Enabling the acquisition of safety sensor signals directly on the machine or plant, the moisture- and dust-resistant EP1908 EtherCAT Box from Beckhoff brings the TwinSAFE open safety technology to IP 67 applications in harsh industrial environments. Conforming to the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849 PLe, it has eight 24V DC inputs, allowing up to eight safety sensors to be connected 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.
