Allen-Bradley 1756-OB16DK | 16-Point DC Output Module | 19–30V DC

Allen-Bradley 1756-OB16DK | ControlLogix 16-Point DC Output Module with Diagnostics (Conformal Coated)

Overview

The Allen-Bradley 1756-OB16DK is a 16-channel DC digital output module for ControlLogix systems, featuring sourcing outputs, point-level diagnostics, and a conformal coating for added protection in harsh environments. Operating at 19–30V DC, this module is ideal for industrial applications that require high reliability, environmental resistance, and real-time fault monitoring.

Each channel delivers up to 1.0 A, and the built-in field-side diagnostics simplify troubleshooting while enhancing system visibility. Its conformal coating guards against dust, moisture, and corrosive atmospheres.
