Allen-Bradley 1769-IQ6XOW4 Compact I/O Digital Combo Module — 6 Pt 24V DC In / 4 Pt Relay Out

Product Overview

The Allen-Bradley 1769-IQ6XOW4 is a combination digital input/output module belonging to the Rockwell Automation 1769 Compact I/O platform, purpose-built for integration with CompactLogix and MicroLogix 1500 (1769 expansion) programmable logic controllers. This space-efficient module consolidates six (6) 24 V DC sinking/sourcing discrete input channels and four (4) mechanically isolated normally-open (Form A) relay output channels into a single standard-width Compact I/O housing, making it an ideal solution for machines or process skids that require a modest mix of digital sensing and control without consuming two valuable rack slots. The Allen-Bradley 1769-IQ6XOW4 communicates with the host controller via the 1769 backplane bus and is automatically recognized and configured within Rockwell Software RSLogix 5000 / Studio 5000 Logix Designer, where the six input bits and four output bits are mapped into the controller’s I/O image table for fast, deterministic scanning.Each of the six DC inputs on the Allen-Bradley 1769-IQ6XOW4 accepts a nominal 24 V DC signal in the range of 10–30 V DC, with jumper-free sink (NPN) or source (PNP) wiring flexibility—simply connect the common terminal to 0 V or +24 V as dictated by the field device. The four relay outputs are true dry contacts rated for switching both AC (5–265 V AC) and DC (5–125 V DC) loads up to 2.0 A per point (8.0 A max per module), providing versatile interfacing to pilot lights, small motor starters, solenoid valves, and audible alarms. Optical isolation separates the input group, output groups, and backplane circuitry, protecting the controller from ground loops and transient voltage spikes on the field side.Housed in a rugged, UL 508 / CE-compliant enclosure with a removable finger-safe terminal block (RTB) and individual channel-status LEDs, the Allen-Bradley 1769-IQ6XOW4 mounts directly onto a standard 35 mm DIN rail or panel via tongue-and-groove interlocking with adjacent 1769 modules. Its compact footprint—only 35 mm (1.38 in.) wide—helps minimize control-cabinet real estate while delivering the mixed-signal flexibility that small-to-medium machine builders and system integrators demand for cost-effective, scalable automation architectures.

Main Features and Advantages

Mixed-Signal Density in One Slot:The Allen-Bradley 1769-IQ6XOW4 combines six DC digital inputs and four relay outputs in a single module width, eliminating the need to allocate separate slots for small quantities of DI and DO points. This is particularly valuable in CompactLogix systems limited to 8 or 16 local I/O modules, allowing designers to reserve remaining slots for specialty analog, high-speed counter, or communication modules.Universal 24 V DC Sink/Source Inputs:Each input channel on the Allen-Bradley 1769-IQ6XOW4 can be wired for either sinking (NPN—sensor switches to 0 V, common tied to +24 V) or sourcing (PNP—sensor switches to +24 V, common tied to 0 V) operation simply by how the input common (ICOM) terminal is connected. No DIP-switch changes or jumpers are required, which simplifies panel wiring standardization and spare-part inventory management across projects using PNP or NPN proximity switches and pushbuttons.Versatile Relay Outputs for AC/DC Loads:The four electromechanical relay outputs of the Allen-Bradley 1769-IQ6XOW4 are dry contacts capable of switching both alternating and direct current loads from 5 V up to 265 V AC or 125 V DC. This universal load-compatibility lets a single module control 24 V DC indicator lamps, 120 V AC solenoid valves, or 240 V AC small contactors—all from the same card—without requiring separate solid-state output modules for different supply voltages.Galvanic Isolation and Noise Immunity:Optical coupling isolates the 1769 backplane bus, input circuits, and output groups from one another at 1200 V AC, providing robust protection against ground loops, inductive kickback from field devices, and electrical noise prevalent in industrial environments. The input channels incorporate hardware filtering (approx. 8 ms) to reject contact bounce and transient false triggers from mechanical switches or relay contacts in the field wiring.
