Omron NX-SL3300 Safety CPU Unit PLC Module System

The Omron NX-SL3300 Safety CPU Unit is a safety controller module that executes safety logic, monitors inputs, and drives safe outputs within Omron NX-series PLC systems. It supports distributed safety I/O modules and communicates over EtherCAT with Safety over EtherCAT (FSoE) for networked safety control, while programming is performed in Sysmac Studio and it includes integrated safety program memory. Mounted on a DIN rail as part of the NX-series modular system, this unit is compatible with Omron NX, NJ, NX1, and NX7 controllers, and is specified for an operating temperature range of 0°C to 55°C with a safety level of SIL3 / PLe depending on system configuration. Common applications include machine guarding, emergency stop systems, robotics, and production lines where integrated safety logic processing and reliable safety standard compliance are required. Common replacements for this unit include NX-SL3500, NX-SL5500, and G9SP-N20S.
