TwinSAFE Terminals for the EtherCAT® I/O system are rated for SIL 3 and conform to IEC 61508 and EN ISO 13849-1 PL e, and are certified for use throughout North America. These safety terminals for the EtherCAT I/O system use the performance of EtherCAT - the EL6900 safety PLC terminal can integrate up to 128 4-channel safety terminals (512 safety devices) and process 256 safety-relevant function blocks. The safety function blocks integrated into the EL6900 Safety PLC are configured according to each application.
The 24 Vdc digital input terminals (EL1904) and 24 Vdc digital output terminals (EL2902: 2.3 A and EL2904: 0.5 A) connect safety sensors or actuators. The TwinSAFE Terminals can be installed in any position in the terminal system and in distributed I/O systems. The EL6900 Safety PLC can also be used as a safety controller for AX5000 Servo Drives from Beckhoff, which use EtherCAT as a motion bus.
