CompactLogix DC Input Module 1769-IQ16 Allen Bradley

Product Description

The 1769-IQ16 is a 16-point discrete input module for Allen Bradley CompactLogix and MicroLogix 1500 controllers. Designed for reliable monitoring of industrial devices, this module interfaces with photoelectric sensors, limit switches, and auxiliary contacts, providing robust signal acquisition in electrically noisy environments. Its bipolar sink/source design and optical isolation ensure both flexibility and protection for the backplane, making it ideal for general automation tasks.

Technical Specifications

Key Features

• High-Reliability Inputs: 16 digital points in a compact module.

• Bipolar Wiring: Supports both sink (NPN) or source (PNP) sensors.

• Optical Isolation: Protects backplane from transients and electrical noise.

• Compact Design: Chassis-less modular form factor reduces control panel footprint.

• Simple Expansion: Snap-on installation for easy I/O growth.

Industrial Applications

• General manufacturing automation

• Assembly line monitoring

• Material handling and conveyor systems

• Food and beverage processing

• Operator interface and push-button stations

Frequently Asked Questions

Q: Can I mix sinking and sourcing sensors on the same module?
A: No. All 16 channels share a single common return, so all connected sensors must be of the same type (either all sinking or all sourcing).

Q: What happens if voltage drops below 10V DC?
A: The module may fail to register an “On” state reliably. Maintain the 10–30V DC range for consistent operation.

Q: Is the 1769-IQ16 hot-swappable?
A: No. The module does not support Removal and Insertion Under Power (RIUP). Always power down before replacing the module.
