Allen Bradley 1756-IF8 Analog Input Module

The AB 1756-IF8 is an analog input module for the ControlLogix platform, designed to provide high-precision analog signal acquisition in voltage and current formats. It features 8 input channels, each configurable for either ±10V or 0–20mA input ranges, with 16-bit resolution to support accurate measurement and control in process automation environments.

The 1756-IF8 is chassis-mounted and uses a plug-in connection for fast installation and maintenance. With its wide signal compatibility and robust design, the module is ideal for monitoring analog transducers such as pressure, flow, and temperature transmitters in industrial systems.
