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
