Allen Bradley 1791-16BC Block I/O Module

Product Introduction

The Allen-Bradley 1791-16BC Block I/O Module is an integrated digital I/O module designed for industrial automation systems requiring both input monitoring and output control within a single unit. Developed by Rockwell Automation and part of the Allen-Bradley Block I/O family, this module offers a practical solution for compact and efficient control architectures.

It provides 16 digital input channels and 16 digital output channels, supporting a 10–30 VDC input range with a standard 24 VDC operating voltage. The integrated block structure significantly reduces wiring complexity and simplifies installation, making it suitable for machine-level control and distributed automation systems.

Designed for reliability and ease of deployment, the 1791-16BC is commonly used in applications where space optimization and system integration are critical.
