IO-Link With Digital Output and DC/DC Reference Design


Design files


This reference design demonstrates the ability to have a high-density, IO-Link transceiver module, digital output (DO) (1) channel, and a DC-DC buck converter. With the DC-DC this module can power a wide array of external devices, such as microcontrollers (MCUs), sensors, displays, and more. IO-Link and DO communication channels offer a wide range of flexibility for different applications. This reference design will fit applications that require a combination of sensors, such as a flow meters, level sensors, motion sensors, light sensors, or ultrasonic sensors. The TIOL111 and TIOS101 have high tolerances to ESD as outlined in IEC 61000-4-4 and IEC 61000-4-5 (500 Ω), allowing them to be used in industrial settings where there is a potential for high amounts of ESD. With the addition of transient voltage suppression (TVS) diodes, the level of ESD protection can be raised substantially. This reference design only implements the physical layer of IO-Link.

  • IO-Link and Digital Output (M12 Type A)
  • 10-pin header for MCU and external devices
  • Power output of 500 mW
  • Designed to meet with: ± 16 kV IEC 61000-4-2, ± 4 kV IEC 61000-4-4, ± 1.5 kV/40 Ω IEC 61000-4-5

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
