Allen-Bradley 1756-OG16 ControlLogix 16-Point TTL Output Module

The Allen-Bradley 1756-OG16 is a 16-point Transistor-Transistor Logic (TTL) output module for ControlLogix systems. Operating at 5V DC (Low/True), it offers high-speed signal switching with a 450μs delay and 30G shock resistance, making it ideal for precision electronic interfacing in industrial environments.

Product Description

The Allen-Bradley 1756-OG16 functions as a high-density digital output solution within the ControlLogix® platform. Specifically designed for Transistor-Transistor Logic (TTL) applications, this module provides sixteen independent outputs that operate on a 5V DC negative logic (Low/True) basis. Because it integrates directly into any standard ControlLogix chassis, it allows the controller to interface seamlessly with specialized industrial electronics, such as high-speed encoders, custom circuit boards, and laboratory instruments that require precise TTL signaling.

Stability remains a priority for the 1756-OG16, as evidenced by its robust thermal management and power efficiency. The module draws minimal current from the backplane—utilizing only 210mA at 5.1V DC—which helps maintain the overall power budget of the chassis. Furthermore, the module features a sophisticated electronic design that minimizes OFF-state leakage current to a maximum of 0.1mA, ensuring that connected devices do not receive “ghost” signals when the output is deactivated.

To ensure long-term reliability in demanding factory environments, Allen-Bradley built the 1756-OG16 with an impressive 30G shock rating. It effectively resists industrial vibration and operates consistently in temperatures up to 60°C. Additionally, the module supports advanced software features through the Studio 5000 Logix Designer® environment, including comprehensive module diagnostics and configurable output states for whenever a communication fault occurs.
