EL1918 | 8-channel digital input terminal, TwinSAFE, 24 V DC, TwinSAFE Logic

The EL1918 TwinSAFE EtherCAT Terminal is a digital input terminal for sensors with potential-free contacts for 24 V DC. The EtherCAT Terminal has eight fail-safe inputs. The EL1918 integrates a programmable TwinSAFE Logic enabling the implementation of safety applications directly in the terminal. Depending on the application, the safety-oriented information can be pre-processed directly in the terminal so that the central TwinSAFE Logic need only process the information that is aggregated.
