The right solution for every application

The Schmersal group is launching new installation aids for securing complexing machine systems which allow quick and simple wiring of safety switchgear in series: the Schmersal safety installation systems. The series connection significantly reduces the wiring involved. A particular benefit of this installation system is that different electronic safety switchgear systems, such as sensors and interlocks, can be mixed and connected in the relevant application. With larger systems, different machine areas often need to be secured using different safety switches. At the same time, the new system offers cost-optimised options for applications exclusively using electronic safety switchgear.

The safety installation systems also allow individual diagnosis of the safety switchgear connected. This means the operator can clearly identify which switch in the series has triggered a signal.  Therefore, any errors can be fixed quickly and machine downtime can be avoid. The safety installation systems from Schmersal thus increase machine availability.

Aside from standard I/O devices, an option also exists to connect safety sensors and interlocks with serial diagnosis. Comprehensive diagnostic data can be transferred to a control system via the SD gateway by means of series diagnostics.
