Allen-Bradley 1756-IF8I | High-Precision Analog Input Module for ControlLogix Systems

Overview

The Allen-Bradley 1756-IF8I is an 8-channel isolated analog input module designed for ControlLogix chassis. Each input is individually isolated and configurable for voltage or current signals, offering precise measurement and robust noise immunity.

Key Features

  • 8 individually isolated analog input channels

  • Supports voltage (±10V, 0–10V, 0–5V) and current (0–20 mA) inputs

  • 24-bit resolution

  • Accuracy: ±0.05% at 25°C

  • Sigma-Delta conversion method

  • Reinforced isolation: 250V continuous

  • Overvoltage protection up to ±30V DC

  • Common-mode noise rejection: 120 dB @ 50/60 Hz

  • Normal-mode noise rejection: 80 dB @ 60 Hz

  • Data format: IEEE 32-bit floating point

  • Software-configurable channel scaling and alarms

  • DIN-rail mountable in a ControlLogix chassis

  • Supports mechanical and electronic keying

  • Compatible with screw or spring-clamp RTBs

Technical Specifications

  • Catalog Number: 1756-IF8I

  • Backplane Power:

    • 5.1V DC: 200 mA

    • 24V DC: 150–400 mA depending on configuration

  • Power Dissipation:

    • Voltage input mode: 4.6 W

    • Current non-sourcing: 5.1 W

    • Current sourcing: 7.3 W

  • Dimensions: Standard 1-slot ControlLogix module

  • Operating Temperature: 0 to 60°C

  • Storage Temperature: -40 to 85°C

  • Humidity: 5% to 95% non-condensing

  • Certifications: UL, CE, ATEX, KC, C-Tick

Applications

  • Process control requiring isolated analog inputs

  • Signal measurement for voltage and current transducers

  • Data acquisition in high-noise industrial environments

  • SCADA and DCS systems needing accurate analog input integration

Why Choose the 1756-IF8I?

  • High-resolution and precise input for critical control

  • Channel-to-channel isolation enhances reliability

  • Configurable per-channel input type for flexibility

  • Advanced diagnostics and alarm integration

  • Ideal for industrial environments with electrical noise
