IO-Link Sensors

Overview

IO-Link is a worldwide open standard protocol used for communication between devices in industrial settings. It facilitates bi-directional data exchange between a master device, actuators, and sensors. This system supports various IO-Link slave sensors, including those for pressure, temperature, humidity, and electrical power measurement. Rapid prototyping is possible using Pmod™ boards and sample code.

System Benefits​:

  • Pmod evaluation boards and software are available for rapid prototyping.
  • IO-Link PHY chips integrate LDO, reducing BOM count.
  • Multiple PHY and MCU options scale cost and performance according to application requirements.
