The 1756-IF16H is a high-performance analog input module designed by Rockwell Automation, specifically engineered for use with the ControlLogix® 5000 series programmable automation controllers (PACs). It serves as a critical interface component in industrial automation systems, enabling accurate and reliable acquisition of analog sensor signals for real-time process monitoring and control.
Core Functionality
This module is classified as a 16-channel analog input module, meaning it can simultaneously receive and process signals from up to 16 independent analog sensors or transducers. It is optimized for handling high-accuracy voltage and current signals—the most common analog signal types in industrial environments. Key functional features include:
Dual-range signal support: Compatible with both voltage inputs (typically ±10V DC) and current inputs (4-20 mA DC), with configurable range settings per channel to match diverse sensor requirements.
High-resolution data conversion: Equipped with a 16-bit analog-to-digital (A/D) converter, ensuring precise signal quantization and minimizing measurement error. This resolution translates to more granular data for critical process control applications.
Isolation protection: Incorporates channel-to-channel isolation and system ground isolation, which prevents electrical noise, ground loops, and voltage transients from interfering with signal integrity. This isolation is crucial for maintaining stability in harsh industrial settings (e.g., manufacturing plants, power facilities).
