Specification

The Allen-Bradley 1756-IF16H is a high-performance analog input module designed for demanding industrial automation applications within the ControlLogix platform. This module features 16 isolated differential inputs, each with 16-bit resolution, ensuring accurate and reliable data acquisition from sensors, transmitters, and thermocouples. Its robust channel-to-channel isolation (500V DC) minimizes electrical noise and ground loop interference, making it ideal for process control, power generation, and oil and gas environments. The module supports multiple signal ranges including voltage and current inputs, and is fully compatible with standard ControlLogix chassis and Studio 5000 engineering software. With a fast scan rate of 10 ms per module, the 1756-IF16H delivers real-time performance for critical loops.
