Allen-Bradley 1746-NT8: 8-Channel Thermocouple Module for Precision Industrial Temperature Sensing
Allen‑Bradley 1746‑NT8 Product Introduction
The Allen‑Bradley 1746‑NT8 is an 8‑channel thermocouple/millivolt (mV) analog input module belonging to the Allen‑Bradley SLC 500 series, engineered by Rockwell Automation. It is tailored for high‑precision temperature and low‑voltage signal measurement in industrial automation scenarios, facilitating seamless integration with SLC 500 chassis and processors to deliver reliable and accurate data acquisition.
Core Features of 1746‑NT8
- Multi‑channel & Versatile Input: Equipped with 8 backplane‑isolated channels, it supports a wide range of thermocouple types (J, K, T, E, S, R, B, N) and mV input ranges (±50 mV, ±100 mV), accommodating diverse industrial sensing needs.
- High Precision & Stability: Boasts 16‑bit resolution for precise signal conversion, and features integrated cold junction compensation (CJC) with two sensors offering ±1.72°C accuracy, ensuring consistent and accurate temperature readings.
- Flexible Performance Tuning: Offers selectable input filter frequencies (10 Hz, 50 Hz, 60 Hz, 250 Hz) with corresponding cut‑off frequencies (2.6 Hz, 13.1 Hz, 15.72 Hz, 65.5 Hz) to minimize electrical noise, and update times ranging from 356 ms to 4.05 seconds to meet different application response requirements.
- Intelligent Maintenance & Monitoring: Automatically calibrates at power‑up and approximately every two minutes thereafter. It is equipped with 9 green LEDs for real‑time channel and module status monitoring, simplifying troubleshooting.
- Robust Protection & Isolation: Provides input over‑voltage protection (±30V DC continuous, 600W pulsed for 1 ms) and backplane isolation, along with excellent common and normal mode rejection (both >100 dB at 50/60 Hz) for stable operation in harsh industrial environments.
