EL6904 | TwinSAFE Logic Terminal

TwinSAFE enables networks with up to 1024 TwinSAFE devices. Multiple logic terminals are cascadable within a network. The EtherCAT Terminal features certified safety function blocks, which are configured according to the application to be realised. Safety functions such as emergency stop, safety door monitoring, two-hand control, etc. can thus easily be selected and linked. All blocks can be freely connected among each other and are complemented by operators such as AND, OR, etc. The required functions are configured via the TwinCAT System Manager and loaded into the EL6904 Logic Terminal via the fieldbus. The TwinSAFE Logic Terminal has four safe, local outputs, so that safety applications can be realised with only two components (EL1904 and EL6904). The EL6904 is suitable for applications up to SIL 3 according to IEC 61508 and EN 954 Cat. 4.
