Overview: Solving Industrial Measurement Challenges
The Mitsubishi A1S62RD3 analog input module addresses a critical industrial automation challenge: accurate process variable measurement and conversion. In manufacturing environments where temperature, pressure, flow, and level monitoring are essential, this module serves as the bridge between physical sensors and digital PLC control systems. Without reliable analog input capabilities, process control becomes guesswork, leading to quality issues, energy waste, and production downtime.
This 2-channel analog input module from Mitsubishi's A-Series family provides high-precision signal conversion with robust industrial-grade construction. The included 1-year warranty ensures reliable performance in demanding industrial environments, making it a trusted component for Industrial Automation systems.

The A1S62RD3's 16-bit resolution provides exceptional measurement granularity, allowing for precise monitoring of process variables. The channel-to-channel isolation ensures that signals from different sensors don't interfere with each other, a critical feature in complex Control Systems where multiple measurements occur simultaneously.
Buying Considerations: Selection Guide
When selecting the Mitsubishi A1S62RD3 module for your automation system, consider these critical factors:
- System Compatibility: Verify compatibility with your existing Mitsubishi A-Series PLC Base Units. The module requires an A1S35B or A1S38B base unit for proper installation.
- Signal Type Requirements: Determine if your sensors output 0-10V DC or 4-20mA signals. The A1S62RD3 supports both, but proper configuration is essential.
- Channel Count: With only 2 channels, ensure this meets your application needs. For systems requiring more inputs, consider multi-channel alternatives or additional modules.
- Environmental Conditions: The 0-55°C operating range suits most industrial environments, but verify your specific temperature and humidity conditions.
- Programming Requirements: Mitsubishi's GX Works software is required for configuration and programming. Ensure your team has the necessary software and expertise.
- Warranty Coverage: The 1-year warranty provides peace of mind, but consider extended warranty options for critical applications.
- Spare Parts Strategy: For mission-critical systems, consider purchasing backup modules to minimize downtime during failures.
Frequently Asked Questions
Q1: Can the A1S62RD3 module handle thermocouple or RTD inputs directly?
A: No, the A1S62RD3 is designed for standard voltage (0-10V DC) and current (4-20mA) signals. For temperature sensors like thermocouples or RTDs, you would need a dedicated temperature input module or external signal conditioners that convert temperature signals to the compatible voltage/current ranges.
Q2: How do I configure the input range and scaling for different sensors?
A: Configuration is done through Mitsubishi's GX Works programming software. You'll set parameters for each channel including input type (voltage or current), scaling factors, and alarm limits. The module supports both linear and custom scaling to match your specific sensor characteristics.
Q3: What maintenance is required for the A1S62RD3 module?
A: The module is designed for minimal maintenance. Regular checks should include verifying proper connections, monitoring for environmental contamination, and periodic calibration verification. The solid-state design means no moving parts to wear out, but ensure proper ventilation and protection from excessive dust or moisture in your Industrial Control Cabinets.
