Operator Panel and HMI
Operator Panels, also known as human machine interfaces (HMI), permit interaction between human operators and industrial control systems such as programmable logic controllers (PLC). Products range from text panels with keypads to highly customizable graphical displays with touch screens. The interface is designed to provide operators with the ability to monitor critical process variables and input commands to query or modify the behavior of the machinery under control. Industrial operator panels are ruggedized for use in harsh environments.
