EL6934 | PROFIsafe Logic Terminal with 4 digital outputs 24 V DC, 0.5 A

The Logic Terminal EL6934 can establish 15 (TwinSAFE) connections and therefore enables networks with up to 15 PROFIsafe 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. Functions such as emergency stop, safety door monitoring, 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 EL6934 Logic Terminal via PROFIBUS or PROFINET. The terminal can only be operated on PROFIBUS or PROFINET couplers. The Logic Terminal has four safe, local outputs, so that safety applications can be realised with only two components (EL1934 and EL6934). The EL6934 is suitable for applications up to SIL 3 according to IEC 61508 and EN 954 Cat. 4.

For PROFIsafe, the transmission medium is a “black channel”. Mechanisms were created for safeguarding the data against the following types of fault: repetition, loss, insertion, wrong sequence, corruption of the user data, delay, coupling of safety-relevant and non-safety-relevant data and incorrect addressing.
