Where it sits in the control system
The 2900938 is the device-level element in a Phoenix Contact industrial component installation. It receives the field signals and control supply listed above — the rated supply — 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 / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Phoenix Contact 2900938
