Allen-Bradley 1756-IF16 /A Analog Input Module

The Allen-Bradley 1756-IF16 /A is a Series A ControlLogix 16-point analog input module used to acquire and process multiple analog field signals in automation systems. It mounts in a 1756 ControlLogix chassis slot and communicates over the backplane, with channel-to-backplane isolation to protect the controller. The module supports voltage and current inputs selectable by application, delivering 16 analog inputs. Typical sensors include pressure transmitters, temperature sensors, flow meters, and level devices used across manufacturing plants, oil and gas facilities, water and wastewater treatment, and chemical processing. It serves as I/O expansion, replacement for failed analog cards, system upgrades, and integration of process instrumentation into PLC-based architectures. Common replacements include 1756-IF8, 1756-IF16H, and 6ES7531-7KF00-0AB0.
