The EP1957-0022 TwinSAFE component provides safe digital outputs in a module with IP67 protection (four outputs for 24 V DC actuators up to 0.5 A). It also has eight fail-safe inputs for sensors with potential-free contacts for 24 V DC. The signals are connected via M12 screw connectors. The sensors are powered by the load voltage UP.

The EP1957-0022 has safety parameters to specifically adapt the functionality to the respective safety requirements (e.g. testing of the individual channels).

The safety parameters are not stored directly on the component, but are transmitted to the input component via a TwinSAFE Logic-capable component when the safety application is started. This simplifies service procedures, because in this case the component can simply be replaced. The safety-relevant parameters are transferred to the new component when the safety application is restarted.

A further highlight is the integration of the functionality of the EL6910 TwinSAFE Logic. The EP1957-0022 can also be used as a safety controller. With the help of the locally available inputs and outputs, a complete safety application can be realized directly on the component. The range of functions corresponds to that of the EL6910. The only difference at this point is the limitation of the number of possible safe connections to 128. Apart from that, all the advantages of the new generation of safety controllers can be used (see EL6910 customizing, incremental download, analog value processing, etc.).

In addition, a safety application based on local inputs and outputs can also be implemented "stand-alone" without a connection to EtherCAT.

 

Special features EP1957-0022:

  • 8 safe inputs
  • 4 safe outputs
  • integrated TwinSAFE Logic (functionality similar to the EL6910)
  • up to 128 safe connections
  • complete safety loop can be realized directly on the component
  • stand-alone operation (without EtherCAT connection)
  • Standard outputs can be activated with integrated ANDing with a safe output signal.

 

For applications without integrated TwinSAFE Logic, the EP1957-2222 can be used.

 

Special features EP1957-2222:

  • 8 safe inputs
  • 4 safe outputs
  • Standard outputs can be activated with integrated ANDing with a safe output signal.
  • TwinSAFE Logic not integrated
