Allen-Bradley 1756-IF16 Analog Input Module

Allen-Bradley 1756-IF16 is a ControlLogix analog input module that provides 16 input points in a single slot for capturing sensor signals, wired to a 36-pin backplane interface. It accepts both voltage and current signals, with voltage inputs in the ±10 V range and current inputs in the 4-20 mA range, enabling direct measurement of common process signals without external signal conditioning. This module is designed for ControlLogix I/O racks and integrates with Rockwell Automation’s control software environment for configuration and data acquisition. A conformally coated variant is available as the 1756-IF16K for harsher environments. Operational specifications include an operating temperature range of 0 to 60 °C, 5–95% noncondensing humidity, and nonoperating conditions from -40 to 85 °C, with the broader environmental performance detailed in Rockwell’s technical data. The 1756-IF16 is documented as a 16-point analog input module supporting current/voltage measurement with a 36-pin interface, and its datasheet confirms the dual-mode input capability and the ±10 V / 4-20 mA ranges.
