Galvanically isolated Sensor/Actuator Hub

Galvanically isolated Sensor/Actuator Hub

IO-Link-E/A-Hub vom Typ BNI IOL-355

All-in-One I/O module with safely interruptible actuator segment

This all-in-one solution allows you to connect both sensors and actuators to just one module. At the same time you can safety turn off the actuator segment via its separately switchable safety circuit. Because the model BNI IOL-355... is divided into two galvanically isolated segments.

To safely turn off the supply voltage for the actuator segment an external safety device is required. The module is then capable of implementing safety functions up to SIL2 in accordance with EN62061.

You can operate up to eight digital in- and outputs with the module. If the IO-Link connection is interrupted, the outputs assume defined states. These states remain in effect until the IO-Link connection is restored.


  • Connect in- and output signals to just one module
  • Galvanically isolated for safe interruption of the output signals
  • Easy diagnostics using IO-Link and status LEDs
  • For harsh environments: rugged IP67 metal housing
