Allen-Bradley 1769-OW16 is a high-density 16-point mechanical relay output module designed for 1769 CompactLogix automation systems. As the upgraded high-channel version of the 8-point 1769-OW8/OW8I relay modules, it integrates 16 normally-open relay dry contacts in a single slot, supporting universal AC/DC mixed load switching. With large current carrying capacity and zero off-state leakage, it is the ideal cost-effective solution for high-channel-volume load control and cabinet space-saving industrial retrofit projects.

Ultra-High Density Design & Universal Relay Switching Performance

Compared with 8-channel OW8 and isolated OW8I modules, the 1769-OW16 doubles relay output channels in the same single-slot size, drastically improving cabinet I/O density and reducing overall module quantity. Adopting mechanical dry-contact structure, it breaks the limitation of single AC or DC solid-state modules, freely adapting to mixed AC and DC load devices on site.

Each channel supports 2.5A single-point large current output, capable of driving high-power loads that conventional solid-state modules cannot support, including industrial solenoid valves, contactor coils, indicator light banks and auxiliary power loops. Zero off-state leakage eliminates residual voltage risks, ensuring thorough circuit disconnection and higher operational safety. Standard group isolation design delivers stable anti-interference performance for conventional industrial workshop environments.

High-Capacity Expansion & Cost-Effective Retrofit Advantages

AllenBradley 1769-OW16 features standard 1769 backplane bus protocol and compact single-slot layout, fully compatible with all CompactLogix L2x/L3x series controllers and 1769 I/O racks. For high-channel automation projects, its 16-point high-density design greatly optimizes cabinet layout, reduces wiring workload and lowers overall system investment compared with stacking multiple 8-point relay modules.

It supports plug-and-play replacement for old low-density relay output modules without cabinet modification or program adjustment, perfectly fitting incremental factory upgrades. Matched with EtherNet/IP adapters, it realizes stable large-scale remote load switching control for distributed automation architectures, balancing high channel capacity and cost performance for mass load control scenarios.

Industrial Application Scenarios

AllenBradley 1769-OW16 is widely deployed in high-channel-volume mixed AC/DC load control scenarios, including automated assembly lines, high-speed packaging machinery, logistics sorting systems, factory auxiliary electrical loops and industrial lighting centralized control systems.

North American equipment OEMs adopt OW16 for high-density standardized machine design to save cabinet space. Latin American manufacturing factories deploy the 16-point relay module for batch actuator centralized switching control. European automation maintenance teams rely on its zero-leakage safety performance and large-load capacity to reduce equipment failure rates and long-term maintenance costs.
