The Pilz P2HZ X1 24VAC 3N/O 1N/C (part no. 774330) is a robust and dependable safety relay developed to ensure machine operators are fully protected during hazardous operations. Part of the well-established Pilz P2HZ series, this device provides reliable monitoring of safety functions and ensures machinery operates in compliance with international safety standards.

Operating at a 24 V AC supply voltage, the P2HZ X1 offers a low-voltage solution for modern automation systems, with a modest power consumption of 6 VA. This energy-efficient design supports long-term, continuous use while reducing operating costs and minimising heat generation within control cabinets.

The relay features a flexible contact arrangement, with 3 normally open (N/O) enabling contacts and 1 normally closed (N/C) monitoring contact. The enabling contacts allow machine functions to proceed safely only when all monitored safety conditions are met, while the monitoring contact provides feedback or fault detection for enhanced system transparency. This configuration ensures robust system performance and facilitates straightforward integration into diverse safety architectures.

One of the defining aspects of this model is its suitability for two-hand control applications, specifically type III C devices. In such applications, the relay ensures that both of an operator’s hands are required to initiate hazardous machine functions, reducing the risk of accidental activation and ensuring hands remain outside dangerous areas during operation. This makes it particularly suitable for machinery such as presses, stamping equipment, or other high-risk industrial systems.

The rugged design of the P2HZ X1 ensures long service life and consistent performance under demanding industrial conditions. Its durable construction withstands mechanical stress, frequent actuation cycles, and electrical noise, guaranteeing reliable performance over time. Clear terminal assignments and a straightforward wiring layout simplify commissioning and maintenance, supporting fast integration into new systems or retrofit applications.

As part of the Pilz safety relay family, the P2HZ X1 integrates seamlessly with other Pilz safety products, including emergency stop devices, guard door switches, and light curtains. This compatibility enables engineers to design modular, scalable safety systems that are compliant with standards such as ISO 13849-1 and IEC 62061, providing confidence in both operator protection and regulatory adherence.

In practical use, the P2HZ X1 24VAC is widely deployed in industries where operator safety is paramount, including automotive manufacturing, metalworking, packaging, and material handling. Its combination of reliable functionality, compatibility with two-hand controls, and energy efficiency makes it a trusted component for safeguarding both personnel and equipment.

In summary, the Pilz P2HZ X1 24VAC 3N/O 1N/C is a versatile and durable safety relay that delivers robust protection in industrial applications. With its 24 V AC supply, efficient 6 VA power usage, two-hand control compatibility, and flexible contact configuration, it provides engineers with a proven solution for building safe, standards-compliant automation systems.
