Schmersal Safety Field Box system

The Safety Field Box system with universal device interface from Schmersal features an 8-pole M12 connector and is compatible with a wide range of safety devices including electronic and electromechanical safety interlocks, switches, sensors, light curtains and operation panels. Safety devices from other vendors can also be connected easily with an adapter, further adding to the available device types.

The Safety Field Bus solution has the advantage of being simple and flexible, with inbuilt signal diagnostics, leading to lower installation and commissioning costs. The flexibility is due to the ability to create a decentralised and free topology with simple connection of power, with plug-and-play device installation with up to eight devices per SFB.

The configurable safety field box allows safety switchgear devices to be connected in the field and freely interlinked on a decentralised basis. Straightforward connection allows for quick and failsafe installation.

The power supply to the field box is via an M12 power connector with a current carrying capacity of 10 A. The cable section of 3 mm² allows for simple installation of the field boxes in series with a single central power supply.

Profinet and PROFISafe devices can be connected in up to PL e/Category 4/SIL 3 applications. An integrated web interface is available for displaying status and diagnostic data.
