Features:
- Dedicated output module designed for use in CompactLogix systems
- It provides 16 individual outputs and operates within a specified voltage range of 20.4 to 26.4 volts DC, making it suitable for various automation tasks
- Allen-Bradley Compact I/O 16-Channel Digital Output Module
The Allen Bradley 1769-OB16 is an output module from the CompactLogix family, providing critical functionality for automation projects. Featuring 16 outputs, it is designed for efficient control of a wide range of devices. The module operates from 20.4 to 26.4 volts DC, meeting industry standards for DC control systems. Its design incorporates a fast response time, with an output start-up delay of only 0.1 milliseconds, ensuring rapid startup of connected devices. In contrast, the turn-off delay is set to 1 millisecond, enabling synchronization of the control process.
The 1769-OB16 requires 200 mA of current at 5.1 volts, contributing to its operating characteristics. Furthermore, its excellent thermal performance and maximum power rating of 2.11 watts ensure reliable operation under load. The device's compact, single-slot design allows for DIN rail or panel mounting, meeting various installation requirements of control systems. This versatility solidifies its position as a reliable component in modern industrial environments.
The 1769-OB16 Allen Bradley Digital Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Because of its ability to provide fast and reliable 24V DC switching, the 1769-OB16 is widely used in automated machinery and production lines to drive various discrete devices:
Actuator control: Powers pneumatic and hydraulic solenoid valves to drive robotic arms, grippers, or gates.
Motor control center (MCC): Energizes the coils of intermediate relays or motor starters to start large industrial motors.
Audiovisual signals: Illuminates stack indicator lights, indicator lights, and control panel LEDs, or emits emergency alarms and buzzer sounds.
1.Output/Sinking Type: The 1769-OB16 is an output module. This means that when the channel is open, it outputs a 24V DC positive voltage from the terminals. Your field device must connect the other end directly to common DC ground.
2.Surge Protection: If you are driving an inductive load (such as a solenoid or mechanical relay coil), an external suppression diode should be connected in parallel across the load. This prevents inductive voltage spikes from damaging the module's internal transistors over time.
3.External Power Required: This module does not pass the PLC backplane's internal power supply to the field. You must connect an external 24V DC power supply to the VDC and Common terminals on the module's front panel to power the output channel.
