MELDAS CNC PLC

The MELDAS CNC PLC series is a family of programmable logic control boards and modules manufactured by Mitsubishi for use in CNC machine tool systems. These products integrate CNC and PLC functionality, coordinating machine motion control with the sequential logic that manages auxiliary equipment such as tool changers, coolant systems, and safety interlocks.

The series spans a range of board types found in Mitsubishi MELDAS control systems, commonly used on CNC mills, lathes, and machining centers.

Product Types in This Series

• CPU and control boards — main controllers that execute machine control programs and coordinate I/O operations.
• Digital I/O and input boards — interface field devices such as sensors, switches, limit devices, and relays with the CNC controller.
• Graphics and CRT controller boards — drive color CRT operator displays for machine status monitoring, program editing, and operator input.
• Memory boards and complete numerical control systems that combine CNC and PLC functions.

These boards are typically found in older MELDAS CNC installations where they manage real-time motion control, discrete I/O, and operator interface functions for automated manufacturing equipment.
