ABB · PLC controller
PM633 is an ABB PLC controller with Supply voltage 24 V DC (IEC 61131-2); Enclosure rating IP20 (IEC 60529); Communication ports Modbus, PROFINET, Ethernet. It is used in packaging machines, conveyor transfer cells, small process skids where the installed unit is matched to the original catalog number and a compact, documented part is required.

All variants share the same PLC controller footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
Where it sits in the control system
The PM633 is the device-level element in an ABB PLC controller 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 packaging machines, conveyor transfer cells, small process skids, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Before you specify
-
Ratings. Confirm the rated current and voltage match the circuit before specifying; sizing from the nameplate avoids field mismatch.
-
Mounting. Check the 35 mm DIN rail (IEC 60715) fit against the existing enclosure before ordering.
-
Marking. Record the catalog number and revision from the nameplate of the installed unit for a like-for-like spare.
Technical FAQ
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 35 mm DIN rail (IEC 60715). 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.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.
