Fast, safe and wear-free switching

Evaluation units with sold-state components are becoming increasingly established in safety applications, as a considerably higher number of starting operations and electrical life of the devices is achieved with permanent functional checks and consistently wear-free work. The compact and light devices also permit series connection or normal operating switching, e. g. through a PLC.

If several enabling circuits or floating enabling circuits are required in one application, the units can be expanded with expansion units from the 3SK121. or 3TK2830 series.

3TK2845 multifunction devices

Usual combinations of safety applications, such as EMERGENCY-STOP and protective door monitoring, could only be realized in the past by using several individual safety relays. 3TK2845 unites several functions in one device. Two solid-state and two relay enabling circuits ensure safe disconnection – in just a few actions, quickly and cheaply.
