AB 1794-IT8
Allen-Bradley 1794-IT8 is an analog input module in the Rockwell Automation Flex I/O system. It is specifically designed to capture analog signals at the thermocouple and millivolt levels and convert these signals into digital signals that can be recognized by the PLC. The module is widely used in industrial process control to measure physical quantities such as temperature and pressure.
Main function
Thermocouple/millivolt signal acquisition: Multiple types of thermocouple and millivolt signals can be acquired.
Signal conversion: the analog signal is converted to digital signal, which is convenient for PLC processing.
Cold end compensation: Provides cold end compensation function to improve measurement accuracy.
Linearization: The thermocouple signal is linearized to facilitate the user to read the temperature value directly.
