Minneapolis, MN


announced new

AS-Interface (AS-i) safety monitors

that are manufactured by

Bihl + Wiedemann

and distributed by Turck. The monitors are required for controlling power availability for machine safety (emergency stop) systems using

AS-i Safety at Work


Monitors provide a graphical user interface (GUI) for commissioning and field diagnosis of the safety system, along with the capability to link multiple Safety at Work circuits, to permit larger, more complex safety systems to be handled via AS-i.

Monitor configuration is stored on a removable memory card, which simplifies transfer of the configuration to a new unit.

Offered as stand-alone units for use with standard AS-i masters and gateways, or as a package with an integrated


gateway, monitors can be used as AS-i 2.0, 2.1, and 3.0 slaves, making them accessible to all available AS-i masters.

Turck is the authorized supplier of all Bihl + Wiedemann AS-i products in North America.
