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

The Allen-Bradley 1769-IQ16 is a 16-point, 24 VDC digital input module for the CompactLogix 1769 family that accepts both sinking and sourcing inputs, enabling flexible wiring of 24 V sensors, switches, and other DC devices in a Compact I/O chassis. It groups its inputs into two 8-point blocks, and its dimensions are approximately 118 x 35 x 87 mm with a weight around 270 g, designed to operate on a 10–30 V DC supply at 30 °C. The module draws roughly 115 mA at a 5.1 V reference, supports an 8 ms input delay for both on and off transitions, and offers an input impedance of about 3 kΩ; its input isolation is rated up to 1200 V AC for 1 s (input point to bus) and between groups, with a 75 V DC working voltage rating per IEC Class II reinforced insulation. This 16-point module is used to read discrete 24 VDC signals from sensors and switches into Rockwell Automation controllers, enabling scalable digital I/O in manufacturing and process automation workflows.
