The Allen-Bradley 1756-IF16IH is a ControlLogix Current Analog Input Module designed to integrate seamlessly with the HART Protocol. Designed to operate efficiently with voltage and current ratings of 225 mA at 5.1V DC and 200 mA at 24V DC, it supports input current ranges of 0-20 mA or 4-20 mA across its 16 inputs. Featuring resolutions between 16 to 21 bits and a robust power dissipation of 5.30 W, this module provides high common mode noise rejection greater than 90 dB at 50-60 Hz. It incorporates advanced Sigma-Delta ADC conversion methods and boasts an input overvoltage protection of 28.8V DC, making it exceptionally reliable. Equipped with a continuous isolation voltage of 250V, a sophisticated input impedance, and precise open circuit detection, the 1756-IF16IH is ideal for demanding industrial applications requiring calibrated accuracy ranging from 0.15% to 1.5% at 25 °C.
