Highly scalable, highly modular: safe automation with TwinSAFE

The EL1918 TwinSAFE component is a digital input terminal for sensors with potential-free contacts for 24 V DC. The EtherCAT terminal has eight fail-safe inputs, which are transmitted via FSoE to a TwinSAFE Logic-capable component.

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 EL2912 TwinSAFE component is a digital output terminal. It has two fail-safe outputs with up to 2 A. The outputs are controlled by a TwinSAFE Logic-capable component via FSoE.

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 EP1957-0022 TwinSAFE component provides safe digital outputs in a module with IP67 protection (four outputs for 24 V DC actuators up to 0.5 A). It also has eight fail-safe inputs for sensors with potential-free contacts for 24 V DC. The signals are connected via M12 screw connectors. The sensors are powered by the load voltage UP.
