Meeting machine safety requirements and improving commissioning is a challenging task for maintenance teams and system integrators.  The NX-SL3 offers a cost-effective safety controller with a modular design making it easy to adapt to a variety of machine types and sizes. For retrofit projects, it offers a direct connection to any PLC using an EtherNet/IP coupler. For systems requiring remote I/O, the NX-SL3 can be combined with an EtherCAT coupler to enable Functional Safety over EtherCAT(FSoE), making the project seamless to operate and maintain.  The IDE of Sysmac Studio simplifies the safety configuration, programming, and maintenance, thanks to its unique features such as automatic programming, simple automatic test, and safety function verification.
