Q68RD3-G Mitsubishi Universal model Redundant Power Supply Module

Q68RD3-G Description

The Mitsubishi Q68RD3-G is an 8-channel isolated RTD (Resistance Temperature Detector) input module designed for the MELSEC-Q series PLC system. It enables high-precision temperature measurement and is compatible with RTD sensors such as Pt100, JPt100, and Ni100. This module is engineered for industrial automation applications where reliable temperature monitoring is critical, such as in process control, HVAC systems, and manufacturing equipment. It features channel-to-channel isolation to minimize interference and supports fast, accurate data conversion for real-time control .

Q68RD3-G Key Features

•
Multi-Channel Input: Supports 8 independent RTD input channels, allowing simultaneous temperature monitoring from multiple points .
•
High Compatibility: Works with widely used RTD types, including Pt100, JPt100, and Ni100, covering a broad temperature range .
•
Isolated Design: Each channel is electrically isolated to prevent cross-talk and ensure signal integrity in noisy industrial environments .
•
High Resolution: Offers precise temperature measurement with a resolution of 0.1°C, ideal for applications requiring fine accuracy .
•
Diagnostic Capabilities: Includes wire break detection for each channel, facilitating quick troubleshooting and maintenance .
•
Fast Conversion Speed: Converts all 8 channels within 320 ms, suitable for real-time control systems.
•
Easy Integration: Designed for seamless installation into MELSEC-Q series PLC racks, with simple configuration via PLC programming tools
•
Robust Construction: Housed in an aluminum alloy casing, providing durability and protection against harsh conditions .

Q68RD3-G Material & Applications

•
Material: The module is constructed with an aluminum alloy housing, ensuring lightweight yet robust protection against dust, vibration, and electromagnetic interference commonly found in industrial settings
•
Primary Applications:
- •
  Industrial Process Control: Monitoring temperature in chemical, pharmaceutical, or food processing industries.
- •
  HVAC Systems: Integrating into building automation for energy management and climate control.
- •
  Manufacturing Automation: Used in machinery and production lines to prevent overheating and ensure operational safety.
- •
  Data Acquisition Systems: Coupled with SCADA or PLCs for logging and analyzing temperature trends over time .
