1791-16BO Allen Bradley I/O Input Module

Function

Receiving Digital Commands: These commands are typically based on the control logic programmed in the PLC.

Indicator Lights/Beacons: To provide visual or audible status indications.

Enabling Distributed Control: As a CompactBlock I/O module, its function is crucial in distributed I/O architectures.

Key Feature

16 Digital DC Output Points: Provides 16 independent discrete output channels, enabling the control of numerous ON/OFF devices from a single module.

Electrical Isolation: Features isolation between the outputs and the internal logic circuitry, as well as between common groups. 

Removable Terminal Strip: Utilizes a removable screw terminal strip for all wiring connections. 

Description

The Allen-Bradley 1791-16BO is a core component within Rockwell Automation's CompactBlock I/O family, specifically designed as a 16-point DC Digital Output module.This module is instrumental in creating efficient distributed I/O architectures. Instead of running numerous long wires back to a central control cabinet, the 1791-16BO allows for outputs to be placed closer to the machinery they control.
