The Pilz PNOZ X2.8P 24VACDC 3N/O 1N/C (777301) is a versatile and highly reliable safety relay developed for use in machinery and plant engineering applications where functional safety and operator protection are essential. As part of the trusted Pilz PNOZ X series, this relay combines straightforward design with proven dependability, delivering cost-effective and robust safety monitoring for critical machine operations.
One of the defining characteristics of the PNOZ X2.8P is its dual-channel input monitoring capability. This design feature allows for redundant monitoring of emergency stop devices, safety gates, or light curtains, ensuring that even if one input fails, the safety function remains uncompromised. This redundancy not only supports compliance with modern safety standards but also enhances operator confidence in high-risk industrial environments.
The relay provides three normally open (N/O) safety contacts and one normally closed (N/C) auxiliary contact, offering flexible integration into control circuits. The N/O outputs can be used for direct actuation of safety-relevant actuators such as contactors, while the N/C contact can serve as a signalling function for system monitoring or fault indication. This configuration makes the relay suitable for applications requiring simultaneous safety output and feedback reporting.
Engineered for reliability, the PNOZ X2.8P is designed to handle AC and DC supply voltages at 24 V, giving it wide application compatibility in modern machine control systems. Its contacts are rated for up to 240 V AC at 6 A, in line with EN 60947-4-1 standards, enabling robust switching performance across various load types. This ensures dependable long-term operation even under frequent switching cycles, which is typical in automated production environments.
Compact in size yet powerful in function, the PNOZ X2.8P is easy to install within control cabinets. Its modular housing design supports straightforward mounting on DIN rails and allows seamless integration with other Pilz safety components. As part of the Pilz portfolio, it adheres to rigorous quality standards, making it a trusted choice for industries such as automotive, packaging, material handling, and general machinery.
In summary, the Pilz PNOZ X2.8P (777301) safety relay provides a dependable and flexible solution for safeguarding people and equipment. With dual-channel input monitoring, versatile contact options, and compliance with international safety standards, it ensures reliable machine protection while supporting streamlined integration into existing control systems.
