Appendix
EL1918 and EL1918-2200 59Version: 2.0.0
8.2 Focus of certificates
The most decisive document for certified components of the TwinSAFE department is the EC type
examination certificate. The document contains both the test coverage and the regarded component and
component family.
The current certificates of all TwinSAFE components with the underlying standards and directives can be
found at https://www.beckhoff.com/en-en/support/download-finder/certificates-approvals/.
If the document refers only to the first four figures of a product (ELxxxx), the certificate is valid for all
available variants of the component (ELxxxx-abcd). This is applicable for all components like EtherCAT
Terminals, EtherCAT Boxes, EtherCAT plug-in modules and Bus Terminals.
If you regard the example EL1918 in the picture, the certificate is valid for both the EL1918 and the available
variant EL1918-2200.
