Where it sits in the control system
The EL6731 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 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 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 EL6731
Beckhoff EL6731 — 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 EL6731; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Storage temperature: -40…+85°C — Verify it in the project documentation before confirming the order.
- Breaking capacity Icu/Ics: status LEDs — Check this value against the nameplate of the installed unit before ordering.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Match it to the existing panel and upstream protection.
- Dimensions (H x W x D): 24 mm x 100 mm x 52 mm — Record it with the other nameplate data when sourcing a replacement.
Cross-check the ratings above with the installed device before confirming the order.
Common questions about EL6731
Q.Which value is published under weight for catalog number EL6731?
For EL6731, weight is given as approx. 70 g. Confirm this figure against the unit currently in the panel.
Q.Before ordering EL6731, which dimensions (H x W x D) entry should be checked?
The dimensions (H x W x D) entry quoted above is 24 mm x 100 mm x 52 mm. Use the value as the reference when sourcing a current-production equivalent.
Q.Where can I find the supply voltage data for EL6731?
It is listed in the specification table for Beckhoff EL6731 as 24 V DC (IEC 61131-2). Check the revision of the installed unit if the catalog number has been superseded.
Q.How do I confirm compatibility of EL6731 before ordering?
Match the catalog number EL6731 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 EL6731 replace the unit currently installed in my panel?
Compare catalog number EL6731 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.
