Series Overview
Series Overview
CP1H is a mature OMRON compact PLC family with a substantial installed base in machinery and production lines. CPU type, I/O configuration and power supply must be matched for MRO replacement.
Part-number Structure & Selection Notes
When purchasing, confirm the CPU type, built-in I/O, analog requirements, power supply and output mode. For existing equipment, the compatibility of expansion units, programs and communication boards should also be checked before replacement.
Models in This Series
The table lists commonly requested models and key specifications. If your required model is not shown, send the complete ordering code for verification.
| Complete Part Number | type | key notes |
|---|---|---|
| CP1H-X40DR-A | X type | 40 I/O / AC supply / relay output |
| CP1H-X40DT-D | X type | 40 I/O / DC supply / NPN (sinking) transistor output |
| CP1H-X40DT1-D | X type | 40 I/O / DC supply / PNP (sourcing) transistor output |
| CP1H-XA40DR-A | XA type | 40 I/O / AC supply / relay output / built-in analog I/O |
| CP1H-XA40DT-D | XA type | 40 I/O / DC supply / NPN transistor / built-in analog I/O |
| CP1H-XA40DT1-D | XA type | 40 I/O / DC supply / PNP transistor / built-in analog I/O |
| CP1H-Y20DT-D | Y type | 20 I/O class / DC supply / NPN transistor / positioning-oriented |
The CP1H family comprises seven official CPU models. Selection must follow OMRON ordering data; unverified variants must not be inferred from naming patterns.
Specifications must be confirmed against the applicable official datasheet and ordering information. Regional variants, suffixes and configurations are not automatically interchangeable.
FAQ
Frequently Asked Questions
How do I confirm the complete part number for CP1H PLC?
When purchasing, confirm the CPU type, built-in I/O, analog requirements, power supply and output mode. For existing equipment, the compatibility of expansion units, programs and communication boards should also be checked before replacement.
What are the main differences between CP1H-X40DT-D and CP1H-X40DR-A?
key notes: CP1H-X40DT-D is 40-point / transistorvariant, CP1H-X40DR-A is 40-point / relayvariant. Verify the complete ordering code and project conditions before selection or replacement; the series name alone is not sufficient.
Which specifications matter most when selecting CP1H PLC?
Key specifications to verify are type, key notes. Match them against the equipment nameplate, drawing or original model, and retain every suffix, option and regional code in the complete ordering reference.
Why is the complete part number required when requesting a quote for CP1H PLC?
Models within CP1H PLC may differ in electrical ratings, construction, interfaces or accessories. For example, CP1H-X40DT-D, CP1H-X40DR-A, CP1H-XA40DT-D are distinct configurations and cannot be interchanged on the series name alone. Using the complete part number substantially reduces mismatch risk.
