HMI Displays

HMI means 'human-machine interface' and these interfaces are intended to streamline the use of industrial machinery by connecting a person to a machine, system or device, such as PLC's, RTU's and IED's. Their purpose is to provide insight into mechanical performance and progress. Integrated HMI solutions remove the need for physical wires, switches, dials and controls and replaces them with software. This allow users more autonomy over monitoring and automation, allowing them perform functions such as starting and stopping cycles, adjusting set points and other processes when interacting with a control process.

HMI displays are available in a range of different screen sizes, resolutions and colours. They can be configured to support both landscape and portrait devices including wide screen, multitouch and smart panel designs depending on their intended end use. When choosing the right HMI device, certain parameters should be considered, including processor speed, memory, port and processor type.

For more information see our industrial displays guide.
