At its core, the VS-043QE features a 4.3-inch TFT display with 480 x 272 resolution and a 64K (24-bit) colour palette, delivering clear graphics, legible text and vivid status indications. With 400 cd/m2 brightness, the screen remains readable in typical industrial lighting, while the 4-wire resistive touch panel provides accurate, glove-friendly operation on the factory floor. The interface supports rich visual elements - trends, alarms, recipes, indicators and animated graphics - enabling operators to monitor and control machinery quickly and confidently.

Performance is driven by a Cortex-A7 1 GHz dual-core CPU paired with 128 MB of DDR3 memory and 128 MB of flash storage, providing ample headroom for responsive screen switching, smooth animation and complex project files. This processing capability ensures that even graphically detailed applications run fluidly, reducing operator wait times and improving the overall machine experience. The generous memory also accommodates substantial project content, including multiple screens, logos, multilingual text and historical data buffers.

• Connectivity is a key strength of the VS-043QE.
• It provides one USB Host and one USB Client port for data transfer, project download and peripheral connection, along with serial interfaces comprising COM1 (RS232) and COM2 (RS485/422).
• These ports allow the panel to communicate with a broad ecosystem of PLCs, drives, servos, instruments and other field devices using common industrial protocols, making it easy to integrate into existing control architectures.
• While this model does not include built-in Ethernet, its serial flexibility covers the majority of compact-machine communication needs, and INVT offers Ethernet-equipped variants where networking is required.

Built for industrial reliability, the VS-043QE carries an IP65-rated front panel that resists dust and water from the operator side, supporting installation in workshops, packaging lines and other challenging environments. It operates across a -20 C to +55 C temperature range and runs on a 12-24 VDC supply consuming just 3 W, simplifying power provision and panel design. With compact dimensions of 150 x 93 x 39 mm and a light 0.2 kg weight, it fits neatly into cabinet cut-outs and small enclosures without adding bulk.

Engineering and maintenance are streamlined through INVT HMITOOL software, which provides a comprehensive environment for screen design, communication setup, alarms, recipes, data logging and multilingual projects. The toolchain helps integrators develop and commission applications quickly, while USB-based project transfer simplifies updates and servicing in the field. Combined with the panel's dependable hardware, this lowers total cost of ownership and shortens time to deployment.

The VS-043QE is used across a wide spectrum of industries, including general manufacturing, printing and packaging, textile machinery, woodworking, medical equipment, food processing and agricultural automation. In each, it serves as an affordable yet capable operator window - displaying process status, enabling parameter adjustment, presenting alarms and guiding operators through machine sequences. Its blend of clear graphics, solid processing, flexible serial connectivity and rugged construction makes it a versatile choice for OEMs seeking to enhance machine usability without inflating cost.
