Allen Bradley 1734-IK — Detailed Technical Overview (POINT I/O Thermocouple / Millivolt Input Module)
1. Product Overview
The Allen Bradley 1734-IK is a 2-channel thermocouple and millivolt analog input module designed for temperature and low-level signal measurement in distributed automation systems. It belongs to a modular I/O platform that allows field-level signal acquisition close to sensors, improving accuracy and reducing wiring complexity.
This module is specifically designed to accept inputs from thermocouples (such as Type J, K, T, E, R, S, N) and millivolt signals, making it suitable for precise temperature monitoring and process control. It includes built-in cold junction compensation (CJC) to ensure accurate thermocouple readings.
The module connects to a POINT I/O system through a backplane and communicates with a controller via a network adapter. Its compact size and high measurement accuracy make it ideal for temperature-sensitive industrial applications.
