Where it sits in the control system
The EL2004 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 EL2004
Beckhoff EL2004 — 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 EL2004; verify the catalog number against your bill of materials before requesting a quotation.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Verify it in the project documentation before confirming the order.
- Supply voltage: 24 V DC (IEC 61131-2) — Check this value against the nameplate of the installed unit before ordering.
- Weight: approx. 55 g — Match it to the existing panel and upstream protection.
- Output current: 0.5 A (short-circuit proof) per channel — Record it with the other nameplate data when sourcing a replacement.
