Module Overview – Compact Precision for Distributed Control
The Allen Bradley 1793-OB16P is a 16-point Digital Output Module from the ArmorBlock family, designed to provide high-performance discrete output control in rugged, distributed environments. Its compact and sealed design allows direct mounting on machinery, minimizing wiring complexity and control cabinet space.
This module delivers reliable 24V DC sourcing outputs, ideal for controlling solenoids, contactors, and indicator lamps. Built for on-machine applications, it enhances operational efficiency by integrating control directly at the field level while maintaining robust communication with higher-level controllers through DeviceNet or other supported networks.
