1. Introduction
1.1 Purpose
The IOL Core4 is a compact IO-Link® 1) master module designed for integration into embedded host systems. It provides four IO-Link ports compliant with IEC 61131-9 (SDCI), enabling direct connectivity to industrial sensors and actuators in IIoT and automation applications.
This Integration Manual describes the hardware interface of the IOL Core4 and provides all information necessary to integrate the module into a host system. It covers the electrical interface, mechanical dimensions and mounting, connector pinouts, and relevant operating conditions.
The document is intended for hardware engineers and system integrators who are developing host boards or carrier systems for the IOL Core4. Readers are expected to be familiar with standard embedded hardware design practices, including SPI communication and PCB layout for mixed-signal systems.
This manual does not cover firmware integration or IO-Link protocol stack configuration.
The following signs will guide you for dedicated areas of interest. The content is relevant for safe operation of the IOL Core4.
