1762-OB16 Allen-Bradley MicroLogix 16-Point 24VDC Sourcing Output Module
Product Title: 1762-OB16 Allen-Bradley MicroLogix 16-Channel 24VDC Sourcing Output Expansion Module
The Allen-Bradley 1762-OB16 is a solid-state expansion output module for the MicroLogix 1100, 1200, and 1400 families. It adds 16 sourcing 24VDC outputs in one group, outputs 0 through 15. The module suits panel builders and maintenance teams who need extra discrete outputs without changing the controller platform.
Each point switches fast: 0.1 ms ON delay and 1.0 ms OFF delay. The module draws 175 mA max at 5VDC from the bus. It uses external 24VDC input power over a 20.4 to 26.4VDC range. Use it to drive solenoids, relay coils, pilot lamps, horns, buzzers, and small motor starters.
Key point: the 1762-OB16 is a sourcing (PNP-style) output module. Check your field device wiring before you install it. For sourcing input needs, choose a different module.

Note on temperature derating: point and module current ratings fall as ambient temperature rises. Confirm your panel temperature before you set load limits. The surge rating allows one repeat every 2 s at 55°C, or once per second at 30°C, for 10 ms each time.
Compatibility Notes
- MicroLogix 1100: up to 4 expansion modules
- MicroLogix 1200: up to 6 expansion modules
- MicroLogix 1400: up to 7 expansion modules
Keep the module within six positions of the power supply. Add a second supply if your layout needs more modules. This rule protects bus voltage and stable switching.
Installation Guide
- Mount on a well-grounded surface or DIN rail.
- Leave 2 in (50.8 mm) clearance on all sides for airflow.
- Use a DIN rail end anchor in high-vibration areas.
- Keep wiring away from enclosure walls and adjacent wireways.
- Check sourcing wiring polarity before you power up.
Setup and Maintenance
The module has no user serviceable parts. Commissioning is fast. Wire the outputs, set the controller I/O map, and confirm each point with a test load. Keep spare modules on hand for critical lines. Oiltech Controls tests each unit before shipment. Contact us: info@oiltechcontrols.com or +86 158 8020 0923 for compatibility checks.
Typical Applications
- Solenoid and valve control
- Relay coil and motor starter switching
- Pilot lamps, sirens, horns, and buzzers
- Packaging, material handling, and small machine lines
- Legacy MicroLogix panel upgrades
Diagnostics
The controller handles point status reporting. Watch for output faults in the controller I/O status table. Use a meter at the terminal to confirm point voltage. If a point fails to switch, check the external 24VDC supply first, then the field wiring and load current.
