The Allen-Bradley 1746-NT8 is an advanced Thermocouple/mV Analog Input Module tailored for the SLC 500 series. Designed to handle up to eight input channels, this module efficiently receives analog signals from thermocouples or millivolt inputs and converts them into digital data using Delta-Sigma modulation. It boasts an impressive signal integrity, with common mode and normal mode rejection frequencies exceeding 100dB at 50-60Hz, while offering robust input overvoltage protection and 12.5V circuit isolation. The 1746-NT8 features self-calibration, selectable filter frequencies, and input type flexibility, making it compatible with a range of SLC processors. Its design includes sophisticated error detection and nine LED indicators for channel and module status. Equipped with a 1746-RT34 removable terminal block, it includes cold-junction compensation sensors and supports various data formats conducive to accurate temperature monitoring and control, ensuring seamless integration within both fixed and modular SLC 500 hardware configurations.
