The 1769-OA16 is a discrete AC output module designed for industrial automation systems. It provides 16 output channels arranged in two groups of eight. Each group shares a common return, offering flexibility for different load configurations. This module operates on a wide voltage range of 85–264 VAC, making it suitable for global applications. Furthermore, it is fully compatible with CompactLogix and MicroLogix 1500 controllers. You can rely on this module for driving contactors, solenoids, indicators, and other AC-powered devices.
The 1769-OA16 delivers a nominal output of 120 VAC or 240 VAC. Its operating range extends from 85 VAC to 264 VAC at 47–63 Hz. Each point supports a continuous current of 0.5 A at 30°C and 0.25 A at 60°C. The module’s total continuous current per group is 2 A at 60°C and 4 A at 30°C. Additionally, the surge current rating reaches 5 A per point for short durations. This capability handles inrush loads from inductive devices effectively. The on-state voltage drop is a low 1.5 VAC maximum at 0.5 A, minimizing power loss.
This output module draws 225 mA from the 5.1V DC backplane. Its heat dissipation is rated at 4.9 W, which should be considered in your panel thermal calculations. The off-state leakage current is 2.0 mA at 132 VAC and 2.5 mA at 265 VAC. This low leakage prevents false triggering of sensitive loads. The output delay time is ½ cycle for both turn-on and turn-off transitions. Therefore, the module responds quickly to control commands from the processor.
The 1769-OA16 features two electrically isolated output groups. Each group contains eight channels with a shared common terminal. This arrangement allows you to power different voltage sources for each group. For instance, you can connect Group 1 to a 120 VAC supply and Group 2 to a 240 VAC supply. Nevertheless, ensure that the total current per group does not exceed the specified limit. Use copper wire rated for 90°C with sizes of 22–14 AWG for solid or 22–16 AWG for stranded conductors. Proper wire termination ensures reliable connections and reduces heat buildup.
The 1769-OA16 operates within a temperature range of 0°C to 60°C (32°F to 140°F). Storage temperatures can span from -40°C to 85°C (-40°F to 185°F). The module tolerates 5G vibration at 10–500 Hz and withstands 30G operational shocks. Its open-style enclosure is suitable for installation in clean, dry locations. For altitude, the maximum operating height is 2000 meters (6561 feet). Moreover, the relative humidity range is 0–95% non-condensing, ensuring stable performance in humid environments.
The 1769-OA16 is part of the 1769 Compact I/O product line. It connects directly to CompactLogix controllers via the backplane. It also works with MicroLogix 1500 systems using the appropriate expansion cable. Up to 8 modules can be placed away from the power supply based on the distance rating. This flexibility helps you distribute I/O across larger panels. Additionally, the module supports hot-swapping in certain systems, reducing downtime during maintenance.
The front panel includes 16 individual LED indicators, one per output channel. These LEDs show the on/off status of each point at a glance. A green LED indicates an active output, while an off LED signifies a de-energized channel. This visual feedback speeds up troubleshooting and verifies field device operation. Furthermore, the module communicates fault conditions to the controller via the backplane. You can then program logic to handle abnormal events.
The 1769-OA16 is commonly used in packaging, material handling, and HVAC systems. It drives AC contactors for motor starters and solenoid valves for fluid control. It also energizes pilot lamps and alarm horns in panel displays. Because it supports both 120 VAC and 240 VAC, it fits machinery exported to different regions. For legacy system upgrades, this module offers a drop-in replacement with enhanced diagnostics.

1. What voltage range does the 1769-OA16 support?
The 1769-OA16 operates from 85 VAC to 264 VAC at 47–63 Hz. This covers both 120 VAC and 240 VAC nominal systems.
2. How many output groups does this module have?
It has two isolated groups. Each group contains eight output channels with a shared common terminal.
3. Can I use this module with a MicroLogix 1500 controller?
Yes. The 1769-OA16 is fully compatible with MicroLogix 1500 systems. You need an appropriate expansion cable for connection.
4. What is the maximum current per output point?
Each point supports 0.5 A continuously at 30°C. At 60°C, the rating decreases to 0.25 A per point.
5. Does the module have short-circuit protection?
The 1769-OA16 does not include built-in short-circuit protection. You should use external fuses or circuit breakers for each group to protect the wiring and loads.
