SafeBox safety control units are modularly constructed so that up to eight components can be connected to a single control unit. Depending upon application requirements, existing solutions are expanded by connecting additional function modules via DIP switches. These function modules offer functions such as start/restart interlock, muting, override, or emergency stop.

The SafeBox is suitable as a controller for SLA-type thru-beam sensors or as a connection device for protective equipment such as safety light curtains, safety switches, or emergency stop buttons. Safety requirements up to performance level e, Cat. 4, and SIL 3 are met.

Configuration and position of the channels are recognized autonomously—SafeBox safety control units require no additional software programming. This significantly simplifies installation of these safety sensors.
