Product Description

The Allen-Bradley 1762-OB16 is a 16-point, 24V DC digital output module designed for use with the MicroLogix 1200 programmable logic controller (PLC). This module allows your MicroLogix 1200 controller to send discrete (on/off) signals to various field devices in your industrial system. It features 16 individual output points, capable of switching 24V DC loads. The “OB” in its catalog number signifies it’s an “Output” module, and “B” often indicates a sinking output, meaning it provides a path for current to flow from the load back to the power supply’s common. It’s an essential component for controlling solenoids, indicator lights, small relays, and other discrete actuators.

Precautions

• Output Current Limits: Ensure that the current draw of each connected load does not exceed 0.5A per point and that the total current for the module does not exceed 4.0A. Exceeding these limits can damage the module.
• External Power Required: The outputs require an external 24V DC power source for the field devices. This power supply must be adequately sized for all connected loads.
• Wiring Best Practices: Always follow proper industrial wiring standards. Use the correct wire gauge and ensure all connections are secure to prevent loose wires and intermittent operation.
• Load Type: The 1762-OB16 is a digital output module designed for discrete (on/off) loads. Do not connect analog or continuous control devices directly.
• Environmental Conditions: Install the module within a suitable enclosure that protects it from excessive dust, moisture, vibration, and extreme temperatures to ensure optimal performance and longevity.
• ESD Protection: Always follow Electrostatic Discharge (ESD) precautions when handling the module to prevent damage to sensitive electronic components.

Product Applications

The Allen-Bradley 1762-OB16 is widely used in various industrial automation applications where discrete 24V DC output control is needed with MicroLogix 1200 PLCs. Common applications include:
