Request a QuoteA safety relay module evaluates the signals from interlocks, light curtains and emergency stops, and it is the component that actually decides whether the machine is allowed to run. Its function determines the achievable performance level of the whole safety function.
Selection follows the safety function: the number and type of inputs, whether stop category 0 or 1 is required, and the required PL or SIL. Safety gateways extend the same logic onto a network for diagnostics.
Send the Schmersal type designation and the function it performs, and we will quote the direct replacement or the current successor.
Applications
- Interlock and E-stop evaluation
- Light curtain monitoring
- Stop category 0 and 1 circuits
- Safety network gateways
Schmersal Safety Relays: Common Questions
By the function rather than the catalog: the number and type of inputs, whether stop category 0 or 1 is required, and the performance level or SIL the assessment calls for.
When removing power immediately is itself hazardous, for example on a machine with high inertia. Category 1 brings it to a controlled stop first, then removes power.
Often, but it depends on the input types and the rating you need. Send what the module has to watch and we will specify it.
They put the same evaluation on a network so diagnostics reach the controller, which turns a tripped guard from a hunt into a message.
