EtherCAT Terminal TwinSAFE Logic EL2911

The EL2911 TwinSAFE component is a potential supply terminal and enables the setup of TwinSAFE groups with a safe power supply (24 V DC, up to 10 A). If the TwinSAFE terminal detects an error, it switches to the safe state (fail-safe). Safe potential groups can be created within a terminal segment using the EL2911. Thus, interference-free standard terminals can be safely switched off and integrated into the safety application. In addition, the EL2911 has four safe inputs. The safety-relevant data are exchanged via FSoE with a TwinSAFE Logic-capable component. 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 in this case 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 EL2911 is the integration of the functionality of the EL6910 TwinSAFE Logic. The EL2911 can thus also be used as a safety controller at any time. With the help of the locally available inputs and outputs, a complete safety application can thus be realized directly on the terminal. The range of functions corresponds to that of the EL6910. The only difference at this point 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 EL2911: 4 safe inputs 1 safe output with 10 A integrated TwinSAFE Logic (functionality similar to the EL6910) up to 128 safe connections complete safety loop can be realized directly on the component safe potential groups for the safe shutdown of interference-free standard components fine granular configuration of the test pulses of the individual input channels Standard outputs can be activated with integrated ANDing with a safe output signal For applications without integrated TwinSAFE Logic, the EL2911-2200 can be used.
