Product Description
The Allen-Bradley 1746-HT is a specialty module in the SLC 500 family, designed to serve as a servo termination panel and analog input interface for resistance-based devices, including RTDs. It provides four input channels capable of measuring temperature or resistance values with high precision, supporting common RTD types such as Pt100, Pt1000, Ni100, and Cu10.
The module features multiple voltage inputs (5 V DC, 15 V DC, 24 V DC) and is DIN-rail mountable, making it ideal for integrating with servo drives, fast I/O, and encoder systems. Although discontinued by the manufacturer, Radwell provides a 2-year warranty for continued maintenance and legacy system support.
This module is widely used in process industries, manufacturing, and energy systems, where accurate temperature monitoring and safe servo termination are essential.
