HMIs (Human Machine Interfaces)

HMIs for Industrial Automation | MRO Electric

Industrial HMIs provide real-time monitoring, alarm management, and parameter adjustment for automated systems. Models like the PanelView 550 or SIMATIC HMI Comfort Panel support Ethernet/IP, Modbus TCP, ProfiNet, and other industrial protocols, ensuring integration with PLCs and CNC machines. Designed for touchscreen or keypad input, these HMIs withstand harsh industrial environments and offer transparent displays, fast response, and long service life, making them essential for packaging lines, robotic systems, CNC machinery, and process automation.
