Flexible safety concepts for injection moulding machines
Automated injection moulding machines have particularly high demands on safety technology. A performance level of PLe and highly coded safety sensors or switches are the basic prerequisites for such a safety concept. Injection moulding machine manufacturers use standardized EUROMAP interfaces between injection moulding machines and external safety devices. The EUROMAP 73 and EUROMAP 78 are often used here.
The EUROMAP 73 driven by DIN EN 201 requires three NO contacts and three NC contacts from the safety devices to integrate the injection moulding machine. On the other hand, the newer EUROMAP 78 uses intrinsically safe OSSD signals (Output Switching Signal Device).
With the Safety Simplifier, SSP offers a complete safety solution with an integrated EUROMAP 73 or EUROMAP 78 interface as a plug & play variant. Thanks to the safety-oriented wireless communication (PLe), the system is extremely flexible and there is no cabling effort for the user.
