Allen-Bradley 1791DS-IB16 | Guard I/O Safety Input Module

Product Overview

The 1791DS-IB16 from Allen-Bradley is a Guard I/O safety input module designed for industrial automation systems. It belongs to the 1791ES and 1791DS series and features 16 single-channel safety inputs for precise monitoring of critical control points.

This module supports operation within a voltage range of 20.4–26.4V DC and draws 85 mA at 24V DC. It integrates seamlessly into DeviceNet networks, providing reliable communication and robust safety monitoring. The compact module weighs 1.00 lbs (0.45 kg), allowing easy installation in control panels with limited space.

The 1791DS-IB16 ensures safe and efficient operation by protecting against short-circuiting and providing current-sinking safety inputs plus current-sourcing pulse test outputs. Its on-state input current is approximately 3.3 mA, while the off-state current is around 1.3 mA, optimizing both performance and energy efficiency.
