Hazardous area HMIs offer choice of programming platforms

Paul Boughton
A rugged industrial HMI with touch-screen display is now available, which is certified for use in Class I, Division 2 hazardous gas or dust environments, in operating temperatures from as low as -30˚C up to 70˚C. The HMI also comes with a choice of programming platforms and offers a variety of interfacing options.

The QTERM-A7 and QTERM-A12 HMIs from Beijer Electronics, available in the UK from M.A.C Solutions, are high specification, industrial-grade HMI terminals, which are suitable for use in a wide range of industrial and commercial applications, including food processing, bakeries, chemicals, petrochemicals, mining and quarrying, metalworking, and pharmaceuticals.

The QTERM-A7 features a 7-inch vivid 800 x 480 WVGA, LED backlit colour graphics TFT-LCD display. User input is via the unit’s resistive, touch-screen display. The unit is also supplied with an integrated 10/100Base-T Ethernet interface, two USB 2.0 full speed host ports and two serial ports. The QTERM-A7 is sealed to IP66 and when mounted correctly, the unit also meets NEMA-4X specifications for wash downs, icing and salt spray.

The QTERM-A12 HMI offers all the functionality and features of the QTERM-A7, but has a larger, 12.1-inch, 800 x 600 SVGA display.

The user also has a choice of configuration software, including Beijer’s iX software for automation control, QlarityÒ 3 object-based programming, or Windows Embedded CE 6.0 development. iX Developer, which is common to ALL Beijer HMIs, includes vector-based graphics, solid HMI functionality, open architecture and OPC connectivity.

Other features provided on the QTERM HMIs include built-in protection from power transients and spikes, reverse voltage and overvoltage; 4GB of flash memory storage; real time clock; programmable speaker; .wav audio decoder; and a customisable front bezel logo.
