Mitsubishi Electric Q68DAIN MELSEC Q Series Digital-Analog Converter Module

Description

Designed for integration with MELSEC Q Series PLC systems, the Q68DAIN digital-analog converter module provides high-precision digital-to-analog current conversion across eight independent channels. This module processes 16-bit signed binary digital values to drive precise current signals for field instruments, actuators, and control valves. High-speed signal processing combined with robust channel protection ensures reliable operation in demanding industrial control environments.

Features

• Eight independent analog output channels for multi-device control.
• High-speed conversion rate of 80 us per channel.
• 16-bit signed binary digital input resolution.
• Built-in output short-circuit protection to prevent hardware damage.
• Standard 18-point removable terminal block connection interface.

Applications

• Modulating control valves and positioners in process industries.
• Variable speed drive (VSD) speed reference control.
• Water and wastewater treatment automation.
• Chemical processing and material handling systems.

Installation Guidelines

• Ensure the PLC base unit power supply is completely switched off before mounting or removing the module.
• Securely tighten the module mounting screws and terminal block screws to the specified torque.
• Use shielded twisted-pair cables for all analog output lines to minimize high-frequency electromagnetic interference.
• Maintain physical separation between signal cables and high-voltage power lines or motor drive cables.
• Ground the shield of the output cables at a single point near the control cabinet entry.
