The Allen-Bradley 1756-IF8IH is a high-performance HART Analog I/O Module tailored for ControlLogix systems, offering eight current input channels with one HART modem per channel. Supporting HART revisions 5, 6, and 7, it features selectable input ranges from 0 to 20 mA or 4 to 20 mA, catering to various HART instruments within these ranges. With configurable data formats and a fixed resolution range of 16 to 21 bits, it excels in accurate data acquisition and communication, backed by robust diagnostic capabilities like under-range and over-range detection, open-circuit notification, and noise reduction via advanced filtering techniques.
