Allen-Bradley 1769-OV16 24VDC Output Module

Allen-Bradley 1769-OV16 Discrete Output Module Product Introduction

The 1769-OV16 from Allen-Bradley is a high-performance discrete output module designed for the CompactLogix and MicroLogix 1500 control platforms. This 1769-OV16 module provides sixteen sinking output channels that operate at 24V DC with a voltage range of 20.4 to 26.4V DC. Its robust current capacity reaches 1.0A per point at 30°C and 0.5A per point at 60°C, making it suitable for driving solenoids, contactors, and indicator lights. Additionally, this module features a removable terminal block with a finger-safe cover for convenient wiring and maintenance.

Technical Specifications

The 1769-OV16 offers sixteen outputs arranged in a single output group. Its output voltage range spans from 20.4 to 26.4V DC, with a nominal rating of 24V DC. Specifically, the output current per point reaches 1.0A at 30°C (86°F) and 0.5A at 60°C (140°F). Meanwhile, the module's total current capacity is 8.0A at 30°C and 4.0A at 60°C. For transient protection, the 1769-OV16 handles a surge current of 2.0A for 10 milliseconds, repeatable every 2 seconds. Notably, the output delay times are remarkably fast, with 0.1ms for the ON state and 1.0ms for the OFF state. The off-state leakage current is a maximum of 1.0mA at 26.4V DC, while the on-state voltage drop is only 1.0V DC at 1A. Furthermore, this module draws 200mA from the 5.1V backplane supply.

Mechanical and Environmental Parameters

Physically, the 1769-OV16 measures 4.65 x 1.38 x 3.43 inches (118 x 35 x 87 mm) and weighs approximately 0.61 pounds. Its open-style enclosure requires installation inside a protected control cabinet. For wiring, this module accepts copper-90°C solid wire from 22 to 14 AWG and stranded wire from 22 to 16 AWG. The shipping dimensions are 8 x 8 x 5 inches with a gross weight of 2 lbs. Additionally, the module operates reliably in 5% to 95% non-condensing humidity and dissipates a maximum of 2.06W of heat.

Installation and Mounting Guide

Mounting the Allen-Bradley 1769-OV16 is flexible, supporting both DIN rail and panel mounting options. First, connect the module to the host controller or adjacent I/O modules using the tongue-and-groove locking system. Next, secure the bus lever to lock the communication bus. Importantly, when installing in a CompactLogix system, place this 1769-OV16 module within eight modules of the power supply to meet the Power Supply Distance rating. Should you need more than eight modules, add a compatible system power supply such as the 1769-PA2, 1769-PB2, 1769-PA4, or 1769-PB4. For optimal performance, maintain adequate spacing from enclosure walls for proper ventilation. Always disconnect power before wiring and route I/O cables from below the module to the terminals.

Packaging List

Every shipment of the 1769-OV16 includes:

• One 1769-OV16 16-point sinking output module

• One removable terminal block with finger-safe cover

• One write-on identification label

Frequently Asked Questions (FAQ)

Q1: Which controllers are compatible with the 1769-OV16?
This module works seamlessly with CompactLogix controllers and also serves as expansion I/O for MicroLogix 1500 systems.

Q2: What does "sinking" wiring configuration mean for the 1769-OV16?
In sinking configuration, the output provides a path to ground (DC common) when activated, allowing current to flow from the load to the module.

Q3: How does temperature affect the output current of the 1769-OV16?
The current capacity derates with temperature. Specifically, each point delivers 1.0A at 30°C but reduces to 0.5A at 60°C, so always consider your ambient temperature when sizing loads.

Q4: How far can I place this module from the power supply?
Place the 1769-OV16 within eight modules of the power supply. For configurations exceeding this distance, add an additional system power supply to maintain proper operation.

Q5: What shipping methods are available?
We ship this Allen-Bradley module using trusted global carriers, including FedEx, UPS, and DHL, ensuring fast and secure delivery.
