Omron NXSL3300 NX Series Safety CPU Unit

Description

Designed for seamless integration into high-reliability safety networks, the Omron NXSL3300 safety CPU module delivers robust, decentralized safety control functionality within the Sysmac automation platform. Operating on the high-speed NX I/O bus system, this safety controller executes safety programs independently from standard machine automation controllers, ensuring non-interrupted protection and high-speed safety loop execution.

The NXSL3300 is engineered to meet stringent global safety standards, enabling system designers to build safety control circuits that satisfy SIL 3 and PL e requirements. By combining this module with NX-series safety I/O units and an EtherCAT coupler, engineers can construct a modular, scalable, and highly flexible safety network topology using the Safety over EtherCAT (FSoE) protocol.

Features

• Achieves Safety Integrity Level 3 (SIL 3) according to IEC 61508 and Category 4, PL e according to ISO 13849-1.
• Supports up to 512 kByte of dedicated safety program memory for complex safety logic implementation.
• Integrates natively with the Omron Sysmac Studio software environment, allowing unified programming of safety, logic, and motion.
• Facilitates modular safety system expansion via the high-speed NX I/O bus interface.
• Ultra-compact 30 mm width reduces required cabinet panel space.

Applications

• Automotive assembly lines and robotic workcells requiring high-integrity safety interlocking.
• Packaging machinery and material handling systems requiring safe speed monitoring and emergency stop integration.
• Process control systems needing independent, safety-rated shutdown systems.
• Complex machinery requiring distributed safety networks over EtherCAT (FSoE).

Technical Specifications

Installation Guidelines

• Mount the unit on standard 35 mm DIN rail (IEC 60715) within an IP54 or higher industrial enclosure.
• Ensure the system power supply is completely switched off before mounting or removing the module to prevent electrical damage to the NX bus connections.
• Maintain clear ventilation channels above and below the module assembly in accordance with standard cabinet layouts.
• Use functional grounding integrated into the DIN rail track to ensure stable performance and noise immunity.
