Allen-Bradley 1769-OW16 Relay Output Module

Allen-Bradley 1769-OW16 Relay Output Module Product Introduction

The 1769-OW16 from Allen-Bradley is a high-density relay output module designed for the CompactLogix and MicroLogix 1500 control platforms. This 1769-OW16 module provides sixteen normally open (Form A) relay contacts organized into two isolated groups of eight channels each. Its wide operating voltage range of 5 to 265V AC and 5 to 125V DC makes it suitable for switching various industrial loads, including solenoids, motor starters, and pilot lights. Furthermore, the group isolation feature allows each group to operate at different voltage levels, offering exceptional application flexibility.

Technical Specifications

The 1769-OW16 offers sixteen normally open outputs arranged in two groups, with outputs 0 through 7 in Group One and outputs 8 through 15 in Group Two. Its operating voltage spans from 5 to 265V AC and 5 to 125V DC, accommodating both AC and DC control circuits. Specifically, the contact ratings include 7.5A at 240V AC (make) and 0.75A at 240V AC (break), along with 0.22A at 125V DC. The maximum continuous current per point reaches 2.5A, while the maximum per common is 10A, and the total per module is 20A. Notably, the signal delay for both ON and OFF states is 10ms for resistive loads. The 1769-OW16 draws 205mA from the 5.1V bus and 180mA from the 24V bus, with a total heat dissipation of 4.75W. Additionally, the off-state leakage current is 0mA, and the minimum on-state current is 10mA at 5V DC.

Mechanical and Environmental Parameters

Physically, the 1769-OW16 measures 4.65 x 2.07 x 3.43 inches, increasing to 5.43 inches in height when using the 138mm mounting tabs. Its open-style enclosure requires installation inside a protected control cabinet. The shipping weight is 2 lbs with dimensions of 8 x 8 x 5 inches. For wiring, this module accepts copper-90°C solid wire from 22 to 14 AWG and stranded wire from 22 to 16 AWG. The operating temperature range is 0 to 60°C, with a non-condensing humidity range of 5% to 95%. Moreover, the 1769-OW16 withstands operating shocks of 30G and operating vibrations of 2G, ensuring reliable performance in demanding environments.

Installation and Mounting Guide

Mounting the Allen-Bradley 1769-OW16 is straightforward, 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 fully to lock the communication bus. Importantly, this 1769-OW16 module must be placed within eight modules of the power supply to meet the Power Supply Distance rating. Compatible power supplies include the 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. For configurations exceeding this distance, add an additional system power supply. The module occupies a single slot in the CompactLogix chassis or mounts as expansion I/O for the MicroLogix 1500. Furthermore, the 1769-OW16 can be used with a 1769-ADN DeviceNet adapter or a 1769-AENTR Ethernet adapter for distributed I/O applications.

Packaging List

Every shipment of the 1769-OW16 includes:

• One 1769-OW16 16-point relay 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-OW16?
This module works seamlessly with CompactLogix controllers and also serves as expansion I/O for MicroLogix 1500 systems. Additionally, it works with 1769-ADN DeviceNet and 1769-AENTR Ethernet adapters.

Q2: What voltage levels can the 1769-OW16 handle?
The 1769-OW16 handles a remarkably wide range from 5 to 265V AC and 5 to 125V DC, making it suitable for both low-voltage and high-voltage industrial applications.

Q3: What does "isolated output groups" mean for the 1769-OW16?
The two groups of eight outputs are individually isolated, which means each group can operate at different voltage levels. For instance, Group One might switch 24V DC while Group Two switches 120V AC simultaneously.

Q4: How far can I place this module from the power supply?
Place the 1769-OW16 within eight modules of the power supply. For configurations requiring more than eight modules, add an additional system power supply such as the 1769-PA2 or 1769-PB4.

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.
