Part Number/Catalog Number 1756-IF16IH Model
Series ControlLogix
Module Type HART interface module
The Allen-Bradley 1756-IF16IH is a ControlLogix current analog input module family with HART protocol that can operate 225 mA at 5.1V DC and 200 mA at 24V DC voltage and current ratings. The input current ranges from 0-20 mA or 4-20 mA. The current analog input module has 16 inputs and 16-21 bit resolution. The 1756-IF16IH has a power consumption of 5.30 W and a surge current of 400 mA at 5.1V DC and 450 mA at 24V DC. In addition, it has a continuous isolation voltage of 250V, an input impedance of 250 inches (±5 inches), and an open circuit detection time of 5 seconds for the 4-20 mA range only.
The 1756-IF16IH features 28.8V DC input overvoltage protection with > 90 dB common-mode noise suppression at 50-60 Hz. In addition, the module has an input offset drift temperature of 300 iA /°C and a gain drift temperature of 20 ppm/°C. The 1756-IF16IH uses the input conversion method of Sigma-Delta ADC (24-bit converter) and has the output conversion method Sigma-Delta ADC (24-bit converter). Therefore, the typical calibration interval for this module is 12 months. The 1756-IF16IH uses either 1756-TBCH or 1756-TBS6H detachable terminals and open housing. The 1756-IF16IH works in integer mode IEEE 32-bit floating-point data format with 0.15%-1.5% full scale calibration accuracy at 25 °C (HART disabled).
