New open-platform HMIs offer SCADA versatility, Web-based features, and UL certification
Maple Systems, manufacturer of industrial operator interface products, released two new UL-listed Touchscreen Open HMIs, 7- and 10-inch high-resolution widescreens that run a pre-installed version of MS Windows CE. Maple says these units fit the bill when you need more capability and versatility than a standard HMI, but don’t need or have the budget for a full-scale industrial panel PC.
The 16:9 widescreen high-resolution displays of these new additions offer 30% more viewing area than standard 4:3 screens of similar size, which allows more room for applications, graphics, text, buttons, and other graphics. The clarity of those graphics is augmented by the 800 x 400 pixel screen resolution, 65 thousand colors of the LED display, and the RISC processor that handles graphic rich applications. Windows CE is more affordable and requires less ram than XP, and so with 128 MB of flash memory and 64 MB of DRAM, the 400 MHz 32 Bit RISC processor can provide quick application response times.
Providing enhanced connectivity, these open HMIs come with an Ethernet port, USB ports, three serial COM ports, an SD card slot, and an audio jack. With this enhanced connectivity and the resident web browser of Windows CE, these new arrivals grant you the versatility and capability that you would normally find in units costing thousands more. And the hardware can be enhanced by connecting an external keyboard, mouse, printer, and external speakers. With their preloaded web browser, Ethernet connectivity, and optional Web Studio Software, these Open HMIs are fully capable of remote data entry, remote monitoring, and scenarios that require support for multiple devices.
These units are CE certified, RoHS compliant , and UL listed for both Canada and the U.S. They can withstand operation in temperatures ranging from 32 to 113 °F (0 to 45 °C) without a cooling fan, and operate in a non-condensing relative humidity range of 10 to 90%. They can even withstand the rigors of water jet spraying when properly installed into a NEMA4 rated panel.
