Description:

The Mitsubishi A1S68DAV is a digital-to-analog (D/A) converter module designed for the MELSEC-A series PLC platform, used to convert digital signals from the PLC into analog output signals for process control. Commonly installed in industrial automation systems and control panels, it enables precise control of devices such as drives, valves, and actuators. Maintenance teams and system integrators use this module for analog signal output, system expansion, and replacement of legacy analog modules.

Applications:

This Mitsubishi analog output module is used in industrial automation systems requiring accurate analog signal control. Typical applications include motor speed control, valve positioning, process automation systems, and manufacturing equipment where stable and precise analog output is critical to system performance and control accuracy.
