The 07CT41 is the device-level element in an ABB industrial component 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 control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides DIN rail / panel 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 24 V DC (IEC 61131-2). Size the supply source to the same rating shown in the Specifications table.
Q.How is this device mounted?
It mounts by DIN rail / panel. Confirm the cutout or rail before ordering a like-for-like spare.
Q.What is the operating temperature range?
The confirmed operating range is 0...+55 °C (IEC 60068-2-1). Panels running beyond it need derated sizing.
Q.Is this catalog number still in production, and what replaces it?
It is discontinued by the manufacturer; the current-production replacement is AC500. Cross-reference by function and ratings, not by label alone.
