eSMART04 is the basic HMI designed to offer an outstanding price/performance ratio for challenging applications.

It's the ideal choice for HMI applications including industrial and building automation. eSMART04 features a bright 4 inch resistive touchscreen display with a fully dimmable LED backlight.

No low cost HMI can offer features and certificates as eSMART04, such as ATEX and UL, opening dramatically the range of possible applications/industry verticals.



The eSMART series of products combine the power of JMobile – the software inside X Platform with an outstandingly robust design.With very specific applications in mind we have stripped down the eSMART to only the essential components and have created a truly class leading product.

Stripped down does not mean that the product is not robust. In fact it maintains a IP66 protection rating for the front of the unit and is certified to a level not seen in the low cost sector worldwide, allowing use in the most hazardous of environments.

Stripped down does not mean a cheap looking ugly product. The eSMART series is without doubt the most elegant in its class. No other fully plastic housed product can match the eSMART quality.

Stripped down does not mean reduction in high level functionality. Although the display is not at the incredible real life level of the eX700 series, the unique connectivity ability of JMobile – the software inside X Platform, allows the eSMART to communicate with a vast library of critical protocols as well as OPC UA standard and pub/sub server and client.
