Human-machine interface (HMI) products incorporate electronics essential for controlling and signaling various types of automation equipment in industrial environments. These products range from simple designs with basic LED indicator screens to more sophisticated systems featuring touchscreens and additional functionalities. It’s crucial for HMI systems to possess durability to withstand challenging conditions, including resistance to dust, moisture, extreme temperatures, water, and, in some instances, exposure to hazardous chemicals. But what types are available? 
- Data Handler: Designed for applications demanding continuous system feedback or detailed production reports, the data handler HMI is ideal. It encompasses functions such as data trending, alarm management, data logging, and recipe management, requiring sufficient size for visual representations, graphs, and production summaries.
- Pushbutton Replacer: This HMI optimizes manufacturing processes by consolidating every button function into one accessible location.
- Overseer: Beneficial for applications involving Manufacturing Execution Systems (MES) or Supervisory Control and Data Acquisition (SCADA), the overseer HMI typically requires multiple Ethernet ports and is compatible with Windows operating systems.
