BECKHOFF EtherCAT Terminal, 8-channel digital input, 24 V DC, TwinSAFE, TwinSAFE Logic - EL1918
The EtherCAT terminal has eight fail-safe inputs, which are transmitted via FSoE to a TwinSAFE Logic-capable component. The EL1918 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 types of sensors as possible.

Information About EL1918
The safety parameters are not stored directly on the component, but are transmitted to the input terminal 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 of the EL1918 is the integration of the functionality of the EL6910 TwinSAFE Logic. The EL1918 can also be used as a safety controller at any time. In the default case, the EL1918 is a simple input terminal, whose input signals are transmitted via FSoE to a TwinSAFE Logic-capable component. It can be used directly as a safety controller in order to process input signals directly in the terminal so as to forward only accumulated information to a TwinSAFE Logic, or a complete safety application can be implemented on the EL1918. 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 EL1918:
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 EL1918-2200 can be used.
