The Pilz PNOZ X2.1C 24VAC/DC 2N/O – 774305 is a versatile and compact safety relay developed for reliable monitoring of emergency stop devices, safety gates, and protective covers in industrial environments. Part of the proven PNOZ X relay series, this model delivers efficient energy usage, flexible supply compatibility, and robust safety functionality to safeguard operators and machinery.

Designed for 24 V AC or DC supply, the PNOZ X2.1C provides exceptional integration flexibility. This dual supply compatibility makes it suitable for both legacy AC-based systems and modern DC-controlled architectures, reducing complexity in retrofits and simplifying implementation in new installations. Its efficient energy profile, requiring only 4.5 VA in AC operation or 2 W in DC mode, ensures cost-effective performance in continuous use.

The relay is equipped with two safety inputs, enabling dual-channel monitoring. This redundancy ensures faults such as short circuits, cross faults, or wiring errors are reliably detected, significantly increasing system integrity. The dual-channel design guarantees that safety functions are triggered only when both channels are activated correctly, reducing the likelihood of dangerous undetected failures.

For output switching, the PNOZ X2.1C offers two normally open (N/O) safety contacts. These outputs are designed to provide secure enabling signals to actuators, motors, or contactors, ensuring hazardous movements are stopped immediately in the event of an emergency or fault condition. The straightforward output configuration makes it simple to integrate into existing systems while providing dependable functionality.

Built with durability in mind, the PNOZ X2.1C is designed for control cabinet installation, with a compact form factor that conserves valuable panel space. Its rugged housing and high-quality construction ensure a long service life, even in demanding industrial environments where frequent actuation and continuous operation are common.

The PNOZ X2.1C is ideal for use in industries such as packaging, material handling, robotics, food processing, and general manufacturing, where protecting operators and maintaining machine safety compliance are critical. By reliably monitoring protective devices and ensuring controlled machine shutdown when necessary, it helps reduce accidents, protect equipment, and support productivity.

As part of the Pilz PNOZ X family, the X2.1C benefits from decades of safety engineering expertise and compliance with international safety standards. It integrates seamlessly with other Pilz products, offering a scalable solution for machine safety requirements.

In summary, the Pilz PNOZ X2.1C 24VAC/DC 2N/O – 774305 is a compact, energy-efficient safety relay that combines flexible supply compatibility, dual-channel safety monitoring, and reliable switching outputs. It is a trusted and practical choice for safeguarding modern industrial equipment and ensuring operator protection.
