High Light Delta DOP-300 IIoT HMI touch screen ,10 inch Ethernet HMI with Wi-Fi ,MQTT compatible HMI touch screen
Delta DOP-300 Series IIoT HMI
The Delta DOP-300 Series is an advanced human machine interface built for the Industrial Internet of Things, available in 7-inch and 10.1-inch sizes. It features an ARM Cortex-A7 dual-core processor at 1.2 GHz with 512 MB Flash ROM and 512 MB RAM — twice the memory of DOP-100 basic models — ensuring rapid screen changes and system responsiveness.
The display is a 24-bit full-colour 1024 x 600 widescreen at 400 cd/m² brightness with an 85/85/85/85 (170° ultra-wide) viewing angle, paired with an IPS fully laminated panel and narrow-bezel design — eliminating air gaps between glass and panel to reduce reflections and improve both light transmission and touch sensitivity.
Key connectivity features include two 10/100 Mbps auto-detection Ethernet ports, each with isolated circuits for stable communication across different ground potentials. Wireless capabilities are supported through a built-in antenna and detachable Wi-Fi and 4G communication modules. The device supports MQTT and OPC UA protocols alongside Modbus and EtherNet/IP for seamless cloud integration.
Product Highlights
  • ARM Cortex-A7 dual-core at 1.2 GHz — significant performance upgrade from DOP-100 basic models
  • 512 MB Flash ROM + 512 MB RAM — double the capacity for complex screen operations

Frequently Asked Questions
What is the difference between the DOP-300 and the DOP-100 series?
The DOP-300 is the advanced IIoT series. Key differences: (1) processor — Cortex-A7 dual core at 1.2 GHz versus Cortex-A8 single core at 800 MHz on DOP-100 basic models; (2) memory — 512 MB Flash + 512 MB RAM versus 256 MB + 256 MB; (3) networking — two isolated Ethernet ports versus no Ethernet on basic models; (4) wireless — built-in antenna with Wi-Fi / 4G module support; (5) protocols — MQTT and OPC UA support; (6) display — 24-bit full colour, IPS fully laminated, 170° viewing angle. For local operation and serial communication only, the DOP-100 is more economical; for cloud or MES connectivity, choose the DOP-300.
What are MQTT and OPC UA for?
These are dominant industrial IoT protocols. MQTT is lightweight and suited to bandwidth-constrained networks — commonly used to push device data to cloud platforms. OPC UA carries semantic data modelling and security mechanisms, making it ideal for exchanging structured data with MES and SCADA systems. Supporting both ensures the DOP-300 isn't tied to one vendor's cloud service and can connect to existing IoT platforms — particularly important for OEM export machinery.
Are the Wi-Fi / 4G modules standard or optional?
The housing has a built-in antenna design and accepts detachable wireless communication modules. The modules themselves are optional — where wireless is needed, add the module rather than replacing the unit. For sites with difficult cabling or mobile equipment, specify module requirements and regional certification during quotation.
Is there an extra cost for cloud data?
DIACloud is Delta's cloud service platform and DIAWebDesigner is a web-based editor requiring no local installation. Confirm cloud service pricing and licensing with Delta or an authorized distributor — this page makes no claims about price or free-tier allowances. Third-party sources have mentioned annual cloud license tiers, but this is not officially confirmed.
How are the two Ethernet ports used?
Two typical approaches: (1) Network segmentation — one port connects device-level network (PLCs, drives) and the other connects plant control network, with isolation to avoid broadcast interference; (2) Redundancy or load splitting — link redundancy for critical applications. Both ports have isolated circuits, which is crucial where cabling crosses distribution cabinets with different ground potentials.
Which industries suit the DOP-300 best?
Delta officially recommends equipment requiring cloud-based remote monitoring, such as air compressors and water pumps, and the medical, pharmaceutical, and food and beverage industries. Selection logic: if the machine needs to send data to cloud, MES, or customer platforms — choose DOP-300; if only local operation and serial communication are needed — DOP-100 series is more economical.
