NX-series Safety Control Units
NX-SL/SI/SO
Integration of Safety into Machine
Automation Enables Simple,
Flexible System Configuration.
• EN ISO13849-1 (PLe/Safety Category4), IEC 61508 (SIL3) certified.
• One connection using Safety over EtherCAT (FSoE)
enables flexible configuration by mixing the Safety Units with standard
NX I/O.
• Hardware and safety circuits can be configured using the Sysmac
Studio (Ver. 1.07)
* 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.
Features
• Integrated safety into machine automation possible by connecting with the NX-series EtherCAT Coupler.
• The Safety CPU Unit controls up to 128 Safety I/O Units.
• 4 or 8 points per Safety Input Unit. The 4-point Safety Input Unit can be directly connected with OMRON Non-contact Switches and Singlebeam
Sensors.
• 2 or 4 points per Safety Output Unit. The 2-point Safety Output Unit is characterized by large output breaking current of 2.0 A.
• The Safety Units can be freely allocated in any combination with standard NX I/O.
• Compliant with IEC61131-3
• Safety programs can be standardized and reused efficiently by using POUs for design and operation.
