The SCR DI system is ideal for smaller machines, for larger machines, the SCR P is recommended. Where several safety relays were previously often required, the programmable SCR P is used alone and implements all safety functions. In addition, the two independent enabling paths allow switching off different zones of larger machines. The SCR P monitors up to 5 safety circuits, each with the maximum safety level of PL e. On the one hand, costs for hardware can be saved. On the other hand, wiring effort required by the customer is considerably lower, which results in considerable time savings. Thanks to the intuitively operated software, the user can easily program the relay. Providing diagnostic data also plays an important role in the SCR P. Those are available to the user via a selectable Ethernet protocol.
