in hazardous zones. With DC non‑intrinsically safe input and positive polarity, this device limits voltage and current to safely interface between intrinsic safety and safe areas. Its compact DIN‑rail mount design and certifications make it suitable for industrial installations in zones 0, 1, 2, and division 1, 2 environments .


Key Features

  • Single‑channel DC barrier with positive polarity

  • Working voltage: 26.5 V at 10 µA 

  • Nominal/series resistance: 240 Ω (≤ 250 Ω max) 

  • Fuse rating: 80 mA 

  • DIN‑rail mounting for compact installation 

  • Industrial approvals: ATEX, IECEx, FM, cULus for zone/div safety
