Allen-Bradley 1794-IJ2

Overview

The Allen-Bradley 1794-IJ2 is a 2-channel thermocouple/millivolt analog input module for the FLEX I/O system, ideal for temperature measurement and low-voltage signal acquisition. Operating at 24V DC, it is a non-isolated input module, designed for DIN rail mounting in distributed control systems. It provides a compact and modular solution for precise analog input in industrial environments.

Key Features

  • Input Channels: 2

  • Input Type: Thermocouple (J, K, T, E, R, S, B, N) and millivolt signals

  • Resolution: 16-bit

  • Operating Voltage: 24V DC nominal

  • Input Range: ±100 mV, thermocouple-specific ranges

  • Mounting: DIN rail via FLEX I/O base

  • Data Format: Scaled engineering units or raw data

  • Cold Junction Compensation: Via RTB with internal sensor

  • Diagnostics: Open-circuit detection and underrange/overrange flags

Technical Specifications

  • Catalog Number: 1794-IJ2

  • Update Rate: ~80 ms (per channel)

  • Accuracy: ±0.5°C (typical, depends on type)

  • Backplane Current (5V): 35 mA

  • Power Supply Current (24V): 25 mA

  • Operating Temperature: 0°C to +55°C

  • Storage Temp: -40°C to +85°C

  • Certifications: UL, cUL, CE, ATEX, RoHS

  • Compatible Terminal Bases: 1794-TB3, 1794-TB3S, 1794-TBN, etc.

Applications

  • Industrial temperature monitoring

  • Thermal process control

  • Packaging and food processing lines

  • Furnace and kiln control systems

  • Distributed analog I/O in PLC systems

Why Choose the 1794-IJ2

  • Versatile Sensing: Supports a wide range of thermocouple types and mV inputs

  • Compact Form Factor: Ideal for space-limited control cabinets

  • Cost-Effective: 2-channel configuration reduces I/O overhead

  • Integrated Diagnostics: Quickly detect open circuits and input faults

  • FLEX I/O Compatible: Easy integration into Rockwell Automation architectures
