Allen-Bradley 1756-IF16H Analog Input Module HART

Allen-Bradley 1756-IF16H is a ControlLogix analog input module that adds HART communication to a 16-channel input block. It fits in a 1756 I/O backplane and is used to read analog signals from field devices, including HART-enabled transmitters that communicate on 4-20 mA loops. The module provides 16 input channels for acquiring analog data and integrates with Rockwell Automation software for configuration, tagging, and diagnostics. The HART capability enables device-level information (such as device status and loop data) to be accessed alongside the primary analog measurement, without requiring external gateways. This makes it suitable for process instrumentation applications where sensors provide both traditional analog signals and digital device information. As part of the ControlLogix 1756 I/O family, the IF16H can be mixed with other analog and digital I/O modules on the same rack, allowing scalable deployment in automation systems that require direct interfacing to HART transmitters.
