• In production or process control applications where panel space is limited (3.5″ display)
• In combination with PLCs (e.g., production line controllers) using RS-232C or RS-422/485 communication — enables data exchange with control units
• In installations requiring a well-protected front panel (IP65), such as industrial environments with exposure to dust or splashing liquids
• In retrofit or modernization projects, where replacing older panels with a modern touch-screen interface is beneficial
