The 2902028 is the device-level element in a Phoenix Contact industrial component installation. It receives the field signals and control supply listed above — 11...30 V DC (loop powered) — and switches or conditions the load within the the rated ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides DIN rail mounting support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Phoenix Contact 2902028 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings. The figures below are taken from the specification table on this page for catalog number 2902028; record the nameplate data of the unit being replaced before selecting an equivalent.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Q.For 2902028, what does the specification table state about rated insulation voltage Ui?
The specification table lists rated insulation voltage Ui = 300 V rms for Phoenix Contact 2902028. Check the revision of the installed unit if the catalog number has been superseded.
Q.Which value is published under enclosure rating for catalog number 2902028?
For 2902028, enclosure rating is given as IP66 / IP67 (IEC 60529). Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering 2902028, which power consumption entry should be checked?
The power consumption entry quoted above is ≤ 1 W (at I OUT = 20 mA, 9.6 V DC, 600 Ω load). Confirm this figure against the unit currently in the panel.
Q.What should I include in an enquiry for 2902028?
