Allen-Bradley 1769-IQ32 32-Point Digital Input Module – CompactLogix 1769 Series
Imagine a high-speed packaging line grinding to a halt because a single digital input module fails to register sensor signals — conveyor belts stop, safety interlocks trip, and every minute of downtime costs thousands. The Allen-Bradley 1769-IQ32 is the frontline defense against exactly this scenario. As the primary interface between field-level sensors and the CompactLogix controller, it translates the physical world — pushbuttons, proximity switches, photoelectric sensors, and limit switches — into the precise digital signals your PLC logic depends on. Without a reliable 32-point input module in this slot, your entire control architecture is blind.
Within the CompactLogix 1769 family, the 1769-IQ32 occupies a critical density tier: 32 points of 24V DC sink/source input capacity in a single compact module footprint. This makes it the preferred choice for machine builders and system integrators who need to maximize I/O density without expanding the rack. Globally, the 1769 series is one of the most widely deployed compact PLC platforms across automotive, food & beverage, material handling, and discrete manufacturing — making the 1769-IQ32 one of the most sourced spare and replacement modules in the industrial automation aftermarket.
