EP1918-0002 | EtherCAT Box, 8-channel digital input, 24 V DC, M12, TwinSAFE, TwinSAFE Logic

The EP1918-0002 TwinSAFE component is a digital EtherCAT Box for sensors with potential-free contacts for 24 V DC. It has eight fail-safe inputs. The signals are transmitted via FSoE to a TwinSAFE Logic-capable component and can be used there to evaluate them in terms of safety.

The EP1918-0002 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 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 EP1918-0002 can also be used as a safety controller. For example, the input signals can be prepared directly before being forwarded. 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 EP1918-0002:

• 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 EP1918-2202 can be used.

Special features EP1918-2202:

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