16:9 widescreen high-resolution displays offer 30 percent more viewing area
than the 4:3 standard screens of similar size. The 16:9 widescreen has a 800 x 400
pixel screen resolution, an LED display with 65 thousand colors and a RISC
processor that handles graphic rich applications - like Maple's SCADA software
- Web Studio. It also has 128 MB of Flash Memory, 64MB of DRAM and a 400 MHz 32
Bit RISC Processor for quick application response times.
The Open HMIs come with an
Ethernet Port, USB Ports, three Serial COM Ports, an SD Card Slot, an Audio
Jack and the resident web browser of Windows CE. The hardware can be enhanced
by connecting an external keyboard, mouse, printer, printer and external
The preloaded web browser,
Ethernet connectivity and optional Web Studio Software make the Open HMIs
capable of remote data entry and remote monitoring.
The units are CE certified,
RoHS Compliant and UL listed for both Canada and the US. These units can
withstand operation in temperatures ranging from 32 to 113F (0 to 45C) and they
can operate in a non-condensing relative humidity range of 10 to 90 percent. They
can also withstand the rigors of water jet spraying when properly installed into
a NEMA4 rated panel.
These models are fanless and
draw 12W of electricity, and produce less heat than a full-scale industrial
panel PC. They are useful for tight spaces or sealed environments where the
airflow needed for a panel PC's cooling fan would be more restrictive. The lack
of a cooling fan eliminates the damaging dust and particulates that would
otherwise be drawn into the circuitry.
