Human Machine Interface display panels are visual systems that connects a person to a machine, system, or device. While the term can technically be applied to any screen that allows a user to interact with a device, human machine interface is most commonly used in the context of an industrial process. Similar to how you would interact with your air-conditioning system to check and control the temperature in your house, a plant-floor operator might use an HMI to check and control the temperature of an industrial water tank, or to see if a certain pump in the facility is currently running.
Human Machine Interfaces come in a variety of forms, from built-in screens on machines, to computer monitors, to tablets, but regardless of their format or which term you use to refer to them, their purpose is to provide insight into mechanical performance and progress. PLC Technologies South Africa supplies a wide range of HMI Screens from 4.3 inches to 15 inches.
