1794-IB16 Allen-Bradley 16-Channel DC Input Module

Product Overview

The 1794-IB16 is a Flex I/O discrete input module from Allen-Bradley. It features sixteen 24VDC sinking input channels. This module works with terminal bases like 1794-TB3, 1794-TB3S, and others. It uses 1794 Flex I/O adapters for distributed I/O. Distributed architecture reduces cable runs and costs. The 1794-IB16 mounts on a DIN rail or panel. It has 16 yellow LEDs for status.

Application Scenarios

Use the 1794-IB16 in factory automation. It suits machine control and process lines. Place it near sensors or switches. This saves wiring and simplifies maintenance. Compatible with ControlNet, DeviceNet, and EtherNet/IP networks. It works with 1794-ADN, 1794-ASB, and 1794-AENT adapters.
