Where it sits in the control system
The EL4004 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 EL4004
Beckhoff EL4004 — 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 EL4004; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Communication ports: EtherCAT, Ethernet — Verify it in the project documentation before confirming the order.
- Weight: approx. 85 g — Check this value against the nameplate of the installed unit before ordering.
- Mounting: 35 mm DIN rail (IEC 60715) — Match it to the existing panel and upstream protection.
- Bus interface: typ. 140 mA — Record it with the other nameplate data when sourcing a replacement.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Common questions about EL4004
Q.Which value is published under operating temperature for catalog number EL4004?
For EL4004, operating temperature is given as 0...+55 °C (IEC 60068-2-1). Use the value as the reference when sourcing a current-production equivalent.
Q.Before ordering EL4004, which mounting entry should be checked?
The mounting entry quoted above is 35 mm DIN rail (IEC 60715). Check the revision of the installed unit if the catalog number has been superseded.
Q.Where can I find the supply voltage data for EL4004?
It is listed in the specification table for Beckhoff EL4004 as 24 V DC (IEC 61131-2). Compare it with the nameplate of the installed unit before ordering.
Q.How do I confirm compatibility of EL4004 before ordering?
Match the catalog number EL4004 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 EL4004 replace the unit currently installed in my panel?
Compare catalog number EL4004 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.
