Where it sits in the control system
The EL2809 is the device-level element in a Beckhoff circuit breaker 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 24 V DC (-15%/+20%) 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 distribution boards, motor protection circuits, panel feeders, 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 EL2809
Beckhoff EL2809 — 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 EL2809; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Rated operational voltage: 24 V DC (-15%/+20%) — Record it with the other nameplate data when sourcing a replacement.
- Breaking capacity Icu/Ics: typ. < 2 A — Confirm the revision of the installed unit before a like-for-like replacement.
- Tripping characteristic: 8…9 mm — Use it as the reference when cross-checking a current-production equivalent.
- Supply voltage: 24 V DC (IEC 61131-2) — 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 EL2809
Q.Before ordering EL2809, which storage temperature entry should be checked?
The storage temperature entry quoted above is -40…+85°C. Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the bus interface data for EL2809?
It is listed in the specification table for Beckhoff EL2809 as typ. 140 mA. Compare it with the nameplate of the installed unit before ordering.
Q.For EL2809, what does the specification table state about dimensions (H x W x D)?
The specification table lists dimensions (H x W x D) = 12 mm x 100 mm x 68 mm for Beckhoff EL2809. Confirm this figure against the unit currently in the panel.
Q.How do I confirm compatibility of EL2809 before ordering?
Match the catalog number EL2809 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
Q.Can the EL2809 replace the unit currently installed in my panel?
Compare catalog number EL2809 and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
