Mitsubishi Electric FX3U-4AD-TC-ADP

Product information "Mitsubishi Electric FX3U-4AD-TC-ADP"

Mitsubishi Electric FX3U-4AD-TC-ADP Thermocouple Input Adapter

The FX3U-4AD-TC-ADP is a specialized analog expansion adapter for the MELSEC-F (FX3U, FX3UC, FX3G, and FX3GE) series PLCs. Designed for precise temperature monitoring, this module allows for the direct connection of up to four independent thermocouple sensors without the need for external signal transmitters. By connecting directly to the left-side communication bus of the main PLC unit, it seamlessly maps temperature data into internal special registers without consuming standard I/O points.

Technical Specifications

  • Analog Input Channels: 4 independent channels for thermocouple temperature sensors.
  • Supported Sensor Types:
    • Type K: -100°C to 1200°C (Resolution: 0.4°C)
    • Type J: -100°C to 600°C (Resolution: 0.3°C)
  • Conversion Speed: 15 ms per channel (data is automatically updated in the PLC special data registers).
  • I/O Point Consumption: 0 points (does not subtract from the main unit's maximum I/O count).
  • Isolation: Photocoupler isolation between the analog input area and the PLC. (Note: Channels are not isolated from each other).
  • Cold Junction Compensation: Integrated internally for high-accuracy temperature readings.
  • Installation: Mounts to the left side of the base unit. Note: An expansion board (e.g., FX3U-CNV-BD) is required when connecting to an FX3U or FX3G main unit.

Ideal Applications

Industrial ovens and furnaces, plastic extrusion molding machines, HVAC control systems, and localized heat treatment processes requiring multi-zone temperature regulation.
