The Delta DOP-100 Series is a family of industrial Human Machine Interfaces designed for machine visualization, operator control and communication with automation equipment.
For industrial buyers and maintenance teams, however, selecting a DOP-100 HMI requires more than simply choosing a screen size. Different models within the series can have different communication interfaces, display specifications, hardware configurations and application features.
This guide provides a practical overview of the Delta DOP-100 Series and explains the key information buyers should confirm when selecting a new HMI or sourcing a replacement.
What Is the Delta DOP-100 Series?
The Delta DOP-100 Series is designed to provide the interface between operators and industrial automation systems. Depending on the model and application, the HMI can be used to visualize machine information, adjust operating parameters and communicate with connected automation equipment.
Typical HMI functions can include:
- Machine status visualization
- Process value display
- Parameter adjustment
- Alarm management
- Historical data display
- User authority management
- Communication with controllers and other automation devices
Delta divides the DOP-100 Series into four main categories: Basic, Standard, Advanced and Handheld HMI. These categories are designed for different machine and application requirements.
Do not select a DOP-100 HMI by screen size alone
Two Delta HMIs with similar display sizes may have different communication interfaces, networking capabilities or hardware configurations.
Before ordering, buyers should confirm:
- Complete model number
- Display size and resolution
- Communication interfaces
- Ethernet requirements
- Existing PLC or controller
- Existing HMI project, when replacing a unit
Understanding the DOP-100 HMI Categories
The DOP-100 Series is not a single HMI specification. Different product categories are available for different levels of communication, functionality and machine operation.
Basic HMI
Delta identifies S Type, B Type and D Type within the Basic HMI category. Basic models provide the fundamental functions required for many industrial HMI applications.
They can be suitable for applications where the main requirement is straightforward machine visualization and operator interaction without the additional communication functions required by more complex systems.
Standard HMI
Delta identifies C Type, P Type, E Type and I Type within the Standard HMI category. Standard models provide broader communication configurations for industrial applications.
According to Delta, Standard HMIs provide three serial communication ports, while applicable Standard Ethernet models also provide Ethernet connectivity.
Advanced HMI
Delta identifies W Type and M Type within the Advanced HMI category. Advanced models are intended for applications requiring enhanced communication and functionality.
Delta's 12-inch and 15-inch Advanced models use a dual-core Cortex-A7 1 GHz processor. The Advanced category also provides multiple serial communication ports and Ethernet connectivity.
Handheld HMI
The Handheld category is designed for applications where the operator interface needs to be portable. Delta's DOP-100 Handheld HMI uses a 7-inch display and is designed for machine operation, monitoring and motion-teaching applications.
The correct category depends on the machine, communication requirements and operating environment. The exact model should still be verified before ordering.
Why the Exact DOP-100 Model Number Matters
When sourcing a Delta HMI, the complete model number is much more useful than a general description.
Compare these two requests:
“I need a Delta 7-inch HMI.”
Several Delta HMI models may have a similar display size but different communication or hardware configurations.
Brand: Delta
Model: DOP-107DV
Quantity: 2 pcs
Destination: Mexico
The second request provides enough information to begin checking the exact product requirement.
Examples of models found within the DOP-100 family include:
- DOP-103BQ
- DOP-103DQ
- DOP-105CQ
- DOP-107BV
- DOP-107CV
- DOP-107DV
- DOP-107EG
- DOP-107EV
- DOP-107H
- DOP-107IV
- DOP-108IG
- DOP-110CG
- DOP-110CS
- DOP-110IG
- DOP-110IS
- DOP-112WX
- DOP-115WX
Always provide the complete model and suffix
Similar model names do not automatically indicate identical specifications. When possible, provide the complete model exactly as shown on the product nameplate.
For an existing machine, a clear photo of the HMI and its nameplate can also help confirm the purchasing requirement.
Communication Options Matter
Communication is one of the most important areas to check when selecting or replacing an HMI.
Depending on the DOP-100 model, communication options can include serial communication and Ethernet connectivity. The available configuration varies by product type and exact model.
Delta states that Standard HMIs provide three serial communication ports, while Standard Ethernet types provide Ethernet connectivity. Advanced models provide multiple serial communication ports together with Ethernet.
Check the existing communication configuration
Before sourcing a replacement HMI, confirm:
- Existing HMI model
- PLC or controller model
- Serial communication requirements
- Ethernet requirements
- Existing communication cable
- Connected automation equipment
- Existing HMI project file
A physically similar touchscreen is not automatically a direct replacement.
DOP-100 Programming Software & Project Considerations
Software is another important consideration when selecting or replacing an industrial HMI.
Delta currently identifies DIAScreen as its HMI programming environment for the DOP-100 Series. The software provides interface design functions together with features for alarms and user authority management.
For maintenance and replacement projects, the existing HMI project can be especially important. Replacing the hardware does not automatically mean that the original project, communication settings and machine configuration can be ignored.
Before replacing an existing HMI, review both the physical hardware requirement and the software/project requirement.
Replacing an Older Delta HMI
One common purchasing requirement is replacing an older or discontinued Delta HMI installed on an existing machine.
A practical replacement workflow is:
Delta states that the older DOP-B Series has been replaced by the DOP-100 Series and provides corresponding model guidance for compatible replacement projects.
Do not select a replacement only because:
- The screen size is the same
- The mounting dimensions appear similar
- Both products are Delta HMIs
- The newer model looks physically similar
The existing project, communication configuration and connected equipment may also affect the replacement process.
Information to prepare before sourcing a replacement
- Complete existing HMI model number
- Clear nameplate photo
- Connected PLC or controller model
- Communication interface
- Existing HMI project file, if available
- Required quantity
- Destination country
Which Delta DOP-100 HMI Should You Choose?
There is no single DOP-100 model that is appropriate for every machine. A practical selection process begins with the actual application and communication requirements.
| Requirement | Starting Point | What to Confirm |
|---|---|---|
| Basic machine interface | Basic HMI | Exact model and required functions |
| More communication requirements | Standard HMI | Serial ports and connected equipment |
| Ethernet required | Ethernet-capable model | Exact model and network requirement |
| Enhanced networking / functions | Advanced HMI | Interfaces, display and application |
| Portable machine operation | Handheld HMI | Machine and operating requirements |
| Existing machine replacement | Original exact model | Replacement, project and communication compatibility |
The HMI category is only the starting point. The exact product specification should still be verified before an order is placed.
A Better Way to Request a Delta DOP-100 Quotation
Buyers can reduce unnecessary back-and-forth communication by sending the main purchasing information together.
For a single Delta HMI, a useful RFQ format is:
For example:
If the exact model is uncertain, include clear photos of the existing HMI and its nameplate.
For replacement requirements, providing the connected PLC/controller model and information about the existing HMI project can also help clarify the requirement.
For multiple products, sending the complete BOM or purchasing list is usually more efficient than sending individual models one by one.
Consolidating the requirement allows the purchasing list to be reviewed as a whole.
