Veichi VI20 — HMI Operator Panel Series
The Veichi VI20 series is a range of graphic touchscreen operator panels (HMI) designed for visualization and control of industrial processes. VI20 panels are built on ARM Cortex-A8 processors running at up to 1 GHz, feature LED backlighting, and provide stable operation with DC 24V power supply (9–28V range). The series covers screen sizes from 4.3 to 15.6 inches, allowing selection of the optimal display for each specific automation application.
VI20 Series Technical Specifications
All VI20 models are graphic TFT panels with resistive touchscreen. Base models (suffix -F) support the Modbus RTU protocol through serial RS232/RS485/RS422 ports. Extended models (suffix -FE) additionally feature an Ethernet 10/100 Mbps port with Modbus TCP support, simplifying integration into networked SCADA systems. The flagship VI20-156S-FE is equipped with dual Ethernet ports, a Micro SD slot, and a metal enclosure rated IP65.
Key common specifications across the series:
- Power supply: DC 24V (range 9–28V; 18–28V for the 15.6" model)
- Interfaces: RS232, RS485, RS422 in various combinations
- Protocols: Modbus RTU (base), Modbus RTU/TCP (with Ethernet)
- USB: Type-C OTG (4.3") or USB Slave/Host 2.0
- Processors: ARM 720 MHz (4.3"), Cortex-A8 600 MHz (7–10.1"), Cortex-A8 1 GHz (15.6")

VI20 Panel Applications
VI20 series panels are used to build human-machine interfaces in industrial automation systems: conveyor lines, pumping stations, HVAC systems, packaging machines, and CNC equipment. With Modbus RTU and TCP support, VI20 panels integrate seamlessly with variable frequency drives, PLCs, and other Veichi automation devices — including AC70, AC310, and SD700 series inverters.
The compact 4.3" model is suitable for small installations and control panels; 7-inch panels are a universal choice for most applications; 10.1" and 15.6" models are used for complex visualization systems requiring multiple screens and trend graphs.
