Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The AL1331 is the device-level element in an IFM circuit breaker installation. It receives the field signals and control supply listed above — 20...28 V DC (IEC 61131-2) — and switches or conditions the load within the <= 440 V AC 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.
IFM AL1331 — 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 AL1331; record the nameplate data of the unit being replaced before selecting an equivalent.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Q.For AL1331, what does the specification table state about rated operational voltage?
The specification table lists rated operational voltage = <= 440 V AC for IFM AL1331. Compare it with the nameplate of the installed unit before ordering.
Q.Which value is published under communication ports for catalog number AL1331?
For AL1331, communication ports is given as Ethernet; IO-Link. Confirm this figure against the unit currently in the panel.
Q.Before ordering AL1331, which certifications entry should be checked?
The certifications entry quoted above is CE, cULus. Use the value as the reference when sourcing a current-production equivalent.
Q.Can the AL1331 replace the unit currently installed in my panel?
Compare catalog number AL1331 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.How do I confirm compatibility of AL1331 before ordering?
Match the catalog number AL1331 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
