The Allen-Bradley 1756-IF8H is an analog input module within the Logix controller platform, featuring eight differential voltage or current input channels and an integrated HART modem for smart device communication. Each channel can be individually configured for 0–20 mA or 4–20 mA current inputs and ±10 VDC, 0–5 VDC, 1–5 VDC, or 0–10 VDC voltage inputs, providing flexible signal handling for industrial applications. With a resolution ranging from 16 to 21 bits depending on configuration, the 1756-IF8H delivers high-accuracy measurement performance and full HART protocol support for ControlLogix process control systems.
