Where it sits in the control system
The X20SI9100 is the device-level element in a B&R 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 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 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 Industrial X20SI9100
Industrial X20SI9100 — 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 X20SI9100; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Enclosure rating: IP20 (IEC 60529) — Match it to the existing panel and upstream protection.
- Bus interface: 0.4 W — Record it with the other nameplate data when sourcing a replacement.
- Rated insulation voltage Ui: 500 V eff — Confirm the revision of the installed unit before a like-for-like replacement.
- Communication ports: POWERLINK, Ethernet — Use it as the reference when cross-checking a current-production equivalent.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
Common questions about X20SI9100
Q.Where can I find the communication ports data for X20SI9100?
It is listed in the specification table for Industrial X20SI9100 as POWERLINK, Ethernet. Compare it with the nameplate of the installed unit before ordering.
Q.For X20SI9100, what does the specification table state about input type?
The specification table lists input type = Sink for Industrial X20SI9100. Confirm this figure against the unit currently in the panel.
Q.Which value is published under bus interface for catalog number X20SI9100?
For X20SI9100, bus interface is given as 0.4 W. Use the value as the reference when sourcing a current-production equivalent.
Q.How do I confirm compatibility of X20SI9100 before ordering?
Match the catalog number X20SI9100 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 X20SI9100 replace the unit currently installed in my panel?
Compare catalog number X20SI9100 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.
