Allen-Bradley 1734-4IOL 4-CH IO-Link Master Module

The Allen-Bradley 1734-4IOL is a POINT I/O 4-channel IO-Link Master Module that adds four IO-Link master channels to a Rockwell Automation POINT I/O network. Each of the four channels can be configured as an IO-Link master or as standard digital I/O, enabling flexible connection to IO-Link devices while supporting mixed-mode I/O on a single module. As part of the POINT I/O family, it installs in a POINT I/O chassis and communicates with the controller through the POINT I/O backplane within a Rockwell EtherNet/IP-compatible control system. This IO-Link Master module is designed to connect IO-Link capable sensors and actuators to a Rockwell control system, providing streamlined device management and standardized device descriptions via IODD files. Catalog number 1734-4IOL identifies a 4-channel IO-Link Master for POINT I/O, offering a compact way to extend field-device connectivity without adding separate IO-Link hardware outside the POINT I/O ecosystem. Typical use cases include bringing IO-Link sensors (for health, parameter, or diagnostics data) and IO-Link actuators into a Studio 5000-driven automation architecture, enabling centralized monitoring, configuration, and integration with existing PLC I/O maps. The device supports the Rockwell Automation approach to modular I/O, maintaining consistent wiring, diagnostics, and alignment with other POINT I/O modules for scalable, packetized control of industrial automation tasks.
