This relay is typically deployed in packaging lines, process plants, and automated machinery where timed safety responses are critical for controlled shutdown sequences.
What is Pilz PNOZ S5 C Safety Relay 24V DC 2NO 2NO (Timed) (751105)
The Pilz PNOZ S5 C Safety Relay 24V DC 2NO 2NO (Timed) (751105) is a safety control relay designed to monitor emergency stop circuits and safety devices while providing time-delayed output switching. It enables controlled machine stopping by maintaining output contacts for a defined duration after input signal removal.
In industrial automation, immediate shutdown is not always desirable. Certain processes require controlled deceleration or staged stopping to prevent mechanical stress or product loss.
The Pilz PNOZ S5 C Safety Relay is engineered for such scenarios. It integrates safety monitoring with a time-delay function, allowing machines to transition safely from operation to stop conditions.
This relay is typically integrated into:
- Emergency stop circuits
- Safety gate monitoring systems
- Two-hand control systems
Unlike standard safety relays, the timed output ensures that actuators, drives, or rotating equipment can complete safe stopping sequences before power is fully disconnected.
Applications of Pilz PNOZ S5 C Safety Relay 24V DC 2NO 2NO (Timed) (751105)
• Conveyor System Controlled Shutdown
Used in material handling systems where conveyors must decelerate gradually to avoid product pile-up or belt damage.
• Rotating Machinery Safety Circuits
Applied in mixers, centrifuges, and spindles where immediate stop may cause mechanical stress or imbalance.
• Packaging Line Synchronization
Ensures coordinated stopping of multiple stations to avoid misalignment or product jams.
• Process Plant Isolation Sequences
Used in chemical or processing plants where valves and motors must shut down in a controlled sequence.
• Automated Assembly Lines
Prevents abrupt stoppage that could damage partially assembled components.
• Robotics Safety Integration
Supports delayed stop signals in robotic cells where controlled deceleration is required.
• Fan and Blower Systems
Maintains operation briefly after shutdown signal to safely dissipate airflow or pressure.
For deeper application understanding, refer to internal guides such as industrial safety relay applications and machine safety system design principles.
Industries Using Pilz PNOZ S5 C Safety Relay 24V DC 2NO 2NO (Timed) (751105)
This relay is commonly deployed in industries where controlled stopping is essential:
- Food processing and packaging
- Automotive component manufacturing
- Pharmaceutical production lines
- Textile machinery operations
- Cement and heavy material handling plants
- Water treatment and pumping systems
Each industry uses timed safety relays differently depending on inertia, process continuity, and safety compliance requirements.
Operational Considerations
When integrating the Pilz PNOZ S5 C Safety Relay, several operational factors must be evaluated:
- Stopping Time Requirements
The delay must align with machine inertia and stopping characteristics. - Control Panel Integration
Ensure compatibility with PLCs, contactors, and motor drives. - Safety Circuit Architecture
Dual-channel wiring is often required for compliance. - Environmental Conditions
Temperature, dust, and vibration levels may influence relay performance. - Maintenance Accessibility
Placement inside panels should allow easy inspection and replacement.

FAQs
What is the function of a timed safety relay like Pilz PNOZ S5 C?
A timed safety relay allows outputs to remain active for a predefined duration after a stop signal. This enables controlled machine shutdown, preventing abrupt stops that could damage equipment or disrupt processes.
Where is Pilz PNOZ S5 C typically used?
It is commonly used in conveyor systems, rotating machinery, and process plants where controlled stopping is required. Applications often involve systems with inertia or sequential shutdown needs.
How is it different from standard safety relays?
Standard safety relays provide immediate output switching. The PNOZ S5 C includes a time-delay function, making it suitable for applications requiring gradual or staged stopping.
Can this relay be used with PLC systems?
Yes, it can be integrated with PLC-based control systems. However, it operates as an independent safety component and must be wired according to safety circuit requirements.
Does the relay support automatic reset?
Reset functionality depends on wiring configuration. Both manual and automatic reset options may be implemented based on safety requirements.
Is this relay suitable for high-load applications?
The relay itself controls circuits rather than directly handling high loads. It is typically used to trigger contactors or control elements that manage power loads.
How do I select the correct delay timing?
Timing should be based on machine stopping characteristics, inertia, and safety requirements. Engineering evaluation is recommended before selection.
Is the product readily available in India?
Availability depends on stock and sourcing cycles. Indus Megamart supports procurement across India and can assist with lead time confirmation.
