The Allen-Bradley 1746-INT4 SLC 500 Thermocouple/mV Isolated Input Module is expertly designed for seamless integration with SLC 500 processors, offering robust digital conversion of thermocouple and analog millivolt data. This module is equipped with four individually isolated input channels, accommodating multiple thermocouple types such as B, C, D, E, J, K, N, R, S, and T, as well as mV signals ranging from -100 to 100 mV DC. Ensuring precise data capture, it features a low pass digital filter with high noise rejection, cold junction compensation, and selectable temperature and millivolt scales, while the isolation is rated at 1000V transient. With operational conditions from 0-60 °C and essential certifications including CE, CSA, and UL, the 1746-INT4 is built for reliable performance in demanding industrial environments.
