Exploring the Features and Versatility of Mitsubishi QTERM HMI Devices

What are Human Machine Interface devices?

Human-machine interface (HMI) devices are tools or interfaces that enable users to interact with electrical, mechanical, and electromechanical systems. They also allow the users to log data and monitor and control systems. HMI devices typically include user interfaces such as touchscreen, control panels, switches, indicators, and other I/O devices. They serve a variety of purposes, including troubleshooting in power distribution, industrial automation, process control, and machinery operation.
