What is Pilz PNOZ S3 Safety Relay 24V DC 2NO (750103)
Pilz PNOZ S3 Safety Relay 24V DC 2NO (750103) is a safety monitoring relay designed to supervise emergency stop circuits and safety devices in industrial machinery. It provides dual normally open (2NO) safety outputs and operates on a 24V DC supply, ensuring controlled shutdown in fault or hazard conditions.
The PNOZ S3 belongs to Pilz’s modular safety relay series, commonly used in discrete machine safety applications. It monitors input signals from safety devices such as emergency stop push buttons, safety interlock switches, and guard doors.
When a fault condition is detected—such as a circuit interruption or unsafe machine state—the relay ensures immediate disconnection of hazardous motion by switching its safety outputs. The 2NO output configuration is typically used for enabling or interrupting control circuits connected to contactors, drives, or PLC safety inputs.
Its compact design allows integration into control panels where space constraints and wiring simplicity are important considerations.
Applications of Pilz PNOZ S3 Safety Relay 24V DC 2NO (750103)
• Emergency Stop Monitoring in Assembly Lines
Used in automotive or electronics assembly stations where operators require immediate shutdown capability during abnormal conditions.
• Packaging Machine Safety Circuits
Ensures safe stoppage of conveyor-driven packaging machines during jam conditions or manual intervention.
• Material Handling Equipment Protection
Applied in conveyor belts and lifting systems to disconnect drive circuits when safety guards are opened.
• Robotic Work Cell Safety Integration
Acts as an interface between safety devices and robot controllers to prevent unintended movement during maintenance.
• Food Processing Equipment Isolation
Supports hygienic processing lines where frequent operator interaction requires reliable safety interruption.
• Standalone Machine Safety Panels
Suitable for OEM-built machines where independent safety circuits are preferred over fully integrated PLC-based safety systems.

Each industry uses the relay differently depending on machine complexity, operator interaction frequency, and safety compliance requirements.
Operational Considerations
When integrating the Pilz PNOZ S3 Safety Relay 24V DC 2NO (750103), the following factors should be evaluated:
• Compatibility with Control Systems
Ensure proper interfacing with contactors, PLC inputs, or motor drives.
• Safety Circuit Design
Appropriate redundancy and feedback loops should be implemented based on risk assessment.
• Panel Space and Layout
Compact relay design supports dense panel configurations, but wiring accessibility should be considered.
• Environmental Conditions
Suitable for standard industrial environments; additional protection may be required in high humidity or dusty areas.
• Compliance Requirements
Installation must align with applicable safety standards defined by project consultants or regulatory bodies.
Customization Options
As a standard safety relay module, the Pilz PNOZ S3 Safety Relay 24V DC 2NO (750103) does not offer customization in its internal configuration.
However, system-level customization can be achieved through:
• External wiring configurations
• Integration with different safety devices
• Panel design adaptations
• Combination with expansion modules or additional relays
Indus Megamart supports buyers in selecting compatible configurations based on project needs.
