NORVI RPI-HMI is an industrial controller with a 7-inch touchscreen screen display powered by a Raspberry Pi CM4 and equipped with a range of interfaces including a gigabit Ethernet RJ45 port, a few USB ports, and several terminal blocks for RS485 (Modbus), digital and analog input, transistor outputs, and 24V DC power input.
The new Raspberry Pi CM4-based HMI announcement follows the NORVI ESP32-HMI controller that was launched last December with an ESP32-S3 wireless microcontroller and a 5-inch LCD display with resistive touch. The NORVI RPI-HMI builds on that with a much faster Arm processor, a larger display with a capacitive touchscreen, gigabit Ethernet, and a wider range of I/Os that makes it suitable for various industrial HMI and PLC applications.
NORVI RPI-HMI Industrial Controller specifications:
The NORVI RPI-HMI runs Raspberry Pi OS with all necessary drivers and can be programmed with Python, Node-Red visual flow-based programming tool, or CODESYS automation software. Hardware documentation and getting started guides can be found on the documentation website. Two different product parts are listed “SC-PC-AX8-TO7” and “SC-PC-AV8-TO7” but I could not find any obvious differences between the two models. Both take various Raspberry Pi CM4 and CM4 Lite variants with 2GB or 4GB RAM and up to 32GB flash.
Typical applications for the NORVI RPI-HMI include PLCs with a touch panel, HMIs with Ethernet and RS485 interfaces, Raspberry Pi-based HMIs or PLCs, local IoT servers, and industrial gateways. NORVI is not the only company offering HMI solutions based on the CM4, and we previously covered several models from EDATEC as well as Seeed Studio’s reTerminal DM which offer options with different I/Os and features.
NORVI sells its Raspberypi CM4 industrial HMI solution for $287.05 to $326.70 depending on the selected CM4 module. Additional information may also be found on the product page.

The prices on their website are from $657.34 to $748.14. Way too expensive!
The difference between M and V variants is just the voltage or current analogue in, see datasheets.
One thing that worries me a bit is there is nowhere any mention of overload or short circuit protection of any of the I/Os
Nevertheless might bug my boss to order one for eval.
