Allen-Bradley | 1756-IF16H | ControlLogix (1756)

Product Description: Allen-Bradley 1756-IF16H

The Allen-Bradley 1756-IF16H is a high-density analog input module with HART communication support, designed for ControlLogix systems. It features 16 differential analog input channels that can be configured individually for either 0–20 mA or 4–20 mA signals. The module enables simultaneous analog signal processing and HART digital communication, allowing configuration, diagnostics, and monitoring of HART field devices directly through the control system.
