Where it sits in the control system
The EL3255 is the device-level element in a Beckhoff industrial component installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — 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 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Beckhoff EL3255
Beckhoff EL3255 — 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 EL3255; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Enclosure rating: IP20 (IEC 60529) — Record it with the other nameplate data when sourcing a replacement.
- Mounting: 35 mm DIN rail (IEC 60715) — Confirm the revision of the installed unit before a like-for-like replacement.
- Bus interface: typ. 80 mA — Use it as the reference when cross-checking a current-production equivalent.
- Tripping characteristic: 8…9 mm — Verify it in the project documentation before confirming the order.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Common questions about EL3255
Q.Which value is published under mounting for catalog number EL3255?
For EL3255, mounting is given as 35 mm DIN rail (IEC 60715). Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering EL3255, which operating temperature entry should be checked?
The operating temperature entry quoted above is 0...+55 °C (IEC 60068-2-1). Confirm this figure against the unit currently in the panel.
Q.Where can I find the storage temperature data for EL3255?
It is listed in the specification table for Beckhoff EL3255 as -40…+85°C. Use the value as the reference when sourcing a current-production equivalent.
Q.What should I include in an enquiry for EL3255?
Send the full catalog number EL3255, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for Beckhoff EL3255.
Q.How do I confirm compatibility of EL3255 before ordering?
Match the catalog number EL3255 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
