Safety in system: Protection vor man and machine INSTALLATION SYSTEMS FOR SAFE SERIES CONNECTION

Heinz and Philip Schmersal, Managing Directors of the Schmersal Group Optimum safety solutions for your production processes Based on the world‘s largest programme of safety switchgear, the Schmersal Group develops safety systems and safety solutions tailored to individual requirements. After all, it is not just about safeguarding individual machines but complex plant systems. Having flexibility in production is becoming an increasingly important factor in today‘s production: The batch sizes are becoming smaller and there needs to be a fast and simple way to adapt the machines to changing products...

DESCRIPTION OF SAFETY INSTALLATION SYSTEMS INTRODUCTION Schmersal safety installation systems Schmersal safety installation systems are installation aids for fast, simple and thereby low cost wiring of safety switchgear in series. The solutions are divided into two areas: passive distributors and fieldboxes for the connection of electronic safety switchgear as well as active input expander modules for the connection of safety switches and safety sensors with contact outputs or as electronic versions. The passive distributors for installation in switching cabinets or terminal boxes and the fieldboxes...

Schmersal SD-Interface The "Series Diagnostic" interface is used for transferring non-safe data where electronic safety switchgear is connected in series. Safety sensors and interlocks that feature the SD interface can transfer extensive diagnostic data from the individual devices with series-wiring via the SD gateway and a field bus to a control system. Interlocks with series-wiring can also be locked or unlocked individually via the SD interface. There are additional control functions on some interlocks from Schmersal, such as the latching force adjustment on the MZM 100-SD. A mixed installation...
