Bus Terminal TwinSAFE Logic KL6904
TwinSAFE enables networks with up to 1,024 TwinSAFE devices. The KL6904 TwinSAFE logic Bus Terminal can establish 15 connections (TwinSAFE connection). Multiple logic terminals are cascadable within a network. The Bus Terminal features certified safety function blocks, which are configured according to the application to be realized. Functions such as emergency stop, safety door monitoring etc. can thus easily be selected and linked. All function 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 KL6904 logic terminal via the fieldbus. The TwinSAFE logic terminal has four safe, local outputs, so that safety applications can be realized with only two components (KL1904 and KL6904).
