Allen-Bradley 1769-IQ16 Compact IO Digital Input Module

Allen-Bradley 1769-IQ16 is a 16-point 24 VDC digital input module for the 1769 Compact I/O family, configured as a sink/source input module for CompactLogix systems. It provides sixteen digital input channels that accept 24 VDC signals and supports both sinking and sourcing wiring configurations, enabling flexible connection to field devices. The module plugs into a 1769 Compact I/O backplane and is designed for use with CompactLogix controllers, expanding discrete input capacity in a Compact I/O rack. Typical applications include reading the status of digital sensors and switches—such as pushbuttons, limit switches, and proximity sensors—where 24 VDC signaling is standard. Detailed electrical characteristics, including the 24 VDC signaling and 16-channel configuration, are documented in the official 1769-IQ16 datasheet and cut sheet.
