NX-SI / SO

Safety I/O Unit

NX-SI / SO

4 or 8 points per Safety Input Unit,2 or 4 points per Safety Output Unit.

EN ISO13849-1 (PLe/Safety Category4), IEC 61508 (SIL3) certified.

One connection using Safety over EtherCAT (FSoE) * protocol enables flexible configuration by mixing the Safety Units with standard NX I/O.

4 or 8 points per Safety Input Unit, 2 or 4 points per Safety Output Unit. Characterized by large output breaking current of 2.0 A.

* Safety over EtherCAT (FsoE): The open protocol Safety over EtherCAT (abbreviated with FSoE "FailSafe over
    EtherCAT") defines a safety related communication layer for EtherCAT. Safety over EtherCAT meets the requirements
    of IEC 61508 SIL 3 and enables the transfer of safe and standard information on the same communication system
    without limitations with regard to transfer speed and cycle time.
