The Mitsubishi AJ65BT68TD is designed as a thermocouple temperature input module suitable for precision temperature monitoring. It can accept sensor inputs ranging from -200 °C to 1700 °C. The detected temperature is presented as a 16-bit signed binary output, allowing for precise measurement representation scaled to provide one decimal place accuracy.
With a cold junction compensation accuracy of ± 1.0 °C, the module ensures reliable readings across different operating conditions. The maximum resolution varies among thermocouple types: B, R, and S thermocouples achieve a resolution of 0.3 °C, while K, E, J, and T thermocouples have a resolution of 0.1 °C. Each channel has a sampling time of 45 ms plus an additional 2 ms per channel, providing timely data collection.
The AJ65BT68TD module is equipped with eight analog input channels along with an extra Pt100 channel for diverse input capabilities. The input to transmission insulation method utilizes transformer insulation, enhancing the system's safety and reliability.
This module functions as a CC-Link remote device station, occupying four stations: each RX/RY can handle 128 points, and RWw/RWr can manage 16 points. For external power, it operates optimally with 24V DC power supply, accommodating an input range of 18 to 30V DC. The operational ambient temperature for this device ranges from 0 to 55 °C, making it suitable for various industrial applications. Weighing in at 0.40 kg (0.88 lbs), this module is compact and easy to integrate into existing systems.
