Omron NX-SL3300 NX Series Safety Controller 32 Safety Master Connections

Omron NX-SL3300 is a safety CPU unit for the NX series I/O system. Part of the Sysmac automation platform, it manages safety logic (e.g., emergency stops, light curtains) over EtherCAT using FSoE (FailSafe over EtherCAT) protocol. Up to 32 safety master connections and 256 safety I/O points. Compliant with EN ISO 13849-1 (PLe / Category 4) and IEC 61508 (SIL3). Configured and programmed using Sysmac Studio automation software. Supports stand‑alone system operation with an EtherNet/IP coupler (NX‑EIC202) as well as integration into an EtherCAT network via an EtherCAT Coupler Unit (NX‑ECC20[]).

Applications:

• Emergency stop circuit and guard door interlock monitoring
