Product Overview

The 1769-IQ16 (Catalog Number: 1769-IQ16) is a high-density discrete input module engineered for the Allen Bradley CompactLogix and MicroLogix 1500 controller platforms. This module provides 16 digital input points, acting as a reliable interface for field devices such as limit switches, proximity sensors, and push buttons.

A defining feature of the 1769-IQ16 (Part Number: 1769-IQ16) is its bipolar sink/source capability. This allows engineers the flexibility to wire the module in either a sinking (NPN) or sourcing (PNP) configuration, depending on the common return wiring. To ensure system longevity and data integrity, the module includes comprehensive optical isolation, shielding the sensitive backplane logic from industrial electrical noise and high-voltage transients.
