EtherCAT plug-in module TwinSAFE Logic EJ1957
The EJ1957 EtherCAT plug-in module is a TwinSAFE component with inputs and outputs. The module has eight fail-safe inputs and four fail-safe outputs, which are controlled or processed via FSoE by a TwinSAFE Logic-capable component. The EJ1957 has safety parameters to specifically adapt the functionality to the respective safety requirements. For example, test pulses can be configured with fine granularity for all channels.
