Product Details Introduction

Introduction to 1746-NR4 Resistance Analog Input Module

1746-NR4 is a dedicated 4-channel resistor/RTD analog input module for the Rockwell SLC 500 series, mainly used for temperature and resistance signal acquisition. The following is a detailed introduction:

Belonging to SLC 500 series 4-channel resistor and RTD analog input module

Supports various RTD sensors such as Pt100, Pt1000, Ni120, Cu10, etc

Can directly measure resistance signals of 150 Ω, 500 Ω, 1000 Ω, and 3000 Ω

Supports 2-wire, 3-wire, and 4-wire wiring methods, effectively reducing line errors

Built in excitation current source and high-precision A/D conversion circuit

Can output signals in Celsius, Fahrenheit, or resistance values

Equipped with digital filtering function to enhance signal stability

Support fault detection and self calibration for wire breakage, short circuit, and over range faults

Electrical isolation between input and backplane, strong anti-interference ability

Equipped with module and channel status LED indicator lights

Occupying a single slot in the SLC 500 rack, easy to install

Adopting detachable terminal blocks for convenient on-site wiring and maintenance

Powered by the backplane power supply, no additional external power is required

Widely used in industrial temperature monitoring, potentiometer signal acquisition and other scenarios

This model has been discontinued, and the market mainly consists of second-hand and refurbished spare parts

In summary, 1746-NR4 is a high-precision analog input module specifically designed for resistance and RTD temperature measurement in the SLC 500 system, suitable for various industrial equipment that requires precise temperature acquisition.
