OMRON PLC CP CP1H-X40DR-A CP1HX40DRA CP1H-X4ODR-A

Omron CP1H-X40DR-A Compact PLC CPU Unit

Overview

The CP1H-X40DR-A is a compact PLC CPU unit in the Omron CP1H family. Published product data shows 24 digital inputs, 16 relay outputs, 20K steps program capacity, 32K words data memory, 0.10 µs logic execution time, and USB communications in a single compact body.

It is part of the CP1H-X range, which Omron presents as a high-performance compact controller family with strong positioning and machine-control capability.

The controller is commercially useful because it sits in a very practical middle ground: it offers more performance than a basic micro PLC, but still keeps the simplicity of a compact integrated unit. In real automation work, that means a controller like this can handle digital machine control, relay-output field interfacing, and motion-related tasks without forcing a move to a larger rack system.

This is an engineering inference supported by the published CP1H-X family features, including high-speed counters and pulse-output capability in the X-series platform.

Technical Data

Application Value

The CP1H-X40DR-A fits well in packaging equipment, indexing systems, compact assembly machines, conveyors, utility skids, and OEM automation panels where a 40-point compact PLC is the right balance between capability and cabinet size.

Because the CP1H-X family is presented as a motion-capable compact controller platform, it is especially relevant in machines that need fast response, reliable sequential logic, and expansion without moving to a larger controller architecture.

This is an engineering inference based on the published CP1H-X family description and the built-in I/O profile of this exact model.

It also has strong installed-base value.

Product listings and Omron’s family material continue to present the CP1H-X40DR-A as a defined CPU model with relay outputs and expansion support, which makes it practical for users who want to preserve an existing Omron machine design instead of re-engineering the entire control section.

Replacement and Selection Perspective

For replacement work, the CP1H-X40DR-A should be matched by power type, I/O mix, relay output structure, and CPU family, not only by total point count.

In real panels, a relay-output CPU behaves differently from a transistor-output version, and the same is true for communications and expansion expectations. Matching the same CPU model usually keeps the original wiring and logic environment much closer to the machine’s existing design. 

This is an engineering recommendation grounded in the published AC supply, 24-in/16-relay-out configuration, and CP1H-X family role.

FAQ

Q1: What kind of controller is CP1H-X40DR-A?
It is a compact Omron PLC CPU unit with integrated digital I/O, relay outputs, and CPU functions in one body.

In practical terms, it serves as the main controller in compact machine systems rather than as a simple expansion module.

Q2: What applications fit it best?
It fits compact machinery, packaging systems, conveyors, utility automation, and OEM equipment where a moderate amount of built-in I/O and stronger compact-PLC performance are needed.

This is an engineering inference based on the published CP1H-X family positioning and the controller’s integrated 40-point format.

Q3: Why do relay outputs matter on this model?
Relay outputs are often preferred in mixed-load field environments because they are flexible and familiar in many legacy machines.

In replacement work, keeping the same relay-output structure usually reduces rewiring and preserves the original output-side behavior. 

This is an engineering inference based on the model’s published relay output configuration.

Q4: What gives the CP1H-X family more capability than a very basic compact PLC?
The X-series family is published as a higher-performance compact controller platform with features such as high-speed counters and pulse-output-based positioning support. That makes it suitable for more demanding machine-control tasks than a minimal-entry controller.

Q5: What should be checked before ordering?
Check the installed CPU code, confirm the AC supply, verify the 24-input / 16-relay-output structure, and make sure the machine is built around the same CP1H family and expansion concept.

Those points usually matter more than appearance alone.
