Description
IO-Link is standardised IO technology (IEC 61131-9)
for the communication with actuators. The point-to-point
communication is based on the long established actuator
connection without additional requirements regarding the cable
material. IO-Link is no fieldbus but the further development of
the existing, tried-and-tested connection technology for
actuators.

24 VDC + (VCC)
Connect Brown to positive
Note:
Do not change the power supply polarity on the brown and
blue wires!
Power supply GND (-) is electrically connected to the housing
Current limit levels can be adjusted through BusLink
If the temperature drops below 0°C, all current limits will auto-
matically increase to 6 A for 24 V.
24 V ± 10% - max. 2.5 A depending on load
24 V, current limit 4 A

IO-Link is fieldbus independent and can be integrated into all
fieldbus systems worldwide.
Transmission rate: 38.4 kbaud (COM 2)
Max cable length: 15 meters

Violet
Service interface
Only BusLink can be used as service interface.
Make sure that the violet and white wires are not short-circuited

Service interface GND
Yellow
Not used
Please note that version 1.0 of IO-Link does not support data storage. Therefore, it is recommended to disable the data storage
feature on the PLC/IO-Link master.
Data storage is a recommended feature in IO-Link, which makes it easy to replace an existing device with a substitute.
