Allen-Bradley 1769-IQ16 CompactLogix Digital DC I/O Module

Description

Allen-Bradley 1769-IQ16 CompactLogix Digital DC I/O Module is a compact digital input module designed for integration with the Allen-Bradley 1769 series CompactLogix controller systems, and is also compatible for expansion I/O in MicroLogix 1500 controller assemblies. It features 16 DC input channels, split into two groups of 8 channels each, enabling classification and management of input signals from industrial switches, sensors, and other digital devices, converting these signals into system-recognizable data for precise industrial process monitoring and control.

The module supports 24V DC sink/source input configurations, with a wide operating voltage range: 10-30V DC at 30 degrees Celsius, and 10-26.4V DC at 60 degrees Celsius, ensuring stable signal input across varied industrial power environments. It delivers fast response with a typical hardware delay of 8 milliseconds for both OFF-to-ON and ON-to-OFF signal transitions, enabling real-time system reaction to input changes.

Key electrical specifications include a minimum on-state input current of 2.0mA, maximum off-state input current of 1.5mA, and a 5V backplane current draw of 115mA (0.58W) for low-power, reliable operation. It also features IEC Class 2 reinforced insulation, with 75V DC isolation (tested at 1697V DC for 1 second) between inputs and bus, and between groups, plus a maximum surge current of 250mA and nominal input impedance of 3k ohms for enhanced durability in harsh industrial settings.
