Allen-Bradley 1769-OG16 TTL Output Module Product Introduction
The 1769-OG16 from Allen-Bradley is a digital output module designed for precision control in low-voltage applications. As part of the CompactLogix series, this 1769-OG16 module offers 16 TTL output channels that operate at a nominal 5V DC. It is an ideal solution for interfacing a PLC with solid-state relays, LED indicators, and other logic-level devices. Furthermore, its open-style enclosure requires installation within a protected control cabinet to ensure reliable operation.
Technical Specifications
This module provides 16 output points with a guaranteed on-state voltage between 0 and 0.4V DC. Meanwhile, its guaranteed off-state voltage falls between 4.5 and 5.5V DC. Notably, neither output state is guaranteed when the 1769-OG16 operates between 0.4 and 4.5V DC. The maximum current per point reaches 24 mA, while the minimum load current is only 0.15 mA. Additionally, the module offers 1200V AC isolation for 2 seconds between output points and the bus. Its signal delay is a swift 0.25 ms, ensuring responsive control.
Mechanical and Environmental Parameters
Physically, the 1769-OG16 measures 4.65 x 1.38 x 3.43 inches (118 x 35 x 87 mm). Its open-style enclosure makes it lightweight, with a shipping weight of just 2 lbs. For wiring, it accepts solid copper wire sizes from 22 to 14 AWG and stranded wire from 22 to 16 AWG. The shipping dimensions are 8 x 8 x 5 inches. Therefore, plan your cabinet layout accordingly to accommodate these compact but precise measurements.
Installation and Mounting Guide
Mounting the Allen-Bradley 1769-OG16 is straightforward, as it supports both DIN rail and panel mounting. First, connect the module to the host controller or adjacent I/O modules using the tongue-and-groove slots. Next, secure the bus lever fully to the left to lock the communication bus. Then, install an end cap, such as the 1769-ECR or 1769-ECL, to properly terminate the serial bus. For optimal thermal performance, maintain a 50mm (2 in.) spacing from enclosure walls and other equipment. Importantly, always disconnect power before wiring to prevent any potential damage. Also, never use a DC or I/O cable longer than 30 feet, and avoid connecting more than two wires to any single terminal.

Frequently Asked Questions (FAQ)
Q1: What controllers are compatible with the 1769-OG16?
This module works seamlessly with CompactLogix controllers. Moreover, it can also serve as expansion I/O for MicroLogix 1500 systems.
Q2: Why does the 1769-OG16 have an open enclosure?
This design choice keeps costs down for panel mounting. Consequently, you must install the 1769-OG16 inside a protected industrial enclosure to shield it from dust, static, and UV light.
Q3: What is the maximum cable length for this module?
For reliable signal integrity, never use DC or I/O cables longer than 30 feet (approximately 9 meters) with the 1769-OG16.
Q4: Can I connect multiple wires to one terminal?
For safety and reliability, please do not connect more than two wires to any single terminal block on the 1769-OG16.
Q5: What shipping methods are available?
We ship this Allen-Bradley module using trusted global carriers, including FedEx, UPS, and DHL, to ensure fast and secure delivery.
