The Pilz P2HZ X4P 24VDC 3N/O 1N/C – 777355 is a safety relay designed specifically for two-hand control applications, providing maximum operator safety during hazardous machine operations. Built to comply with EN 574, Type III C requirements, this relay ensures that both operator hands must be engaged simultaneously to initiate a machine cycle, preventing unintended or accidental activation.

Operating on a 24 V DC supply, the P2HZ X4P integrates easily into existing safety and control systems. Its low power consumption of just 2.5 W makes it an energy-efficient solution, particularly beneficial in production environments where multiple relays and safety devices are deployed.

The relay features a contact configuration of 3 N/O (normally open) and 1 N/C (normally closed) contacts, offering flexibility for safety circuit design. The N/O contacts provide reliable enabling functions, while the N/C contact ensures secure feedback and monitoring of circuit integrity. This combination guarantees fail-safe operation and enhances diagnostic capability within the system.

A key functionality of the P2HZ X4P is its use in two-hand control circuits, essential in applications where operators must keep both hands clear of dangerous zones during machine actuation. Typical uses include presses, punching machines, stamping equipment, and other high-risk machinery where unintentional triggering could result in severe injury. The relay ensures that both hand-operated control devices are pressed within a defined time frame before the machine can start, eliminating unsafe shortcuts and enhancing compliance with safety regulations.

To protect the relay and connected systems, the device supports appropriate circuit breaker protection and conductor sizing, ensuring reliable operation in diverse industrial settings. Its robust design and durable construction guarantee long service life, even in demanding environments subject to vibration and frequent switching cycles.

The P2HZ series is well established as a reliable solution in Pilz’s extensive safety relay portfolio. Like other models in the range, the P2HZ X4P integrates seamlessly with Pilz’s safety controllers and relays, enabling scalable safety architectures tailored to the needs of modern automated systems.

In summary, the Pilz P2HZ X4P 24VDC 3N/O 1N/C – 777355 is a dedicated safety relay for two-hand control applications, providing energy-efficient operation, flexible contact configuration, and compliance with the highest safety standards. Compact, durable, and easy to integrate, it delivers dependable operator protection and ensures machinery operates within safe, regulated limits.
