Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 6AV123-2MB03-0AX0 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 (IEC 60529) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Siemens 6AV123-2MB03-0AX0 — 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 6AV123-2MB03-0AX0; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Q.For 6AV123-2MB03-0AX0, what does the specification table state about touch type?
The specification table lists touch type = resistive or projective capacitive for Siemens 6AV123-2MB03-0AX0. Check the revision of the installed unit if the catalog number has been superseded.
Q.Which value is published under operating temperature for catalog number 6AV123-2MB03-0AX0?
For 6AV123-2MB03-0AX0, operating temperature is given as 0...+50 °C. Compare it with the nameplate of the installed unit before ordering.
