Where it sits in the control system
The EL3702 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 EL3702
Beckhoff EL3702 — 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 EL3702; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Storage temperature: -40…+85°C — Match it to the existing panel and upstream protection.
- Bus interface: typ. 200 mA — Record it with the other nameplate data when sourcing a replacement.
- Dimensions (H x W x D): 12 mm x 100 mm x 68 mm — 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.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Common questions about EL3702
Q.For EL3702, what does the specification table state about bus interface?
The specification table lists bus interface = typ. 200 mA for Beckhoff EL3702. Confirm this figure against the unit currently in the panel.
Q.Which value is published under weight for catalog number EL3702?
For EL3702, weight is given as approx. 60 g. Use the value as the reference when sourcing a current-production equivalent.
Q.Before ordering EL3702, which frequency entry should be checked?
The frequency entry quoted above is 80 kHz. Check the revision of the installed unit if the catalog number has been superseded.
Q.Can the EL3702 replace the unit currently installed in my panel?
Compare catalog number EL3702 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.
Q.What should I include in an enquiry for EL3702?
Send the full catalog number EL3702, the required quantity and a photo of the nameplate. Stock, lead time and the applicable compliance documents can then be confirmed for Beckhoff EL3702.
