Allen-Bradley 1756-OG16 Transistor Logic Output Module

The Allen-Bradley 1756-OG16 serves as a specialized digital output interface within the ControlLogix platform. This module provides sixteen distinct points designed specifically for Transistor-Transistor Logic (TTL) signaling. It effectively bridges the controller backplane with low-voltage electronic devices. Furthermore, the unit fits into any slot of a standard 1756 chassis. It utilizes a 5V DC voltage level to execute precise switching commands. This capability makes it indispensable for interfacing with high-speed electronic circuits or specialized sensors.

Operational Characteristics and Switching Speed

Efficiency defines the performance of this output module. It operates with a “Low/True” logic configuration across its channels. Each point transitions from an OFF to ON state in approximately 450μs. Conversely, the transition back to OFF takes roughly 700μs. These rapid response times ensure high-speed data transmission for sensitive automated tasks. Additionally, the hardware maintains a maximum current load of 24mA per individual point. Total module current capacity reaches 384mA to support multiple active loads simultaneously.
