Turn off fluid drives safely

All-in-one solution for connecting sensors and actuators

Turn off fluid drives safely

Our galvanically isolated sensor/actuator hub provides safety on pneumatic and hydraulic axes and actuators. This all-in-one solution allows you to connect both sensors and actuators to just one module. The sensor segment provides the position feedback.

At the same time, you can safely turn off the actuator segment using its separately switchable safety circuit, since the IO-Link I/O hub is divided into two galvanically isolated segments. To safely interrupt the supply voltage to the actuator segment, you need an external safety device. Then you can implement safety functions up to SIL2 in accordance with EN62061. Also reassuring: the rugged IP67 metal housing is designed even for the harshest surroundings. Diagnostics are provided by IO-Link and several status LEDs. You can also reliably monitor the signal quality using IO-Link. Up to digital in- and outputs can be controlled with the module. If the IO-Link connection is interrupted, the outputs assume predefined states which are maintained until the IO-Link connection is restored. Because of this unambiguous machine status, you can continue to produce without a reference move and save valuable time once the connection is made again. The SmartLight stack light incorporated into the IO-Link network visualizes the current status of the cylinder, gripper or slide.
