The IDEC HG2J Series 7-in. touchscreen HMIwith projected capacitive touch panel (PCAP) technology saves space, improves performance, is wear resistant, and provides a long life. The self-capacitance technology can prevent accidental input due to water droplets. The PCAP glass is more resistant to scratches, won’t turn yellow in the sun, and has a higher tolerance for dirt deposits, and for contact with cleaning or washdown chemicals. Fewer layers and better light transmission ratings mean less backlight power is needed and provides an industry-leading 500 cd/m2 brightness level and 50,000-hour backlight life.
With a TFT LCD display resolution of 800x480 pixels, the HMI is conveniently sized for applications both small and large, and it provides smooth font rendering within its large high-visibility display area. This PCAP display does not require the large bezels of standard IR displays, allowing the bezel to be slimmer and sleeker in appearance for a small installation footprint, and the overall HMI depth is just 30 mm, substantially less than the 40 mm or more depth required by competing products.
Operation with an input voltage of 12-24 VDC makes the HMI suitable for a wide variety of industrial applications. The HMI is rated for operation in an exceptionally wide temperature range of -20 °C to 60 °C, and it carries IP66/67, UL, and CE ratings, with a Class I Div 2 hazardous location rating.
The HMI features a full complement of connectivity options, including two USB A ports, serial connectivity (RS485/422 and RS232C), and an Ethernet port. Push-in wiring connectors are used for power and serial connections, providing easy installation and service. The USB ports enable connectivity with Linux-compatible accessories, such as Wi-Fi and Bluetooth dongles, speakers, and barcode readers.
A single reset button is used for rebooting the unit, and a multifunction front LED light provides status information for the hardware, boot mode, and OS operating mode. Maintenance is simplified, because the HMI requires no batteries, it uses MRAM to maintain data stored in internal data registers in the absence of power, and it features a hypercapacitor to maintain clock operation for up to two weeks without line power.
The HMI supports over 100 serial and Ethernet industrial communication protocols, including Modbus, providing connectivity with most PLC makes and models and making it ideal for industrial internet of things (IIoT) applications. The HMI supports simultaneous use of up to four protocols, and the User Communication Protocol function allows users to develop their own protocols for specialty serial or Ethernet devices. A built-in web server provides remote access functionality for PCs and mobile devices just as if the user were in front of the HMI itself—improving operation, troubleshooting, and maintenance—while the FTP client/server protocol can be used for transferring configurations and data between local memory and external systems. Email functionality provides up to 255 templates so alarm logs, data values, screenshots, and more can be transmitted to multiple recipients securely using SMTPS and SSL. The HMI also supports Twitter for notifying users of system status.
The HMI OS provides 24Mb of user application memory and more address space than prior models. Download time is nine times faster than prior models, and it supports a wide variety of external devices and printers.
