The IO-Link T-coupler can also be used to connect an IO-Link Class B hub with galvanically separated ports to switch individual outputs or standalone valves. In this example, the output power of the four ports on the right side of the IO-Link hub (red) is independently controlled by the safety module/relay outputs. The input ports on the leſt side (blue) are galvanically separated so they can remain powered when the safety outputs are turned off. If you would like to learn more about the IO-Link solutions offered by T-coupler and other IO-Link Murrelektronik, get in touch with your local Murrelektronik representative.
