The Pilz P1HZ X1 24VDC 2N/O (part no. 774360) is a compact and efficient safety relay designed for monitoring two-hand control devices in compliance with international safety standards. Developed as part of Pilz’s long-standing portfolio of safety relays, it ensures that dangerous machine functions can only be activated when both operator hands are engaged, thereby reducing risks associated with accidental or unintended operation.

Operating at a 24 V DC supply voltage, the P1HZ X1 integrates seamlessly into modern industrial automation systems. Its low power consumption of just 2 W makes it highly efficient, supporting continuous use in energy-conscious production environments while keeping operating costs low.

This relay is equipped with two normally open (N/O) contacts, providing reliable and redundant safety outputs. These contacts ensure that safety-critical circuits are switched effectively, allowing hazardous movements to be enabled only under controlled and verified conditions. The redundancy built into the contact configuration is crucial for meeting high safety integrity levels, as it reduces the possibility of failure leading to unsafe operation.

The type IIIA two-hand control functionality is one of the defining features of the P1HZ X1. In this configuration, both hands of the operator must actuate controls within a defined time frame to initiate a machine function. This design prevents operators from accidentally starting machinery while one hand is in a danger zone, significantly enhancing safety during operations such as stamping, pressing, or other high-risk mechanical movements.

As with all Pilz safety relays, the P1HZ X1 is designed for robustness, reliability, and compliance. It is built to meet international standards for functional safety, supporting compliance with directives such as ISO 13849-1 and IEC 62061. By offering a simple yet highly reliable solution for two-hand monitoring, it reduces engineering complexity while ensuring maximum operator protection.

Applications for this safety relay include metalworking presses, cutting machines, stamping lines, assembly equipment, and automated machinery. In these scenarios, the P1HZ X1 plays a critical role in ensuring that operators remain at a safe distance from hazardous movements, while still allowing efficient workflow and machine performance.

Its compact construction also makes it suitable for control panels with limited space, supporting easy installation and integration. With straightforward wiring and clear functionality, the P1HZ X1 helps engineers implement reliable safety solutions without unnecessary complexity.

In summary, the Pilz P1HZ X1 24VDC 2N/O is a dependable safety relay that combines low power consumption, dual N/O outputs, and type IIIA two-hand control functionality into a compact and efficient design. By ensuring that machine activation requires deliberate two-hand operation, it delivers reliable protection for operators while supporting safe and productive machine use across industrial environments.
