EL6900 | TwinSAFE PLC

TwinSAFE enables networks with up to 1,024 TwinSAFE devices. The TwinSAFE PLC can establish 128 connections to other TwinSAFE devices. Multiple TwinSAFE PLCs 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 EL6900 TwinSAFE PLC via the fieldbus. The EL6900 is suitable for applications up to SIL 3 according to IEC 61508 and DIN EN ISO 13849 PLe.
