Allen-Bradley 1769-IQ16 16-Channel Input Module

Allen-Bradley 1769-IQ16 is a 16-channel 24 VDC digital input module in the 1769 Compact I/O family, designed to read status from sensors and switches with sinking or sourcing wiring for flexible field connections to CompactLogix or MicroLogix backplanes. The module provides 16 input points (two groups of eight) capable of handling 24 VDC signals, with an operating voltage range of 10–30 V DC at 30 °C (10–26.4 V DC at 60 °C), and typical input delays of 8 ms on and 8 ms off; backplane current is about 115 mA at 5 V, input impedance ~3 kΩ, and isolation between input points and the backplane is 1200 V AC / 1697 V DC with a 75 V DC working voltage rating. Dimensions are approximately 118 x 35 x 87 mm and it weighs around 270 g. It mounts on a DIN rail or panel and is powered via a 1769-PA2/PA4 or 1769-PB2/PB4 power supply, with an 8-module backplane distance rating; some listings describe the unit as open-front with no door included. Typical applications include monitoring digital sensors, pushbuttons, and limit switches in automation panels and distributed I/O for CompactLogix controllers.
