IO-Link in general IO-Link is a manufacturer-independent point-to-point communication system used to connect sensors and actuators to an automation system.
An IO-Link system consists of an IO-Link master and several IO-Link devices. The IO-Link master represents the interface to the controller or fieldbus level and communicates with the connected IO-Link devices.
IO-Link is capable of processing switching signals of binary sensors, process values of analogue sensors and their parameters in a purely digital form based on a 24 V signal. This eliminates measuring value errors associated with the transmission and conversion of analogue signals.
IO-Link can be used to transfer several process values or parameters of a device simultaneously via one unscreened standard cable.
IO-Link is an internationally standardised fieldbus and controller independent interface.

IO Link Master field modulesThe IO-Link master is a gateway for the connection of up to 8 IO-Link devices, e.g. sensors, valves or binary input/output modules.
The master transmits machine data, process parameters and diagnostic data to the controller.
Excellent electromagnetic stability, a wide temperature range, a high protection rating and a robust housing qualify the device for use in the food industry.

IO-Link ModulesDepending on the device type, 6x2 or 10x2 in- or output can be connected to the IO-Link field module.IO-Link Module transmits the signals to any desired IO-Link master via one unscreened M12 connection cable. This eliminates the need for complex cable trees or parallel wiring and reduces costs.
Use the IO-Link Combo Module or IO-Link signal converters to connect analogue signals.
IO-Link Module requires no configuration or addressing. This simplifies the set-up.
It is possible to connect two sensors with one switching output each (using a Y splitter) or one sensor with two switching outputs to each of the module's sockets.
The modules can be used in a wide temperature range. Excellent electromagnetic stability and a robust housing qualify for reliable use in harsh industrial environments.

IO-Link signal convertersCould be used where sensors with analogue interfaces are still being used, or where no IO-Link compatible sensors do yet exist.
