The 1791D-16B0X is a 16-point discrete expansion input module belonging to the Allen-Bradley CompactBlock I/O product line. Designed to operate within DeviceNet industrial communication networks, this 24 VDC block expansion module provides reliable signal data collection for distributed machine control architectures. It features sixteen sinking digital inputs grouped for efficient industrial automation system integration.

Input Channel Architecture

The module features sixteen discrete input channels configured for sinking signals operating at a nominal 24 VDC. These inputs are organized into two groups of eight channels to facilitate logical separation and wiring management. It efficiently processes field device status while maintaining high noise immunity in demanding industrial environments.

Network Communication and Power

Operating over the DeviceNet network protocol, the unit enables seamless data exchange using polled, cyclic, or change-of-state messaging. It receives operational power directly through the network architecture, minimizing external wiring requirements and streamlining cabinet layouts for distributed control setups.
