Allen-Bradley 1769-IQ32 32-Point DC Input Module

The Allen-Bradley 1769-IQ32 is a 32-point 24V DC digital input module for the Compact I/O family, designed to be mounted on a DIN rail within CompactLogix control systems. It provides high-density discrete input monitoring for field devices such as pushbuttons, limit switches, and proximity sensors, enabling scalable I/O expansion in manufacturing equipment, packaging machinery, and process automation panels. Key specifications include 32 DC inputs at 24 V DC, backplane communication to a CompactLogix controller, and channel grouping isolation (application dependent) within an industrial automation environment. Common replacements include Allen-Bradley 1769-IQ16 and 1756-IB32, as well as Siemens 6ES7221-1BH32-0XB0, highlighting its role in legacy and cross-vendor replacement contexts.
