The Mitsubishi AJ65BT68TDC is a dedicated temperature input module tailored for thermocouples. It offers a comprehensive measurement range between -200°C and 1700°C. The output is in the form of a 16-bit signed binary scale, accommodating values from -2000 to 17000, precisely calculated with one decimal place scaled by ten. This module is capable of achieving high levels of accuracy with a maximum resolution of 0.1°C for K, E, J, and T type thermocouples, and 0.3°C for B, R, and S types.
Data processing is efficient, with each channel requiring 45 milliseconds for conversion, plus an extra 2 milliseconds for further processing. It contains a total of eight analog input channels and one channel for Pt100 connections, making it versatile for various applications. The AJ65BT68TDC module occupies four station slots in a CC-Link configuration, supporting 128 points for RX/RY and 16 points for RWw/RWr.
To maintain high performance, it receives a DC power supply within a specified range of 18 to 30 volts, with a typical consumption of 0.081 A. The module boasts transformer-based insulation between thermocouple inputs and the CC-Link interface while ensuring cold junction compensation precision is ±1.0°C. The maximum input voltage the module can handle is ±5 volts. Designed for seamless integration in automation systems, this module defines reliability in temperature measurement applications.
