PILZ PSS1 PS 24

Product Details

The PSS1 PS 24 is a 24 VDC power supply with integral protection and monitoring circuits. It's designed to reliably supply power to Pilz safety controllers and associated modules. An internal test algorithm monitors the module's correct function, indicated by an LED. It also typically includes an exchangeable buffer battery to supply non-volatile memories and the real-time clock.

Product Advantages

• Integral Protection and Monitoring: The module incorporates built-in circuits for protection and continuous monitoring, ensuring the reliability and safety of the connected system.

• Designed for Safety Systems: It's specifically engineered to work seamlessly with Pilz's PSS 3000 and PSS 3100 safety control systems, contributing to the overall safety integrity of the machinery or plant.

• Reliable Power Supply: Provides stable and regulated 24 VDC power, essential for the consistent operation of critical safety functions.

• Easy Connection: Features screw connectors for straightforward and secure wiring.

• Type-Approved: Failsafe modules from Pilz, including this power supply, often have specific type approvals, indicating their compliance with relevant safety standards.

Precautions

• Installation: The module should be installed vertically on a module rack to ensure proper cooling and operation within its specified temperature range.

• Environmental Conditions: Ensure the operating environment stays within the specified ambient temperature and humidity to prevent damage or malfunction. Condensation is not permitted.

• Power Requirements: Verify that the external supply voltage meets the specified 24 VDC with the allowed tolerance range.

• Battery Life: The internal buffer battery (if present) has a limited service life (approx. 2 years) and should be checked and replaced as per manufacturer recommendations to maintain the integrity of non-volatile memories and the real-time clock.

• Cybersecurity: When integrating into larger systems, consider implementing an overall industrial security concept to protect against cyber threats, as advised for Pilz products.

• Manufacturer Information: Always refer to the official Pilz operating manual for detailed safety instructions, installation guidelines, and troubleshooting information.
