The Pilz PNOZ X2.8P 24–240VAC/DC 3N/O 1N/C (Part No. 777302) is a versatile and high-performance safety relay designed to monitor critical safety functions and ensure hazardous machine operations are reliably shut down when unsafe conditions arise. Part of the trusted PNOZ X series, it is engineered to deliver simplicity, flexibility, and compliance with international safety standards, making it suitable for a wide range of industries and machine types.

A standout feature of the PNOZ X2.8P is its broad supply voltage range of 24–240 V AC/DC, which allows it to be used globally across varied electrical infrastructures without the need for additional power conversion. This wide compatibility makes it especially useful for machine builders and system integrators who supply equipment to multiple regions with different supply standards.

The relay is designed with dual-channel monitoring using two inputs, ensuring redundancy and fault detection. This guarantees that faults such as cross-wiring, short circuits, or component failures are quickly identified and mitigated. By supervising devices such as emergency stop pushbuttons, guard doors, enabling switches, or light curtains, the relay ensures that dangerous machine movements are reliably brought to a safe state when triggered.

On the output side, the PNOZ X2.8P offers a robust contact configuration with 3 normally open (N/O) safety contacts and 1 normally closed (N/C) auxiliary contact. The N/O contacts are designed to disconnect power to actuators, drives, or motors, while the N/C auxiliary contact provides signalling for diagnostics or integration with higher-level control systems. This combination makes the relay both practical for safety control and efficient for system transparency.

The relay is tested in accordance with EN 60947-4-1 (AC/DC1 utilisation category), supporting reliable switching performance for both AC and DC loads. Rated for use with 240 V AC, it provides long service life even in high-demand environments where frequent switching is required. With a low power consumption of just 4.5 VA (AC) or 2 W (DC), it delivers energy-efficient performance that reduces operational costs and supports sustainable machine design.

Its compact and rugged construction makes installation straightforward and reliable, even in challenging industrial conditions. Clear terminal assignments simplify wiring and commissioning, while its durability ensures consistent performance over time with minimal maintenance requirements.

The PNOZ X2.8P is widely applied across industries including automotive, packaging, robotics, material handling, and process automation. It is particularly suited for small to medium-scale machinery that requires dependable safety monitoring with flexible supply voltage options.

In summary, the Pilz PNOZ X2.8P 24–240VAC/DC 3N/O 1N/C (777302) offers universal voltage compatibility, low energy consumption, dual-channel monitoring, and versatile contact outputs. It is a compact, efficient, and robust safety relay designed to provide high-level operator and machine protection while ensuring compliance with international safety standards.
