Product Overview

The Allen-Bradley 1762-OB16 is a MicroLogix expansion I/O module that provides sixteen 24VDC sourcing output channels. It belongs to the MicroLogix 1200 series and is compatible with MicroLogix 1100, 1200, and 1400 controllers. This solid-state module delivers reliable performance for controlling discrete actuating devices such as solenoids, pilot lamps, and motor starters.

Each output channel supports a continuous current of 0.5A at 55°C and 1.0A at 30°C. The module operates with an input supply voltage range of 20.4-26.4VDC and draws a maximum bus current of 175mA at 5VDC. The **1762-OB16** uses sourcing wiring configuration and offers signal delay of 0.1ms on and 1.0ms off.

Application Scenarios

This output module is ideal for industrial automation systems requiring additional discrete outputs beyond the built-in I/O of MicroLogix controllers. Typical applications include conveyor control, packaging machines, material handling, and light manufacturing. It energizes solenoids, relays, indicators, alarm horns, and small DC motors.

Installation & Maintenance Guide

Mount the **1762-OB16** on a DIN rail or panel. In high-vibration environments, use a DIN rail end anchor. Ensure the mounting surface is grounded properly. Maintain at least 50.8mm clearance from enclosures and wireways for adequate airflow. Do not install more than 6 modules away from the power supply; use an additional power supply if needed. Wiring connections should follow sourcing configuration with a common return. The module does not require periodic maintenance but should be inspected for dust and loose connections.
