The AJ65SBT2B64TD module from Mitsubishi is specialized for analog thermocouple applications. It consists of four input channels dedicated to thermocouples, along with two additional channels designated for Pt100 temperature sensors. This unit is compatible with various thermocouple types, including B, R, S, K, E, J, T, and N, facilitating a wide array of temperature measurement capabilities. The module is designed to operate effectively in temperature readings from -270°C to 1820°C.
In practical usage, the temperature measured values can range from -2700 to 18200, allowing precise decimal place rounding for accurate assessments. For reliable cold junction compensation, this unit achieves an accuracy of ±1°C, essential for ensuring optimal measurement conditions. The maximum resolution is determined by the specific thermocouple type, with the B, R, S, and N thermocouples achieving a resolution of 0.3 °C, while K, E, J, and T types provide a finer resolution of 0.1 °C.
The AJ65SBT2B64TD also supports a conversion speed of 640 milliseconds across all four channels, with a sampling cycle that takes just 160 milliseconds for the same channels. It can handle an absolute maximum input of ±5V. Additionally, this module includes a built-in terminating resistor rated at 110 ohms to facilitate connections. Users can write data to the flash memory up to 10,000 times, which enhances the module's longevity and reliability in data storage. This remote device station utilizes CC-Link as its communication protocol and occupies a single station with RX/RY points as well as RWr/RWw points. Overall, the AJ65SBT2B64TD delivers thorough temperature monitoring and control options across various industrial settings.
