Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The Q04UDVCPU is the device-level element in a Mitsubishi 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.
Selection notes for Mitsubishi Q04UDVCPU
Mitsubishi Q04UDVCPU — PLC / CPU module used as the device-level control core in an automation panel, handling logic, timing and communication tasks. The figures below are taken from the specification table on this page for catalog number Q04UDVCPU; record the nameplate data of the unit being replaced before selecting an equivalent.
- Mounting: 35 mm DIN rail (IEC 60715) — Record it with the other nameplate data when sourcing a replacement.
- Supply voltage: 24 V DC (IEC 61131-2) — Confirm the revision of the installed unit before a like-for-like replacement.
- Total I/O: 4096 — Use it as the reference when cross-checking a current-production equivalent.
- Certifications: CE, UL, cULus — Verify it in the project documentation before confirming the order.
For a discontinued unit, match function and electrical ratings rather than the label alone.
