Delta DOP-300 HMI — Smart Touch Panel for Industrial Automation
The Delta DOP-300 HMI is a next-generation human-machine interface designed for modern industrial automation, smart manufacturing, and IIoT applications. Specifically, DOP-300 touch panel combines a high-performance processor, 24-bit color display, dual Ethernet connectivity, and support for advanced communication protocols such as MQTT and OPC UA.
Furthermore, with 7-inch and 10.1-inch display options, the DOP-300 Series provides a practical interface for machine operation, production monitoring, and industrial data visualization. In addition, its connectivity with Delta DIACloud and DIAWebDesigner makes it suitable for applications that require remote monitoring and connected automation.
DOP-300 Series Models
The DOP-300 Series offers compact HMI solutions for different machine and automation requirements. Two popular models are the DOP-3S07S3E2 and DOP-3S10S3E2.
DOP-3S07S3E2 — 7 Inch Delta HMI
The DOP-3S07S3E2 is a 7-inch HMI designed for applications where panel space is limited but a clear and responsive operator interface is required. This 7 inch Delta HMI can be used for machine control, equipment monitoring, parameter adjustment, alarm management and production data visualization.
Its compact form factor makes it suitable for control panels, packaging machines, material handling systems and other industrial equipment.
DOP-3S10S3E2 — 10.1 Inch Delta HMI
For applications requiring a larger visualization area, the DOP-3S10S3E2 provides a 10.1-inch display. This 10 inch Delta HMI offers more screen space for process information, alarms, trends, dashboards and multiple machine parameters.
Therefore, it is a suitable option for larger machines and applications where operators need to view more information on a single screen.
Software for HMI Development
Software plays an important role in configuring and developing HMI applications. Delta provides dedicated tools for designing interfaces, configuring communication, and managing HMI projects.
DIAScreen — HMI Project Development
For users working with Delta HMI platforms, DIAScreen software provides the environment required for HMI project development and configuration. You can use it to create screens, add objects, configure tags, and develop operator interfaces.
DIAWebDesigner — Web-Based Interface Design
The DOP-300 ecosystem also supports DIAWebDesigner DOP-300, a web-based interface development solution designed for creating customized interfaces and monitoring important equipment data.
Programming Manual & Documentation
If you are searching for a DOP-300 programming manual PDF, use the latest documentation available from Delta. This helps ensure that the software version, communication settings, and supported functions match your HMI model.

Delta DOP-300 HMI — IIoT & Cloud Connectivity
The Delta DOP-300 touch panel is built for industrial connectivity, and it supports MQTT and OPC UA to connect machine-level information with modern industrial networks and IIoT systems.
Delta DOP-300 MQTT Setup
Seamless data exchange. You can use MQTT to exchange industrial data between connected devices and applications. In a typical Delta DOP-300 MQTT setup, you configure the MQTT communication parameters, server information, and required data tags according to your automation architecture.
Delta DOP-300 OPC UA
Modern industrial communication. The Delta DOP-300 OPC UA capability meets modern industrial communication requirements. Moreover, OPC UA helps you integrate HMI data with compatible automation systems, software platforms, and higher-level monitoring applications.
DIACloud Remote Monitoring — Delta HMI
Real-time cloud visibility. The Delta HMI DIACloud remote monitoring ecosystem connects equipment data with cloud-based monitoring solutions. As a result, machine builders and end users gain remote access, monitor equipment, and track production visibility in real time.
Wireless Connectivity — Delta HMI 4G LTE Antenna
Connect anywhere. For wireless applications, the DOP-300 platform supports wireless connectivity options. In addition, you can use a Delta HMI 4G LTE antenna and a compatible communication module to extend connectivity where wired networking is not practical.
Technical Specifications
The DOP-300 Series combines display performance with industrial networking features. It is designed to provide a clear operator interface while supporting connected automation applications.
Key features include:
- 7-inch and 10.1-inch display options
- 24-bit true color display
- Wide viewing angle
- Full-lamination panel design
- High-performance dual-core ARM-based processing
- Dual Ethernet ports for network integration
- Support for MQTT and OPC UA
- Wi-Fi and 4G connectivity options
- DIACloud connectivity
- DIAWebDesigner support
DOP-300 dual Ethernet HMI
The DOP-300 dual Ethernet HMI configuration can simplify network integration where separate connections are useful for machine and higher-level networks. The DOP-300 IP66 HMI design is also relevant for industrial environments where protection against dust and water is required. Always verify the exact protection rating and specifications for the selected model before installation.
The display uses 24-bit true color technology for clear visualization. Furthermore, the high-performance ARM-based processor helps the HMI handle demanding visualization and connectivity requirements.
Compliance & Industry Applications
Modern industries often require more than basic machine operation. They also need traceability, data management and controlled access.
The DOP-300 platform can support applications where electronic records and data integrity are important. For example, Delta provides resources related to FDA 21 CFR Part 11 functions for applicable DOP-300 applications.
This makes the platform relevant for automation projects in regulated environments. Potential applications include Delta HMI pharmaceutical systems, packaging equipment, process machinery and Delta HMI food industry applications.
However, compliance requirements depend on the complete system, software configuration and validation process. Therefore, users should verify the applicable requirements before selecting the HMI for a regulated application.
PLC Communication
A reliable HMI must communicate effectively with PLCs and other industrial devices. The DOP-300 Series is designed for integration with multiple automation systems and communication architectures.
Depending on the selected protocol and device, users can configure Delta HMI Modbus TCP communication for connecting compatible PLCs and industrial equipment. The platform also supports Delta HMI EtherNet/IP communication for suitable network applications.
The HMI can be integrated into automation systems involving PLC platforms from manufacturers such as Siemens, Mitsubishi and Omron, subject to supported communication drivers and configuration requirements.
This flexibility makes the DOP-300 suitable for machine builders, system integrators and industrial automation engineers working with different control architectures.
