The Allen-Bradley 1756-IF8H is a ControlLogix eight-channel HART analog input module that provides eight differential analog inputs for reading HART-enabled transmitters within a 1756 I/O chassis. It features a 36‑pin backplane interface and channel‑level differential input capability designed for HART current/voltage signals alongside standard analog values. Each channel exposes HART secondary process variables and transmitter health data, enabling integrated diagnostics and real‑time process visibility directly from the ControlLogix system.
