TwinSAFE, machine safety simplified in harsh industrial environments
The TwinSAFE open safety technology is now available to the IP 67 world with the new EP1908 EtherCAT Box. The EtherCAT Box has eight 24V DC inputs and enables the acquisition of safety sensor signals directly on the machine or plant. The EP1908 conforms to the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849 PLe.
The TwinSAFE safety solution is already integrated into the Beckhoff IP 20 systems – the Bus Terminals and EtherCAT Terminals. That is now extended to the IP 67 system with the moisture- and dust-resistant EP1908 EtherCAT Box. Up to eight safety sensors can be connected to a module via M12 plug connectors.
The necessary logical links of the acquired signals are carried out by the IP 20 TwinSAFE logic terminal, which is the core of the system. The safety application is configured or programmed in TwinCAT automation software. It is subsequently loaded via the bus system to a TwinSAFE logic terminal of type KL6904 (Bus Terminal) or EL6900 (EtherCAT Terminal). All safety devices in the plant communicate with this logic terminal. The certified safety function blocks of the TwinSAFE logic terminals allow the simple and inexpensive implementation of all safety tasks.
