Smart, Cost-Effective HMIs controls


Discover high-brightness, enclosure-ready EA HMI displays designed by Display Visions and distributed in the UK by MMS Electronics Ltd. Featuring versatile interfaces, Modbus, wide voltage supply and free design software.

In modern industrial automation, clear visual control interfaces are no longer a luxury—they are an operational requirement. However, control system engineers and OEM product designers frequently face a trade-off between expensive, rigid industrial HMIs and complex, time-consuming custom display integration.

Display Visions addresses this challenge with its EA HMI series, offering flexible, highly capable display solutions engineered to bridge the gap between high performance and cost efficiency. Distributed throughout the UK by MMS Electronics Ltd, these displays offer an economical alternative to traditional automation HMI suppliers without sacrificing features or build quality.

Ready-to-Install Industrial EA HMI Displays

The EA HMI display family provides an all-in-one solution designed for rapid integration into control panels, machinery, laboratory and factory environments. Supplied pre-assembled in rugged, protective enclosures, these HMIs eliminate the need for custom housing design or complex mechanical mountings.

Key Features & Technical Specifications

  • Versatile Display Sizes: Available with PCAP touch and screen sizes 2.8”, 4.3”, 7.0”, 10.1 and 12″ to suit various information densities.
  • Wide Input Voltage: Powered via a flexible 7V to 30V DC supply, making them directly compatible with standard 12V and 24V industrial control cabinets.
  • High-Brightness Displays: Engineered with sunlight-readable, high-luminance backlights to ensure maximum readability under bright industrial overhead lighting or outdoor conditions.
  • Multiple Interfaces: Versatile communication options— the series includes RS-232, RS-485, SPI, I²C, USB and Modbus—ensuring seamless connectivity with existing PLCs and field devices.
  • Economical Value: Provided at an attractive price compared to mainstream automation HMI brands.

Clear GUI Development with Free Design Software

Hardware capability means little without efficient software development tools. Display Visions supplies its HMI Designer and uniTFT Designer software free of charge with local support by MMS Electronics Ltd.

Engineers can create intuitive touch interfaces, visual gauges, trend graphs and interactive buttons using a simple drag-and-drop interface. Actions and command are connected to the visual buttons and I/O. The software includes built-in graphics libraries, object animation tools, many examples and simulation environments, drastically reducing software development cycles and speeding up time-to-market.

HMI with Integrated Modbus Master and Slave Support

EA HMIs models with Modbus RTU/TCP protocol are available. Having the advantage of functioning as a Modbus Master and a Modbus Slave.

By operating as a Modbus Master, the HMI can directly query industrial sensors, command variable frequency drives (VFDs), adjust digital controllers, and log process values—without requiring a central PLC.

This dual capability allows design engineers to build decentralized control architectures:

  • Standalone Operation: Use the HMI as the primary controller for smaller equipment setups.
  • System Integration: Function as a Modbus Slave to feed local operator input back to a PLC network.

EA uniTFT(s) Series for embedded solutions

For design engineers looking to build the displays directly into custom equipment or bespoke enclosures, Display Visions offers the EA uniTFT(s) product line distributed in the UK by MMS Electronics Ltd.

Unlike the panel-mount EA HMI enclosures, the EA uniTFT(s) series is supplied as an open-frame, board-level intelligent display module:

  • I/O Ready Architecture: Features built-in digital inputs/outputs, analogue inputs, and serial, SPI and I²C communication interfaces allowing hardware designers to build custom signal conditioning and I/O expansion boards around the display.
  • Fully Programmable: Uses the powerful, free uniTFTDesigner software to develop responsive, animated touch interfaces that in many cases allows the display to operate as a standalone controller or instrument.
  • Versatile Display Sizes: Available with PCAP touch and screen sizes 1.5”, 2.8”, 4.3”, 7.0”, 10.1″ to suit various information densities.
  • 3.3V Logic Supply: Designed to run most task on the display direct interfacing to modern microcontrollers, microprocessors, embedded systems and sensors.
  • Rapid Prototyping with EA DEMOPACK: To assist hardware developers in testing and evaluating the EA uniTFT(s) display performance complete evaluation kits EA DEMOPACK—are available from MMS Electronics Ltd.
