CHIDA Beckhoff EL1918 EtherCAT Terminal 8-channel Digital Input 24 V DC Module

The TwinSAFE terminal module EL1918 is a digital input terminal module, suitable for 24 V DC sensors with passive contacts. The EtherCAT terminal module has 8 safety inputs, and the signals can be transmitted to the TwinSAFE safety logic module via FSoE.
EL1918 is equipped with safety parameters that can be adjusted according to specific safety requirements. For instance, the test pulses for all 8 channels can be set differently to enable the connection of various types of sensors as much as possible.
The safety parameters are not directly stored on the components, but are transmitted to the input terminal module through the TwinSAFE safety logic module when the safety application is started. This simplifies the maintenance procedures, as in this case, the components can simply be replaced. When the safety application restarts, the safety-related parameters will be transmitted to the new components.
Another highlight of EL1918 is that it integrates the functions of the EL6910 TwinSAFE logic terminal module. EL1918 can also be used as a safety controller at any time. By default, EL1918 is a simple input terminal module, and its input signals are transmitted to the TwinSAFE safety logic module through FSoE. It can be directly used as a safety controller to directly process the input signals in the terminal module, thereby only forwarding the accumulated information to the TwinSAFE logic. It can also implement a complete safety application on EL1918. Functionally, it is similar to EL6910. The only difference is that the number of safety connections is limited to 128. Additionally, it has all the advantages of the new generation of safety controllers (refer to EL6910 customization, incremental download, analog value processing, etc.).
