Allen-Bradley 1769-IQ16 16-Channel DC Input Module

The Allen-Bradley 1769-IQ16 is a CompactLogix 16-point digital input module that provides 16 independent 24V DC input channels compatible with the CompactLogix I/O backplane, and it supports both sinking and sourcing wiring configurations so field devices can be wired to suit diverse control schemes. Designed for 10–30V DC operation and using standard 22–14 AWG copper conductors (solid) or 22–16 AWG stranded, the IQ16 mounts on a DIN rail or panel and aligns with the 1769 Compact I/O mounting approach for scalable expansion in industrial cabinets. Field wiring terminates through the 1769-RTBN18 terminal block, with optional accessories such as 1769-RD or 1769-RL1 doors for labeling and enclosure integration, making it easy to organize and service in busy control rooms. As a compact digital input module in Rockwell’s 1769 family, the IQ16 is suited for sensors, limit switches, and other 24V DC devices, enabling reading 16 discrete inputs (a 16-bit word) from your controller and expanding the system’s input capacity while keeping a small footprint.
