Allen-Bradley 1769-OV32T 32-Point Sinking Output Module
Reliable 24V DC Output for CompactLogix Systems
The 1769‑OV32T delivers 32 sinking outputs in groups of 16. It accepts 10.2–26.4V DC power. You can use this module with MicroLogix 1500 controllers, 1769‑OV32T compatible adapters like the 1769‑ADN DeviceNet adapter, or CompactLogix controllers. Therefore, it offers great flexibility for automation layouts.
Additionally, this module has a high‑density design. It saves space on your DIN rail or panel. The tongue‑and‑groove connectors simplify system assembly. They also allow daisy‑chaining with other 1769 series I/O modules.
Technical Specifications of the 1769-OV32T
Outputs: 32 points, sinking type, grouped as 16 per common
Voltage range: 10.2–26.4V DC (nominal 24V DC)
Wire type: Copper, 90°C rated

Furthermore, the 1769‑OV32T uses solid‑state switching. This ensures fast response and long life. It consumes very little power internally. The operating temperature range suits industrial environments.
Mechanical & Environmental Ratings
This module weighs about 450 grams. Its compact single‑wide form factor occupies minimal panel space. Specifically, the open enclosure requires careful installation. Avoid conductive dust, moisture, and direct sunlight.
Meanwhile, the operating temperature range is 0°C to 60°C (32°F to 140°F). Storage temperature goes from -40°C to 85°C (-40°F to 185°F). Relative humidity can be 5% to 95% non‑condensing. Thus, the 1769‑OV32T works reliably in most factory floors.
Installation Guide for the 1769-OV32T
First, mount the module on a DIN rail or panel. Use the built‑in tongue‑and‑groove connectors to attach adjacent modules. Next, secure the module with the locking tabs. Then, connect your 24V DC power supply to the correct terminals.
For wiring, use copper wire with 90°C insulation. Strip solid wire 22‑14 AWG or stranded wire 22‑16 AWG. Torque terminals to 0.5‑0.6 N·m (4.4‑5.3 lb‑in). Consequently, you avoid loose connections. Finally, test output channels before full operation.
⚠️ Because the 1769‑OV32T has an open enclosure, always install it inside a clean control cabinet. Protect it from metal chips, liquids, and static discharge.

Frequently Asked Questions (FAQ)
1. Is the 1769‑OV32T compatible with MicroLogix 1500?
Yes, the 1769‑OV32T works directly with MicroLogix 1500 controllers using the 1769 bus.
2. What does “sinking output” mean for this module?
Sinking output means the module switches the DC common side. The load connects between the positive supply and the output terminal.
3. Can I use stranded wire larger than 16 AWG?
No, stranded wire must be 22‑16 AWG. Solid wire can be 22‑14 AWG. Larger wire may damage the terminal block.
4. How do I protect the open enclosure of the 1769‑OV32T?
Install it inside an IP54 or higher rated cabinet. Keep away from dust, moisture, and UV radiation.
5. Does the module support hot swapping?
No, you must disconnect power before removing or inserting the 1769‑OV32T to avoid damage.
