DC-to-DC variations

DC-to-DC variations

Three of Phoenix Contact’s DC/DC versions are dipped in conformal coating, seven are not.

Conformal coating

The three conformal-coating dipped versions are listed for use in Class I Division 2, Groups A/B/C/D areas. These three devices also have system-level approvals for ATEX and IECEx.  All three of these products accept a 24 V input and provide a 24 V output. The power outputs range from 120 W to 480 W.

Non-conformal coating

The seven non-conformal-coating dipped versions are listed for use in Class I Division 2, Groups A/B/C/D areas; however they are not approved for use where IECEx or ATEX is a requirement.

Class I, Division 2

Class I, Division 2
All ten of these DC-to-DC part numbers are listed in UL File: E199827.
Each is cULus listed as:

  • Process control equipment
  • Class I, Division 2, Groups A/B/C/D
  • T4
  • Hazardous locations
  • 31ZN
Back to top

Part numbers 2320542, 2320555, and 2320568 are the only ones that can be used in applications with an IECEx or ATEX requirement. These three have a device level approval with the following markings:

  • TuV 13 ATEX 090  493X
  • II 3G Ex nA IIC T4 Gc
  • IECEx TUN 13.0007X
  • Ex nA nC IIC T4 Gc

Conformal coating (dipped)

The printed circuit boards for part numbers 2320542, 2320555, and 2320568 are completely submerged in moisture-proofing coating. The coating is added to allow for a device-level IECEx/ATEX certification. In addition to the device-level approval, the following benefits are also realized:

  • Resistance to moisture/salt spray
  • Resistance to corrosive atmospheres/gases
  • Resistance to conductive debris
  • Improved shock and vibration specifications
