The technology of the IO-Link K20 modules extends the IO-Link beyond a pure point-to-point connection and creates distributed structures. It must be considered that the cable length of an IO-Link connection restricts the distance between an IO-Link module and the master to max. 20 m.
For the connection of binary sensors, the IO-Link K20 modules are available in versions with 4 or 8 digital inputs. The sensor connection is realized via M8 or M12 connections and connection to the IO-Link master is established via a standard M12 connection line.
