The EJ1918 EtherCAT plug-in module is a TwinSAFE component with inputs for sensors with potential-free contacts for 24 V DC. The module has eight fail-safe inputs, which are transmitted via FSoE to a TwinSAFE Logic-capable component.

The EJ1918 has safety parameters to specifically adapt the functionality to the respective safety requirements. Thus, for example, test pulses can be configured with fine granularity for all eight channels in order to be able to connect as many sensors as possible with the test used.

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 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 EJ1918 can also be used as a safety controller. In the default case, the EJ1918 is a simple input module, whose input signals are transmitted via FSoE to a TwinSAFE Logic-capable component. It can also be used directly as a safety controller in order to process input signals directly in the module so as to forward only accumulated information to a TwinSAFE Logic, or a complete safety application can be implemented. The range of functions corresponds to that of the EL6910. The only difference 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.).

 

Special features EJ1918:

  • 8 safe inputs
  • integrated TwinSAFE Logic (functionality similar to the EL6910)
  • up to 128 safe connections
  • fine granular configuration of the test pulses of the individual channels

 

For applications without integrated TwinSAFE Logic, the EJ1918-2200 can be used.

 

Special features EJ1918-2200:

  • 8 safe inputs
  • fine granular configuration of the test pulses of the individual channels
  • TwinSAFE Logic not integrated
