Q62DA Mitsubishi Universal model Redundant Power Supply Module
Q62DA Description
The MITSUBISHI Q62DA is a high-precision, 2-channel digital-to-analog (D/A) converter module belonging to the MELSEC-Q Series PLC I/O lineup. This module converts 16-bit digital signals from the Q Series PLC CPU into precise analog voltage or current outputs, enabling seamless control of analog field devices such as variable frequency drives, temperature controllers, proportional valves, and recorders. Designed for industrial process control and precision automation applications, it offers flexible output configuration, high accuracy, and fast conversion speed. The Q62DA features multi-resolution modes and user-definable output ranges, making it highly adaptable to diverse control requirements. It mounts directly onto the Q Series backplane, integrating seamlessly into the distributed control system.
