KL6224 | IO-Link terminal

In the standard setting, the KL6224 functions as a 4-channel input terminal, 24 V DC, which communicates with connected IO-Link devices, parameterises them and, if necessary, changes their operating mode.

Integration into the HD housing with 16 connection points enables each IO-Link device to be operated in 3-wire connection mode. The direct plug-in technique enables toolless construction.

Additional 24 V and 0 V connection points can be realised via the KL918x potential distributor terminal.
