Mix, Match Safety Terminals

May 3, 2010
TwinSafe Terminals are designed as simple I/O safety terminals for the EtherCat I/O system. 
Rated for SIL 3 and conforming to IEC 61508 and EN ISO 13849-1 PL e, TwinSafe Terminals fully utilize the high performance of EtherCat—the EL6900 safety PLC terminal can integrate up to 128 4-channel safety terminals (512 safety devices). The 24VDC digital input terminals (EL1904) and 24VDC digital output terminals (EL2902: 2.3A and EL2904: 0.5A) are available for connecting safety sensors or actuators. Safety over EtherCat permits the integration of safety devices into a control system without requiring a stand-alone safety PLC or segregated safety network. Standard EtherCat I/O terminals can be intermixed into the same node alongside the safety terminals.Beckhoff Automation LLCwww.beckhoff.com952.890.0000
