IO-Link range with repeaters

February 2021 Fieldbus & Industrial Networking

In many installations, sensors have to be installed far away from their network connection point. Since IO-Link only has a guaranteed range of 20 m, high additional costs can incur if longer ranges are required. Using the IO-Link repeater E30444, this distance can be increased, which reduces costs significantly. To do so, the IO-Link repeaters are simply installed in series into the cable, depending on the application and the requested range.

The maximum range depends on the type of transmission, the cable cross section and the current consumption of the connected device. The IO-Link repeater is transparent to masters and functions manufacturer-independently on all certified IO-Link masters. SIO operation is not possible with the IO-Link repeater. The process data can be delayed by up to one cycle, with acyclic data delayed by up to two cycles per repeater. A summary of features includes:

• IO-Link range increased up to 240 m.

• Series connection of 3 repeaters possible.

• Perfectly suited for use in the food industry.

• Easy setup thanks to plug and play, no configuration necessary.

• Transparent to all certified IO-Link masters.
