Pilz PNOZ S5 Safety Relay, Time Monitoring

Product Dimensions：

The Pilz PNOZ s5 is an advanced, electronic Safety Timer Relay from the PNOZsigma compact series. It is designed to provide safe delay-on-de-energization or delay-on-energization functions, making it a critical component for controlled stopping sequences in machinery safety.

Product Detailed Description

The PNOZ s5 combines traditional safety relay functionality with an adjustable electronic timer. It is primarily used to monitor safety circuits (such as E-stops, safety gates, or light curtains) and safely remove power to actuators after a user-defined delay. This delay allows heavy machinery or rotating parts to come to a complete, safe stop before an operator can gain access.

Technical Parameters

Product Advantages

• Ultra-Compact Design: At only 22.5 mm wide, it packs multi-functional timed safety outputs into a minimal footprint, saving valuable space on the DIN rail.
• Precise Rotary Settings: The front-panel rotary switches allow quick, clear, and repeatable adjustment of the time delay without needing software.
• Rapid Diagnostics: Features integrated LED indicators for Power, Input status, Reset status, and individual Output channels, streamlining troubleshooting.
• Expansion Capabilities: Can be seamlessly connected to PNOZsigma contact expansion modules (like the PNOZ s7) via a base connector, expanding the number of safety contacts without extra wiring.

Important Considerations & Precautions

• Time Setting Lock: After configuring the desired time delay via the rotary switches, ensure the transparent front cover is closed and sealed to prevent unauthorized or accidental modifications.
• Reset Configuration: The module can be configured for Automatic or Manual/Monitored reset. Choosing the wrong mode can lead to unexpected machine restarts, posing a safety hazard.
• Actuator Disconnection: Ensure that the time-delayed safety contacts are correctly wired to the specific braking mechanism or safe torque off (STO) inputs of your motor drives.
• Supply Tolerance: The unit operates on 24 V DC. Ensure the power supply is regulated, as voltage fluctuations outside the standard operating window (\pm 20\%) can trigger the internal safety protection and fault the device.

Product Applications

The PNOZ s5 is heavily utilized in applications requiring a managed stop sequence:

• High-Inertia Machinery: Controlling safety gates on industrial shredders, centrifuges, and large fans where the blades continue to spin after power is cut.
• Robotic Work Cells: Implementing a delayed stop to allow an industrial robot arm to complete a cycle or reach a home/safe position before entering a safe state.
• Packaging Machines: Managing interlocking guard systems where a brief pause is required for pneumatic or mechanical assemblies to depressurize or settle.
• Automated Material Handling: Safeguarding high-speed transfer lines and sorting systems.
