PW200XRD Power Supplier for ATEX 1 & 21 Zones

The PW200XRD is a robust intrinsic safety power supply unit designed to convert standard mains or DC voltages from safe areas into a certified intrinsically safe output voltage, enabling the safe powering of electronic devices installed in Zone 1 and Zone 21 hazardous areas. Engineered and certified to the ATEX directive, it is the ideal companion for Dini Argeo ATEX weighing systems.

Key Features

  • Converts 24 Vdc / 24 Vac / 115 Vac / 230 Vac input into a certified intrinsically safe output — select the model to match your supply voltage.
  • Housed in a rugged aluminium alloy Exd enclosure rated II 2GD Ex d IIC / Ex tD A21 IP66, suitable for Zone 1 gas and Zone 21 dust environments.
  • Supplied with a 3 m connection cable for direct integration with DFWATEX2GDxxx indicators.
  • Optional PW200IO module adds 4 intrinsically safe inputs and 4 configurable outputs (intrinsically safe or unprotected) for interfacing with the DFWATEXIO indicator and external devices such as relays in an Exd enclosure.
  • Designed and manufactured in compliance with EN 60079-0, EN 60079-11, and EN 60079-31 standards.
