HMIs
A Human-Machine Interface or HMI is a critical component in industrial automation systems, providing an intuitive graphical user interface to enable operators to interact with the machinery and control processes. An HMI facilitates real-time monitoring, control, and visualization of data, allowing operators to make informed decisions quickly. These devices are available in various forms, including touchscreens, displays, and mobile devices. These devices offer a wide range of features, including data logging, alarms, and remote access. At SIGMA Surplus, we carry several Allen Bradley HMI models, Siemens HMI models, Automation Direct HMI models, and many more from leading OEMs.
