Allen-Bradley 1734-4IOLK IO-Link Master Module

Allen-Bradley POINT I/O 1734-4IOLK is a four-channel IO-Link Master Module in the POINT I/O family (Series B) that enables direct integration of IO-Link devices with a Rockwell Automation control system. It provides four IO-Link master channels that connect IO-Link slaves—such as sensors and actuators—to a PLC project through the POINT I/O backplane, streamlining device provisioning and data exchange within a scalable I/O network. Catalog numbers for this module include 1734-4IOL and 1734-4IOLK, Series B, underscoring its role as a 4-channel IO-Link Master in the 1734 POINT I/O lineup. Each of the four channels can be configured as an IO-Link master port or used as standard digital I/O, offering flexible deployment where IO-Link devices and discrete inputs share a single module. Designed for industrial environments, the 1734-4IOLK integrates with Rockwell software tools for configuration and device management, enabling straightforward setup, device description (IODD) handling, and parameterization of compatible IO-Link slaves while leveraging the modular, scalable POINT I/O architecture.
