The US company has launched the HFX controller and VFX display families. The control units are IP67- and IP69K-rated. Their die-cast aluminum housing is rugged enough to withstand temperatures from -40 °C to +105 °C. The products based on the H72546 micro-controller provide multiple inputs and outputs, including three CAN ports. The CAN interfaces support CANopen or J1939 protocols. They provide a 3,75-MiB flash memory and an additional 32-KiB MRAM as well as SRAM (256 KiB) and EEPROM (128 KiB).

The product line also includes two displays: 4,3 and 7 inches. Like the controllers, the human machine interfaces comes in IP67-rated enclosures. They are readable in direct sunlight. With a backlight and an optically-bonded liquid crystal display (LCD) screen, the displays are protected against fog and dust contamination.

Eaton has also released the Pro-FX configuration software, which is based on Codesys version 3.5, which complies with 61131-3. The software supports six programming languages, including graphical and textual, as well as a set of function block libraries. The libraries contain pre-configured software objects to help customers developing their applications. The software includes integrated CANopen and J1939 protocol stacks. The software suite also contains graphic capabilities that can be used to create individual human machine interfaces.
