Pilz – Safe automation, automation technology - Pilz INT

The PNOZsigma series often features a modular design, allowing users to customize the relay configuration based on the specific safety requirements of their applications. Modules can be added or removed as needed. NOZsigma relays are versatile and can be used in various safety applications, such as emergency stop, light barriers, safety gates, and more. They are suitable for applications up to SIL 3 (Safety Integrity Level 3) according to EN 62061 or PL e (Performance Level e) according to ISO 13849. These safety relays typically offer diagnostic functions that provide information about the current status of the safety system. This can help in troubleshooting and maintenance.

PNOZsigma relays can be integrated into larger automation systems, working in conjunction with programmable logic controllers (PLCs) and other control devices. These relays monitor safety inputs, such as emergency stop buttons or safety switches, and ensure that the machinery or process comes to a safe state when necessary. PNOZsigma relays often have reset functions to allow the system to resume operation after a safety event has been resolved. The reset may involve a manual action or an automated process depending on the application. The PNOZsigma series is designed to comply with relevant safety standards such as EN ISO 13849 and EN 62061, providing a framework for the design and validation of safety-related control systems.

When using safety relays like PNOZsigma in an application, it’s crucial to adhere to the manufacturer’s guidelines and standards applicable to your industry. Additionally, regular maintenance and testing of safety systems are essential to ensure continued reliability and compliance with safety regulations.
