AB 1746-NT8

Description

AB 1746-NT8 is a SLC 500 series thermocouple/voltage analog input module produced by Allen-Bradley(AB).The following is a detailed introduction to the module:

I.Product Overview

The AB 1746-NT8 module is an eight-channel module mounted on a base that receives thermocouple/voltage signals and converts them into digital signals for retrieval by any SLC 500 processor.This module is specifically designed for thermocouple/millivolt inputs and is compatible with SLC 500 processors such as SLC 5/01,5/02,5/03,5/04,and 5/05.It can be used in SLC fixed or modular hardware categories.

II.Main Features

Multi-channel design:AB 1746-NT8 has 8 input channels and can receive multiple thermocouple or voltage signals simultaneously.

Strong compatibility:The module is compatible with thermocouple sensors such as J,K,T,E,S,R,B and N,as well as mV inputs such as+/-50 mV and+/-100 mV.

High precision:Adopts high-precision conversion technology to ensure accurate conversion and transmission of signals.

Automatic calibration:The module automatically calibrates approximately every 2 minutes after power-on to ensure measurement accuracy.

Overvoltage protection:Provides input overvoltage protection of+/-30V DC and 600W pulse 1ms to protect the module from damage.

Circuit isolation:Provides 12.5V DC circuit isolation between input and chassis ground and between input and backplane to improve system safety and stability.
