The LR-ZH490CB is the device-level element in a Keyence industrial component installation. It receives the field signals and control supply listed above — 10...30 V DC (IEC 60947-5-2) — 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 control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides standard panel or DIN-rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.

The figures below are taken from the specification table on this page for catalog number LR-ZH490CB; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
Available from stock with datasheet, certificates and a quotation on request.
Q.Where can I find the humidity data for LR-ZH490CB?
It is listed in the specification table for Keyence LR-ZH490CB as 35 to 85 % RH (No condensation). Confirm this figure against the unit currently in the panel.
Q.For LR-ZH490CB, what does the specification table state about resolution?
The specification table lists resolution = 1 to 5 (1 to 5 mm 0.04" to 0.20" ) for Keyence LR-ZH490CB. Use the value as the reference when sourcing a current-production equivalent.
Q.Which value is published under supply voltage for catalog number LR-ZH490CB?
For LR-ZH490CB, supply voltage is given as 10...30 V DC (IEC 60947-5-2). Check the revision of the installed unit if the catalog number has been superseded.
Q.How do I confirm compatibility of LR-ZH490CB before ordering?
Match the catalog number LR-ZH490CB 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 LR-ZH490CB replace the unit currently installed in my panel?
Compare catalog number LR-ZH490CB 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.
