Mechanical Mounting on DIN Rail
You can mount the 1762-OW16 on a standard DIN rail. The module measures 90 x 40.4 x 87 mm. Ensure the mounting area is clean and free of debris. This module supports both DIN rail and direct panel mounting. The total height with tabs is 110 mm. Install the module securely for stable operation.
Wiring the AC/DC Relay Outputs
This module has two isolated groups of eight outputs each. Group 0 includes outputs 0 through 7. Group 1 includes outputs 8 through 15. Use the correct wiring for your voltage category. The relay contacts are normally open. Connect your load between the common and output terminal.
Critical Load Management and Current Ratings
Each output point supports a maximum continuous current of 2.5 A. The continuous current per common is 8 A. The total module current is 16 A. For DC voltage, the 125 V rating allows 2 A per point. The 24 V rating allows 1 A per point. Plan your load distribution carefully.
Proper Surge Suppression for Inductive Loads
Connect a surge suppressor across any inductive load. This action protects the relay contacts from high inrush currents. Using surge suppressors extends the operational lifespan of your module. Follow Allen-Bradley’s wiring guidelines for best results. This step prevents damage from electrostatic discharge.
Maximum Module Capacity by Controller
The number of supported modules depends on your controller type. You can install up to four modules with a MicroLogix 1100 controller. The MicroLogix 1200 supports up to six modules. Use up to seven modules with a MicroLogix 1500 controller. This flexibility allows for significant I/O expansion.

Key Electrical Specifications for Selection
The 1762-OW16 operates on a voltage range of 5-265 VAC and 5-125 VDC. It features a signal delay of only 10 ms for all transitions. The module draws 140 mA at 5 VDC and 180 mA at 24 VDC. The maximum controlled load is 1440 VA. The minimum on-state current is 10 mA.
Understanding the Relay Contact Ratings
This module has four distinct relay contact ratings. It handles 24 VDC, 125 VDC, 120 VAC, and 240 VAC. For AC voltages, the current rating is 2.5 A per point. For 125 VDC, the rating drops to 2 A. For 24 VDC, it is only 1 A per point. Choose the correct voltage for your application.
Thermal and Environmental Tolerances
The module dissipates a maximum heat of 6.1 Watts. Its IP20 enclosure rating protects against solid objects. The shipping weight is a light 0.63 pounds. This makes it easy to handle during installation. The module design ensures reliable operation within industrial environments.
Benefits of Isolated Output Groups
The two isolated groups provide enhanced system protection. Each group supports eight channels independently. This isolation prevents a fault in one group from affecting the other. It improves the overall reliability of your control system. Use this feature to separate different load types.
Procurement Advantages for Engineers
Purchasing the 1762-OW16 guarantees seamless integration with your MicroLogix system. It provides a cost-effective method to increase output capacity. The module’s robust design ensures a long operational life. You can trust it for energizing and de-energizing critical loads. This module delivers excellent value for your automation project.
