Where it sits in the control system
The 6AV2123-2GB03-0AX0 is the device-level element in a Siemens HMI panel installation. It receives the field signals and control supply listed above — 24 V DC (IEC 60950-1) — 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 machine operator panels, control cabinets, local HMI stations, where the unit is matched to the original catalog number and the enclosure provides Panel mount / DIN rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Siemens 6AV2123-2GB03-0AX0
Siemens 6AV2123-2GB03-0AX0 — Operator panel for visualisation, parameter setting and alarm handling on a control cabinet door or console. The figures below are taken from the specification table on this page for catalog number 6AV2123-2GB03-0AX0; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Enclosure rating: IP65 (IEC 60529) — Match it to the existing panel and upstream protection.
- Touch type: resistive or projective capacitive — Record it with the other nameplate data when sourcing a replacement.
- Mounting: Panel mount / DIN rail — Confirm the revision of the installed unit before a like-for-like replacement.
- Operating temperature: 0...+50 °C — 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.
