The 1746-NR4 is an Allen-Bradley SLC 500 series RTD (Resistance Temperature Detector) input module used for precision temperature measurement in industrial process control applications. This module interfaces directly with RTD sensors — including Pt100, Pt1000, Ni120, and other industry-standard RTD types — converting their resistance-based temperature signals into digital values for the SLC 500 processor. RTD inputs provide superior measurement accuracy compared to thermocouple inputs, making the 1746-NR4 the preferred choice for applications requiring precise temperature monitoring in manufacturing, process, and utility environments. Powergenics offers professional repair services for Allen-Bradley SLC 500 specialty I/O modules including the 1746-NR4, restoring accurate RTD temperature measurement capability.
