Information About 1756-IF16IH
The 1756-IF16IH is part of the Allen-Bradley ControlLogix I/O family, developed for precise analog measurement and field device integration. It features 16 differential input channels with selectable current ranges of 0–20 mA or 4–20 mA, providing 16–21 bits of resolution through a 24-bit Sigma-Delta A/D converter. The module consumes 225 mA at 5.1 VDC and 200 mA at 24 VDC, with a maximum power dissipation of 5.3 W. It has an input impedance of 250 Ω (±5 Ω), open-circuit detection for 4–20 mA signals, and overvoltage protection up to 28.8 VDC. The module offers excellent noise rejection (>90 dB at 50/60 Hz) and maintains accuracy within 0.15% to 1.5% of full scale at 25 °C (HART disabled). With a calibration interval of 12 months, continuous 250 V isolation, and compatibility with 1756-TBCH or 1756-TBS6H terminal blocks, the 1756-IF16IH ensures long-term reliability. It supports both integer and IEEE 32-bit floating-point data formats, enabling integration into modern control strategies while providing advanced diagnostics and HART communication.
