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

Allen-Bradley 1734-4IOL is a POINT I/O 4‑channel IO-Link Master Module designed to connect IO-Link devices to a Rockwell Automation control system. It provides four independent IO-Link master channels on a single module, enabling direct communication with IO-Link sensors and actuators via the POINT I/O backplane. As a member of the POINT I/O family, it is installed in a POINT I/O chassis and is powered from the standard 24V DC Point I/O power rail, with the controller interfacing through the 1734 backplane. This module supports IO-Link device configuration through IODD files and can be integrated with Studio 5000 using the Add‑On Profile for IO-Link Master devices; typical workflow includes registering device IODD files and mapping IO-Link data to controller tags. Applications include factory instrumentation and process automation where quick sensor replacement, extended diagnostics, and centralized data collection for IO-Link devices are valuable. The part number 1734-4IOL identifies a four-channel IO-Link Master, enabling scalable expansion of IO-Link device integration in Rockwell‑based control architectures.
