BEIJER E300-02750C｜HMI Panel｜
The E300 series is Beijer’s compact HMI line for small- and medium-sized projects with higher performance requirements.
The “02750C” configuration balances cost-effectiveness and functional scalability, making it suitable for:
PLC control system operation for small and medium PLCs (Siemens S7-1200, Mitsubishi FX5U, Schneider M241, etc.).
Centralized monitoring of multi-device linkage scenarios such as assembly lines, packaging lines, or HVAC systems.
Single-machine devices requiring richer communication interfaces (e.g. injection molding machines, CNC machine tools, temperature-control units) where PLCs and sensors must be connected simultaneously.
