Product Overview
The Allen-Bradley 1762-OB16 is a discrete output module designed for the MicroLogix family of programmable logic controllers. This solid-state module provides sixteen (16) sourcing outputs at 24 VDC, making it a cost-effective solution for expanding I/O capacity in industrial automation systems. By adding this module, you can energize actuators, pilot lights, relay coils, and other discrete devices without replacing an entire controller, reducing downtime and overall system cost.

These specifications ensure reliable switching and energy efficiency. The fast signal delays (0.1 ms on, 1.0 ms off) minimize cycle time, while the low bus current draw reduces power consumption, contributing to lower operational costs over the module's lifespan.
Industry Applications
The 1762-OB16 excels in manufacturing lines where additional output points are required for solenoid valves, motor starters, and status indicators. For example, in a packaging machine, this module can control multiple pneumatic actuators and warning lights simultaneously. In material handling systems, it reliably drives conveyor motor contactors. By integrating this module, you gain scalable I/O without upgrading the entire controller, maximizing return on investment.
Installation & Setup Guidance
Mount the Allen-Bradley 1762-OB16 on a DIN rail within a panel that has proper grounding. Maintain at least 50.8 mm (2 inches) clearance on all sides for ventilation. Connect the 24 VDC power supply (20.4–26.4 VDC range) to the module terminals. The 16 sourcing outputs share a common group; wire each load accordingly. For high-vibration environments, install a DIN rail end anchor. Ensure the module is no more than six modules away from the power supply to maintain voltage integrity.
Compatibility & Integration
The 1762-OB16 is compatible with MicroLogix 1100, 1200, and 1400 controllers. It can be installed as one of up to four expansions (MicroLogix 1100), six (MicroLogix 1200), or seven (MicroLogix 1400). The module communicates via the backplane and does not require additional communication protocol configuration. It works seamlessly with Allen-Bradley programming software (RSLogix 500 or Connected Components Workbench) for easy integration into existing control systems.
Selection Guide & Purchasing Advice
Before purchasing the 1762-OB16, verify your controller model and the number of available expansion slots. Also confirm that your power supply can handle the additional bus current (175 mA at 5V DC). For reliable long-term operation, consider stocking a spare module to minimize downtime. UBEST Automation offers genuine Allen-Bradley 1762-OB16 modules with competitive pricing and fast shipping.
