Where it sits in the control system
The EL6900 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 EL6900
Beckhoff EL6900 — 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 EL6900; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Certifications: CE, UL, cULus — Check this value against the nameplate of the installed unit before ordering.
- Dimensions (H x W x D): 12 mm x 100 mm x 68 mm — Match it to the existing panel and upstream protection.
- Weight: approx. 50 g — 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.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Common questions about EL6900
Q.Before ordering EL6900, which bus interface entry should be checked?
