Analog-to-Digital Converter Module – MITSUBISHI ADC-04D
The ADC-04D is an analog-to-digital converter module (“Analog-to-Digital Converter Module”) manufactured by Mitsubishi Electric, designed for CNC and industrial automation control systems of the MELDAS series and compatible architectures. The unit acquires analog voltage or current signals from sensors, transducers, or potentiometers and converts them into digital values that can be processed by the CNC controller. The designation ADC-04D identifies a converter with 4 independent analog input channels; the trailing letter “D” denotes the hardware variant or revision. Depending on the host system architecture, it may be installed as a plug-in board on a backplane or as a standalone module.
The A/D converter module performs an essential role in bridging the physical world of analog signals and the digital logic of the numerical controller: without it the CNC cannot read continuous quantities such as positions, temperatures, pressures, or speeds. A failure in the converter manifests as incorrect or missing feedback channel readings, feedback alarms, and immediate machine stops, making any machining cycle impossible.
Mitsubishi Electric is one of Japan’s largest multinational electronics and industrial automation conglomerates, with over a century of history. Its FA (Factory Automation) division produces the world-class MELDAS / M700 / M800 CNC controller series, MELSERVO servo drives, and MELSEC PLCs. Products in the ADC-04D family belong to earlier-generation control architectures and are to be considered legacy / discontinued: availability is limited to the used market and specialist repair services.
