All variants share the same BOS 21M-NA-PR10-S4 footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
The BOS00TH is the device-level element in a Balluff industrial component installation. It receives the field signals and control supply listed above — 10 ... 30 VDC — 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.
Q.What supply does this device require?
It requires 10 ... 30 VDC. Size the supply source to the same rating shown in the Specifications table.
Q.What I/O or output configuration does it provide?
It provides NPN, NO/NC (2 outputs, switchable). Match this to the existing wiring before substituting.
Q.What is the operating temperature range?
The confirmed operating range is -5 ... +55 C. Panels running beyond it need derated sizing.
Q.What replaces a unit that is no longer in production?
For a like-for-like spare, record the catalog number and revision from the nameplate; a current-production equivalent is identified by matching function and ratings.
